Performance-Based Specifications for HMA Airfield Pavements Final Report AAPTP Project 06-03 MACTEC Reference 6420070021 September 10, 2009 x ABSTRACT The ultimate objective of this project is a framework for development and implementation of performance-based specifications for hot-mix asphalt (HMA) airfield pavements.

Guidelines for Use of Highway Specifications for HMA Airport Pavements. Airfield Asphalt Pavement Technology Program (AAPTP) Project 06-05 called for the development of guidelines to be used by practicing airport pavement design engineers on the utilization of state highway hot mix asphalt specifications for use in airport pavements. Quality Control – HMA and PCC • QC is the responsibility of the contractor. • AC 150/5370-10F General Provision Section 100 requires a Contractor Quality Control Program when P-401 or P-501 is in the project. • Specification items P -401 and P-501 contain minimum items to be included in the Contractor Quality Control Program.

HMA Control Chart Example The following is a simple example of a set of control charts that could be used for HMA in-place air voids. Actual paving data from the Washington State Department of Transportation (WSDOT) is used for all charts.

RCIP-VI test overlay consisted of two sections built with identical AC materials, the standard FAA P-401 HMA (PG 64-22), and equal thickness of 5 in. To evaluate the effect of extreme cooling cycle on the crack initiation and propagation, two distinct displacement rates were simulated by the TESS.

The last resurfacing job was in 2000 where the middle 32 ft of the taxiway were milled and replaced with a 2.5-in. Navy airfield mix (almost identical to a P-401 HMA surface course) containing 20% RAP. P-401 Specifications, Marshall and Gyratory Mixes; Bring your Laptop. FAARFIELD is the FAA’s pavement thickness design software. Participants are encouraged to bring laptop computers with FAARFIELD pre-installed to be able to perform hands-on classroom examples during the workshop.
