ACCELERATED PAVEMENT TESTING OF WARM MIX ASPHALT (WMA) FOR HEAVY TRAFFIC AIRFIELDS

摘要

This paper presents the results from accelerated pavement testing on warm-mix asphalt (WMA)mixtures designed for airfield pavements. Three WMA mixtures and one hot-mix asphalt (HMA)mixture produced in an asphalt plant were evaluated under simulated heavy aircraft traffic. Theevaluation was conducted at extreme traffic conditions including heavy aircraft loading, high tirepressure, and high pavement temperature. Pavement structural response and rutting wereevaluated to assess susceptibility to permanent deformation of WMA compared to that of HMAproduced using the same aggregate blend. Test results indicated that WMA is a viable productfor surface mixtures on airfield pavements.
