## AAPTP UPDATE

- March 2007

**www.AAPTP.US**

**Notes:**
-Thanks for the opportunity to update you on the AAPTP Program.

- This will be a brief overview of the program (Click)
- The details of the program can be found on our web-site at www.aaptp.us

## AAPTP Background

- Program began 2004
- Cooperative Agreement
- Auburn University Contractor
- Projects are awarded as subcontract to Auburn University
- Organizational structure similar to NCHRP
- Funding obtained for FY-04 thru FY-06

**Notes:**
A quick overview of the program basics:
 - Authorized in the 2004 FAA Aviation bill that will expire at the end of 2007
 - Program is about 1 year behind.  Presently working on Projects funded with Fy-06 funds
 - Agreement provides $1.6 M/year for research on asphalt related pavement issues
    PCC pavement covered in a similar agreement with IPRF but they started a little earlier 2001

## AAPTP Status

- 12 Projects Awarded
- 1 Project in evaluation process
- Funding available for 7 new projects (FY-06)
- Approval and prioritization for 9 projects from FY-07 funds (not yet approved by Congress or FAA)

**Notes:**
 This a quick review of accomplishments:
  - 12 projects awarded, 1 in evaluation process and 1 we will received proposal shortly
     In the 13 projects receiving proposal – we have received 60 proposal from 34 organizations
  -  After the beginning of the year I will be issuing RFP’s for the 7 projects that were approved for FY-06 funds
       If there is anyone that has an interest in serving on one the technical panel for these project – please let me know
  - The Program Coordination Group met in Oct and approved and prioritized project for FY-07 funding
     This funding has not been appropriated by congress and initial drafts of the bill cuts the funding for this and the IPRF program significantly but we are hopeful that full funding will be restore in the committee compromise legislation. 

## Project Status Update

- FY-04 Projects Include:
-    Rubblization, PG Binder, Superpave, SMA Longitudinal Joints, & Porous Friction Course
- Project to be complete in 2007:
-    Rubblization, PG Binder, Longitudinal Joints and Porous Friction Course

- 06-02  RFP March 2007 (Funds $150K)
- 06-03  RFP March 2007 (Funds $190K)
- 06-04  RFP April 2007 (Funds $190K)
- 06-05  RFP May 2007 (Funds $190K)
- 06-06  RFP June 2007 (Funds $100K)
- 06-07  RFP August 2007 (Funds $195K)

**Notes:**
FY-06 Projects are Identified as “Future Projects” but funding has been received and technical panels are being formed.  Here are the anticipated dates for the RFP and corrected to the initial project funding amount
  -  If anyone has a desired to learn more about the process and experience/knowledge in one of these area you are encourage to volunteer 
  -  Here are the estimated dates when the request for proposals will be issued for each project

## Proposed Project for FY-07

- 07-01 Improved Shear Strength to Accommodate Higher Tire Pressures
- 07-02 Improved Mix Design Construction and Maintenance of Grooved HMA Airfield Pavements
- 07-03 Guidelines for Design and Application of Tack and Prime Coat for Airport HMA Pavements
- 07-04 Evaluation of Failure Mechanisms for HMA Airfield Pavements
- 07-05  Mechanistic Properties of FAA HMA Standard Specification Materials

**Notes:**
In Oct the PCG meeting and developed a list of projects for funding with FY-07 funds.  Here is a brief summary of projects:

07-01 – The new generation of airbus and Boeing will have tire pressure that are on the upper edge and maybe a little beyond currently accept practice for commercial aircraft.  These tire pressures will be in the 220-230 range and the performance of HMA may be severely test on sharp turns.  This project will access the failure mechanism and address issues that will improve the shear resistance of HMA
07-02 – Closing of the grooves on HMA pavement is a issue that needs addressing.  This project will look at the mix properties and  and maintenance practices along with alternative to grooving
07-03 – Most tack and prime cost standards and needs were developed from highway usage.  Airport situation and needs are not the same and this project will look at the prime and tack cost issues from a airport perspective and develop guidelines tailor to airport use.
07-04 – This project will look at the test data and results from previous full scale experiments at the FAA test facility in Atlantic City and evaluate the present HMA failure criteria.
07-05 – This project will provide test data and mechanistic properties of Standard FAA materials for use in the new mechanistic based design procedures

## FY-07 Projects (cont.)

- 07-06 Use of Accelerated Laboratory Tests to Develop Improved Rutting Predictions Models for Airfield Pavement
- 07-07 Model Data Base Collection of HMA Airfield Construction Data
- 07-08  Development a Web Based Information System for Airfield HMA Best Construction Practices Manual
- 07-09 Investigate Severity, Extent and Corrective Measures for Segregation on HMA Airfield Pavements

**Notes:**
07-06 – This project will look at existing rutting laboratory testing equipment and determine I ,modification or new equipment to provide and good prediction of rutting of airfield pavements from laboratory tests
07-07 – This project will develop a standard method for collecting construction data on HMA airport pavements into a data base
07-08 – This project will provide a web based product to distribute the result of project 05-01 “Best Practice HMA Airport Pavement Construction Manual – fully documented with hyper links and fully accessible
07-09 – This project will look at the segregation issues and provide some guidelines on the corrective measures and potential for future damage to accelerate.
