4 Pavement Evaluation Report District 7 June 2012 EXECUTIVE SUMMARY Airfield pavement facilities represent a large capital investment in the Florida Airport System. Timely airport maintenance and strategic rehabilitation are essential as repair costs increase significantly in proportion to deterioration. Airport distresses can also contribute to the development of loose debris and decreased rideability quality, which can be a significant safety concern for aircraft. In 2010, the FDOT Aviation Office selected a Consultant team consisting of Kimley-Horn and Associates, Inc. and their Subconsultants, AMEC, Penuel Consulting, LLC and All About Pavements, Inc., to provide services in support of FDOT in the continuing evaluation and updating of the existing SAPMP to be completed over fiscal years 2011 and Pavement condition surveys were performed for airside pavements for the following airports located in District 7: BKV Hernando County Airport CGC Crystal River Airport CLW Clearwater Airpark PCM Plant City Airport PIE St. Petersburg-Clearwater International Airport SPG Albert Whitted Airport TPF Peter O Knight Airport VDF Tampa Executive Airport X40 Inverness Airport ZPH Zephyrhills Municipal Airport Tampa International Airport, which is managed by the Hillsborough County Aviation Authority, declined to participate in the FDOT SAPMP and therefore was not inspected as part of this update. District 7 s overall is at a 73, which corresponds to a Satisfactory condition. Table I: Condition Summary by Airport below represents the results of the inspection at each airport within the District. Average values for the airports in District 7 ranged from 61 (Fair) to 96 (Good). Specific individual airport results are identified in individual airport reports provided to the airports. Table II: Runway Condition Summary by Airport indicates the values for every runway within the District, grouped by airport. Figure I-A: Runway Condition graphically depicts the percentage of the District s runways below the FDOT Minimum, and Figure I-B: Runway Pavement Condition Comparison to FDOT Minimum shows the s of the District s runways in comparison to the FDOT Minimum. iii

14 Pavement Evaluation Report District 7 June INTRODUCTION 1.1 Project Background The State of Florida has more than 100 public airports that are vital to the Florida economy as well as the economy of the United States. There are millions of square yards of pavement for the runways, taxiways, aprons and other areas of these airports that support aircraft operations. The timely and proper maintenance and rehabilitation of these pavements allows the airports to operate efficiently, economically and without excessive down time. In order to support the planning, scheduling, and design of the M&R activities based on pavement evaluation and pavement management performance trends, the Florida Department of Transportation (FDOT) Aviation Office implemented the Statewide Airfield Pavement Management Program (SAPMP) in In 2010, the FDOT Aviation Office selected a Consultant team consisting of Kimley-Horn and Associates, Inc. and their Subconsultants, AMEC, Penuel Consulting, LLC and All About Pavements, Inc., to provide services in support of FDOT in the continuing evaluation and updating of the existing SAPMP to be completed over fiscal years 2011 and Pavement condition surveys were performed for airside pavements for the following airports located in District 7: BKV Hernando County Airport CGC Crystal River Airport CLW Clearwater Airpark PCM Plant City Airport PIE St. Petersburg-Clearwater International Airport SPG Albert Whitted Airport TPF Peter O Knight Airport VDF Tampa Executive Airport X40 Inverness Airport ZPH Zephyrhills Municipal Airport Tampa International Airport, which is managed by the Hillsborough County Aviation Authority, declined to participate in the FDOT SAPMP and therefore was not inspected as part of this update. 1.2 Purpose The primary goal of the SAPMP update is to provide individual airports with pavement condition ratings as well as recommendations for immediate and long-term major rehabilitation on the basis of pavement condition. This approach is intended to focus pavement M&R in areas where the most urgent need is with the overall goal of minimizing costs by improving pavements before they deteriorate to a point where the cost to rehabilitate is increasing at a higher rate than would have been experienced if repaired earlier. 1

