ABSTRACT
Two outdoor flexible pavement test lanes and one indoor test lane were constructed at the Federal Aviation Administration’s (FAA) National Airport Pavement and Materials Research Center (NAPMRC) to study the effect of high tire pressure on the performance of Warm Mix Asphalt (WMA) surface layer. The Airport Pavement Test Vehicle (Heavy Vehicle Simulator—Mark VI Airport) was used to perform the full-scale tests. The objectives of Test Cycle 1 (TC1) included tire pressure effects on Warm Mix Asphalt (WMA), effect of binder grade on WMA performance, and comparison of WMA performance under aircraft wheel loads, and different pavement temperatures. This paper summarizes results from traffic tests performed on Test Cycle-1 (TC-1) WMA test sections.
