Warm-Mix Asphalt for Airfield Pavements

This paper describes an evaluation program conducted by the U.S. Army Engineer Research and Development Center to determine the suitability of using warm-mix asphalt (WMA) technologies for airfield pavements. The work consisted of two main phases. Phase I consisted of laboratory evaluations of the performance of different WMA technologies and included tests for rutting, durability, low-temperature cracking, moisture damage, binder properties, and workability. Phase II consisted of evaluating production and placement procedures and conducting accelerated pavement testing on full-scale test sections under simulated full-scale military aircraft traffic to evaluate rutting performance. In both phases the performance of mixtures produced using different WMA technologies was compared to that of the same mixtures produced at hot-mix asphalt (HMA) temperatures. WMA was recommended as a viable alternative to HMA for use on heavily trafficked airfield pavements. The Unified Facilities Guide Specification (UFGS) 32 12 15.16 was developed along with two Engineer Technical Letters (ETL) to provide guidance for using WMA on airfield pavements.