15 Pavement Evaluation Report District 7 June 2012 Figure 1-1: Pavement Life Cycle below, taken from FAA/AC A Airport Pavement Management Program, illustrates how a pavement generally deteriorates and the relative cost of rehabilitation at various times throughout its life. Note that during the first portion of a pavement s life, it performs relatively well. After that, however, it begins to deteriorate rapidly. The number of years a pavement stays in good condition depends on how well it is maintained. As the illustration demonstrates, the cost of maintaining the pavement above a critical condition before rapid deterioration occurs is much less compared to maintaining pavements after substantial deterioration has occurred. Figure 1-1: Pavement Life Cycle Source: FAA/AC 150/5380-7A Airport Pavement Management Program *Modified to reflect current construction costs. The inspections and analysis that were done were performed in accordance with the methods identified in ASTM D and in the FAA Advisory Circular 150/5380-6B to comply with the FAA Airport Improvement Program (AIP) requirements. The tasks required to achieve this objectives at each airport include: Obtain recent construction history from the Airport to update the Pavement Inventory CADD drawings and database from the previous SAPMP update; Perform a visual Pavement Condition Index () survey of the airfield pavements at the Airport; Update the MicroPAVER database to analyze the field data and determine the current condition of the airfield pavements; Predict the future deterioration of the pavements using performance models based on condition data collected from current and previous inspections; 2

16 Pavement Evaluation Report District 7 June 2012 Develop a 10-year M&R plan to address the pavement maintenance/rehabilitation needs; Estimate the anticipated costs associated with the suggested immediate and future M&R activities based on statewide average construction costs. This document is intended to serve as a district summary of airport facility pavement condition and both immediate and long-term major rehabilitation based on needs for each airport. Furthermore, this document is intended to: Describe, briefly, the Florida Department of Transportation Aviation Office Statewide Airfield Pavement Management Program and the roles and responsibilities of the program s participants; Provide information on the pavement management principles, objectives, and methods used to update the existing program; Provide average results of the survey at each airport based on pavement facility use, ranking, and type (i.e. Runway, Taxiway, Apron, Primary, Secondary, Tertiary, AC, AAC, APC, PCC, etc.); Provide the results of the M&R Analysis that identified both the immediate and 10-Year major rehabilitation project needs on an airport and district wide basis. 3

17 Pavement Evaluation Report District 7 June SYSTEM INVENTORY AND AIRPORT NETWORK DEFINITION DEVELOPMENT 2.1 System Inventory Update A significant element to the development and update of the SAPMP has been to identify recent and anticipated construction activity that affects the pavement composition and performance. With cooperation from the airport facility personnel, the project team was able to gather airport specific information that included changes in pavement geometry, new or reconstructed pavements since the last inspection and anticipated pavement rehabilitation that would negate the findings of a visual inspection done in the short term. At the beginning of each phase for this update, FDOT SAPMP participants responded to the Aviation Office with project specific information on the recent and anticipated work. In addition to the construction activity, updates to pavement facility designators (i.e. re-designation, magnetic declination, and/or decommissioning) were reported. This information was considered during the updating of pavement section areas on the individual airport Network Definition Map. The construction activity information provided by the airport is depicted on the System Inventory Update Map for each facility. This information was also included in the updates to the SAPMP specific MicroPAVER software database. 2.2 Network Definition Update Based on the information identified in the System Inventory Map, the geometry of the Network Definition specific to the pavement area sections has been updated to reflect the changes. The purpose of developing pavement area sections is to track future pavement performance as well as to plan for future projects. The Network Definition Map categorically identifies pavement geometry, pavement composition, and sample identification. The updated areas by use for each airport are summarized in Table 2-1: Summary of Area by Use by Airport. Figure 2-1: District Pavement Area by Use below depicts the district pavement area by use, and Figure 2-2: Pavement Area by Use by Airport provides a breakdown of pavement area by usage at each airport. 4

20 Pavement Evaluation Report District 7 June PAVEMENT EVALUATION 3.1 Pavement Condition Survey The pavement condition survey was performed using the methods described in ASTM D and FAA Advisory Circular 150/5380-6B. These inspections were performed by a minimum of two inspection personnel that have undergone appropriate FDOT training, demonstrated adequate experience, and have been approved by AO-PM. The visual surveys were performed with significant coordination with airport personnel to ensure minimal impacts on airport operations while maintaining safety. When appropriate, pavement inspectors were escorted by authorized airport personnel. The inspection of pavement facilities is limited to the identified sample units. The number of sample units inspected in each pavement section was determined to achieve a confidence level of representative distresses throughout the facility. The sampling rate used for the FDOT SAPMP is identified in Table 3-1: Sampling Rate for FDOT Condition Surveys. Table 3-1: Sampling Rate for FDOT Condition Surveys AC Pavements PCC Pavements N n n N Runway Others Runway Others >51 Where % but < % but < >51 N = total number of sample units in Section n = number of sample units to inspect % but < % but < Pavement Condition Summary The pavement condition results from each airport have been developed by analyzing the specific pavement distresses using U.S. Army Corp of Engineers CERL MicroPAVER software. In adherence to the ASTM D , the pavement condition index ranges from 100 to 0 with corresponding condition ratings of Good to Failed, respectively. Figure 3-1: Rating Scale depicts the standard index with the corresponding condition ratings and color identification used for this program update. 7

