Abstract
In November 2013, the Federal Aviation Administration (FAA) took delivery of Heavy Vehicle Simulator—Airfields (HVS-A Mark-VI). Full-scale accelerated pavement tests were performed using HVS-A to study the effect of high tire pressure effects on HMA airfield pavements. Two test pavements with 10-in. (250 mm) thick HMA surface and 12-in. (300 mm) thick aggregate base layer were trafficked bi-directionally with a radial aircraft tires (size 52 × 21.0R22) and 61,300 lbs (27.81 metric tons) wheel load. Tire pressure on one test pavement was 210-psi (1.45 MPa) and 254-psi (1.75 MPa) on the other test pavement. Embedded pavement sensors included asphalt strain gages (longitudinal and transverse) at the bottom of HMA layer, and pressure cells at the top of subgrade and aggregate base layer. Pavement performance during traffic tests was monitored by measuring surface profiles and straight-edge rut depth measurements at regular intervals. Laboratory characterization of HMA mix included dynamic modulus tests, and asphalt pavement analyzer (APA) tests. Full-scale accelerated pavement tests were completed. This paper presents the results from laboratory characterization of pavement materials, and the results of accelerated pavement tests on the effect of high aircraft tire pressures on HMA performance.
