Full-Scale Accelerated Pavement Testing of Warm-Mix Asphalt (WMA) for Airfield Pavements
Abstract
This report presents results from full-scale accelerated pavement testing of warm-mix asphalt (WMA) mixtures designed for airfield pavements. Three WMA mixtures were evaluated and compared to a control hot-mix asphalt (HMA) mixture. Data are presented from instrumented pavement test sections of WMA and HMA trafficked using a heavy-vehicle simulator (HVS-A) configured with an F-15E military jet aircraft wheel with a high load, high tire pressure and at high pavement temperatures. Surface permanent deformation is presented as a function of number of traffic cycles for the different pavement sections. Pavement instrumentation data are presented to show that rutting performance was not influenced by any differences in the structural capacity of the supporting layers. Additional testing was conducted on areas of the test sections not trafficked by the HVS-A to assess any potential problems associated with grooving the surface of WMA airfield pavements and to compare the performance of grooved WMA to that of grooved HMA. The results from this research demonstrated that WMA is a viable alternative to HMA for use on heavily trafficked airfield pavements.