The pavement facility ranking was established during the 1998/1999 survey and has been updated based on airport feedback. Primary pavements are considered to be of highest importance, examples include a primary runway and its parallel taxiway. Secondary pavements examples include a secondary crosswind runway and its parallel taxiway. Tertiary pavements examples can be active aprons such as a maintenance area or a non-active aircraft equipment storage apron. 10

25 Pavement Evaluation Report District 7 June MICROPAVER ANALYSIS 4.1 Performance Modeling A significant benefit of consolidating Florida s Airport System s pavement infrastructure within the FDOT SAPMP is the large amount of pavement condition data recorded using consistent methods of measurement. The historic pavement condition, or performance trend, has been compiled throughout the entire State system since the inception of the SAPMP and is used in the development of Performance Models. These models have been categorically arranged and developed to predict the future conditions of pavements based on Florida s specific characteristics of climate, construction materials, and operations. Each model has been developed based on the following criteria: AIRPORT TYPE (Primary, Regional Reliever, or General Aviation) > FACILITY USE (Runway, Taxiway, or Apron) >>FACILITY SURFACE TYPE (AC, AAC, APC, or PCC) The following figure, Figure 4-1: Example Performance Model, represents the condition data collected for all participating General Aviation airport runways constructed of AC pavement. The approximate deterioration observed for these pavement types, excluding outliers, is about 1.5 points per year. Appropriate curves have been developed for the identified airport types, facility use, and pavement material. Figure 4-1: Example Performance Model: FDOT-GA-RW-AC Pavement Condition Index Expected to deteriorate to FDOT Minimum of 75 FDOT-GA-RW-AC Age (Years) Predicted Model FDOT Minimum 75 12

26 Pavement Evaluation Report District 7 June 2012 The historic trends of pavement performance at Florida airport facilities for all performance models are consolidated within the program database. This information is utilized in the prediction of pavement performance based on the current determined from the inspections that took place between 2011 and Major rehabilitation is planned based on the predicted. The intent of this for both the individual airport and the District to be aware of anticipated rehabilitation work based on condition. 4.2 Maintenance Policies FDOT utilizes the distress data collected to estimate maintenance work efforts for pavement area sections that would benefit from this work, specifically sections with a ranging from 65 to 100. Examples of maintenance work include crack sealing, area patching, seal coat applications, and other routine maintenance efforts that typically can be performed in a short time frame by airport maintenance personnel. This maintenance, or repair-type activity, is intended to preserve and extend pavement condition above the critical condition. Table 4-1: Routine Maintenance Activities for Airfields provides the list of the maintenance activities used in MicroPAVER to treat specific distress types based on the FDOT Distress Repair and Maintenance Manual. MicroPAVER applies repairs to these distresses and adjusts the based on specific rules. These repairs are used only in the first year of an analysis. 13

This critical point is called Critical. The critical levels for different pavement and branch types established in the previous SAPMP update were used in this update for the development of the Major M&R plan for the airports. Sections 14

28 Pavement Evaluation Report District 7 June 2012 above critical levels receive routine maintenances while pavements predicted to deteriorate below their respective critical level during the analysis period will be identified for Major M&R. Appendix B identifies the Cost by Condition and Critical used in the development of major rehabilitation. Table 4-2: M&R Activities by Condition summarizes the M&R activities based on values, as established by the FDOT. Table 4-2: M&R Activities by Condition Maintenance Rehabilitation Activity Crack Sealing and Full-Depth Patching Mill and Overlay (AC) or Concrete Pavement Restoration (PCC) Reconstruction Trigger Special consideration is given to pavements that exhibit a significant amount of structural distresses while maintaining a above the critical condition. The presence of structural distresses may be attributed to the greater fatigue load being applied to the pavement than the original design capacity. Therefore in certain situations, pavement sections may be triggered for work due to structural distresses found rather than solely based on values determined. 4.4 Budget Analysis Approach The scope of this update was to identify the overall work required for major rehabilitation using comparative costs based on the condition survey and predicted pavement performance. As mentioned previously, the criteria for major rehabilitation is based on the MicroPAVER set critical of 65. From the previous SAPMP updates, FDOT has developed desired minimum values based on the airport type and facility use, which are shown in Table 4-3: FDOT Minimum Service Levels. The rehabilitation activity identified is based on the critical of 65. Table 4-3: FDOT Minimum Service Levels Use FDOT Minimum GA RL PR Runway Taxiway Apron

