Testing and Evaluating the High-Temperature Rutting Development of Steel Deck Asphalt Pavement Using Full-Scale Accelerated Pavement Testing

CODEN: JTEVAB

Abstract

Steel deck asphalt pavement (SDAP) significantly differs from traditional pavement in terms of substructure and service environment, so its rutting development is unique. Indoor tests and the finite element method cannot competently simulate service environment and accurately show the rutting development of SDAP. In this study, the rutting development of SDAP was evaluated using full-scale accelerated pavement testing (APT). First, a steel bridge with two different pavement structures was constructed and a heating system was installed to keep the high temperature. Second, three indoor tests—dynamic stability (DS), hardness number (HN), and indentation—were conducted to quantify the rutting resistance of pavement materials, and the Mobile Load Simulator 66 executed the APT. The indoor results showed that DS and HN correlated well with the APT rut depth. With the increase of APT loading cycles, the rutting depth, the ratio of sag area to uplift area, and the ratio of sag area to full areas were increased. Meanwhile, the rutting depth changing speed and the ratio of uplift area to full areas declined with the loading. A rutting depth prediction model (RPM) was proposed based on the number of loading cycles and the initial rutting depth at 5,000 loading cycles. The RPM applied well to the previous study’s test data, indicating that rut development can be evaluated by its early status.