29 Pavement Evaluation Report District 7 June 2012 The development of major rehabilitation work expressed in the individual airport reports was based on an unlimited budget or unconstrained budget scenario. This scenario was selected in particular as a means to identify project activity based on the condition need. This information is intended to be used as a planning tool to determine project selection based on airport priority, facility use, and traffic demand, among other factors. The major rehabilitation costs of the projects identified are determined using a cost scale range based on the of the pavement area sections. The cost study performed for pavement work such as mill and overlay and reconstruction identified varying costs based on airport type. The schedule of costs used for the major rehabilitation is referenced in Appendix B. 4.5 Immediate Major Rehabilitation Need Based on the condition surveys performed in 2011 and 2012, major rehabilitation has been identified for pavement area sections that resulted in a current condition below 65. The following table, Table 4-4: Summary of Immediate Major Rehabilitation Needs, identifies the immediate major rehabilitation need for each airport under the unlimited funding scenario. The breakdown of these costs on an individual airport basis can be found in Appendix C.

34 Pavement Evaluation Report District 7 June CONCLUSION The FDOT Aviation Office has updated the through the pavement condition surveys performed at each participating airport and preparation of M&R planning information in compliance with the FAA Advisory Circular 150/5380-6B. MicroPAVER software was utilized to determine pavement conditions in accordance with ASTM D and develop maintenance and rehabilitation policies consistent with the FDOT Aviation Office policies. These policies were used to identify pavement rehabilitation projects based on the condition of the pavement over a 10-year period that are detailed in the individual airport reports and in Appendix C. This study was focused on identifying current pavement condition and using a condition based tool to assist in the evaluation of pavement performance and identify and prioritize maintenance and rehabilitation needs and costs to maximize useful pavement life. The methods used to determine pavement condition for this program update, as with previous updates, have been performed in accordance with ASTM D The process is intended to provide airport sponsors with guidance in planning pavement maintenance and rehabilitation projects and funding agencies with planning tools for allocation of funds. A detailed breakdown of pavement condition for each airport is included in Appendix C. As can be seen in this report and by comparing pavement conditions on an airport by airport basis, there is a wide variation in pavement conditions between airports. Recommended major rehabilitation recommendations for each airport are also included in Appendix C. High priority runway projects, based on pavement conditions below the FDOT recommended minimum service level of 75, which the District should consider as immediate needs are listed below. These are not all the needs at each airport in the District and may not be the individual airport s priority, but should be considered in development of funding programs.

36 APPENDIX A GLOSSARY OF TERMS

37 District Pavement Evaluation Report Glossary Aviation Office - The Aviation Office is charged with responsibility for promoting the safe development of aviation to serve the people of the State of Florida. The Aviation Office Program Manager (AO-PM) has review and approval authority for each program task of the SAPMP. Branch - A Branch designates pavements that have common usage and functionality, such as an entire runway, taxiway, or apron. Category - The Category classifies the airport according to the type and volume of aircraft traffic, as follows: GA for general aviation or community airports; RL for regional relievers or small hubs; PR for primary (certified under Part 139 requirements). Critical - The value considered to be the threshold for M&R decisions. above the Critical generate economical activities expected to preserve and prolong acceptable condition. M&R for values less than Critical make sense only for reasons of safety or to maintain a pavement in operable condition. A pavement section is expected to deteriorate very quickly once it reaches the Critical and the unit cost of repair increases significantly. Distress Type - A distress type is a defined visible defect in pavement evidenced by cracking, vertical displacement or deterioration of material. In technology, 16 distinct distress types for asphalt surfaced and 15 for Portland Cement Concrete surfaced pavements have been described and rated according to the impact their presence has on pavement condition. Florida DOT (FDOT) - Florida Department of Transportation was represented in this project by the Office of Aviation. Localized M&R (Maintenance and Repair) - Localized M&R is a temporizing activity performed on existing pavement to extend its serviceability and/or to improve rideability. Localized M&R can be applied either as a safety (stop-gap) measure or preventive measure. Common localized maintenance methods include crack sealing, joint sealing, and patching. Major M&R (e.g. Rehabilitation) - Activities performed over the entire area of a pavement Section that are intended to restore and/or maintain serviceability. This includes asphalt overlays, milling and replacing asphalt pavement, reconstruction with asphalt, reconstruction with Portland Cement Concrete (PCC) pavements, and PCC overlays. MicroPAVER - A commercially available software subsidized by FAA and agencies in the US Department of Defense developed to support engineered management of pavement assets using a condition based approach. This software has the functionality such that, if properly implemented, maintained, and operated, it meets the pavement management program requirements described by the FAA in Advisory Circular 150/5380-7A. Minimum Condition Level - A threshold value established by FDOT to represent the targeted minimum pavement condition that is desirable in the Florida Airport System. These values were established with consideration of pavement function and airport type. For instance, runways have higher minimum condition levels than aprons, and Primary airports have higher minimum condition levels than General Aviation airports. A-1

38 District Pavement Evaluation Report Glossary (Continued) Network Definition - A Network Definition is a Computer-Aided Drafting & Design (CADD) drawing which shows the airport pavement outline with Branch and Section boundaries. This drawing also includes the sample units and is used to identify those sample units to be surveyed, i.e. the sampling plan. The Network Definition for the airport is in Appendix A along with a table of inventory data. Pavement Condition Index () - The Pavement Condition Index is a number which represents the condition of a pavement segment at a specific point in time. It is based on visual identification and measurement of specific distress types commonly found in pavement which has been in service for a period of time. The definitions and procedures for determining the are found in ASTM D 5340, published by ASTM International. Pavement Evaluation - A systematic approach undertaken by trained and experienced personnel intended for determination of the condition, serviceability, and best corrective action for pavement. Techniques to standardize pavement evaluation include the Pavement Condition Index procedures. Pavement Management System (PMS) - A Pavement Management System is a broad function that uses pavement evaluation and pavement performance trends as a basis for planning, programming, financing, and maintaining a pavement system. Pavement Surface Type - The surface of pavement is identified as one of four types: AC for asphalt surface pavements; PCC for Portland Cement Concrete pavements; AAC for asphalt surface pavements that have had an asphalt overlay at some point in their construction history; APC for composite pavements, which consist of asphalt over Portland Cement Concrete pavement. PAC for composite pavements, which consist of Portland Cement Concrete over asphalt pavement. Rank - Pavement rank in MicroPAVER determines the priority to be assigned to a pavement Section when developing an M&R plan. Pavement Sections are ranked as follows according to their use: P for Primary pavements, such as primary runways, primary taxiways, and primary aprons; S or Secondary pavements, such as secondary runways, secondary taxiways, and secondary aprons; T for Tertiary pavements such as T hangars and slightly used aprons. Reconstruction - Reconstruction includes removal of existing pavement, preparation of subgrade, and construction of new pavement with new or recycled materials. Reconstruction is indicated when distress types evident at the surface indicate failure in the pavement structure or subgrade of a type, and to an extent, not correctable by less extensive construction. A-2

39 District Pavement Evaluation Report Glossary (Continued) Rehabilitation - Rehabilitation represents construction using existing pavement for a foundation. Rehabilitation most commonly consists of an overlay of existing pavement with a new asphalt or concrete surface. Recently, technology has expanded the options to include recycling of existing pavement and incorporating engineering fabrics or thin layers of elasticized materials to retard reflection of distress types through the new surface. Sample Unit - Uniformly sized portions of a Section as defined in ASTM D Sample units are a means to reduce the total amount of pavement actually surveyed using statistics to select and survey enough area to provide a representative measure of Section. Sample Unit sizes are 5,000 ± 2,000 square feet for AC-surfaced pavements and 20 ± 8 slabs for PCC-surfaced pavements. Section - Sections subdivide Branches into portions of similar pavement. Sections are prescribed by pavement structure, age, condition, and use. Sections are identified on the airport Network Definition. They are the smallest unit used for determining M&R requirements based on condition. (SAPMP) The Statewide Airfield Pavement Management Program is a program implemented in 1992 by the Florida Department of Transportation to plan, schedule, and design the maintenance and rehabilitation activities necessary for the airfield pavement on Florida s public airports to allow the airports to operate efficiently, economically, and without excessive down time. System Inventory - A System Inventory is a Computer-Aided Drafting & Design (CADD) drawing which shows the airport pavement outline and identifies airfield construction activities since the last inspection. The System Inventory for the airport is included in Appendix A. Use - In MicroPAVER, Use is the term for the function of the pavement area. This is either Runway, Taxiway, or Apron for purposes of the FDOT Statewide Aviation Pavement Management System. A-3
