Abstract
A large-scale accelerated pavement testing (APT) with mobile load simulator 66 (MLS66) was carried out in an indoor structure groove, in order to investigate the performance development of asphalt pavement with semi-rigid base and fine-sand subgrade. The test was conducted with 20% overload and external heating system. Rutting deformation, seismic modulus (measured by portable seismic pavement analyzer), damage mode of asphalt layers and volume parameters were measured. In addition, stress and deformation of fine-sand subgrade were also analyzed. Results indicate that shear flow deformation occurred, and no cracking was observed during diagnostic excavation. Relationship between rutting depth and loading applications was piecewise linear. The average seismic modulus decreased by a quarter after loading compaction. Compaction of upper and middle asphalt layers could be also one of critical factors for the resistance of shear flow deformation of asphalt mixture at high average temperature. Moreover, phase rate of rutting deformation and lateral upheaval coefficient (proportion of the maximum height of lateral upheaval to the maximum rutting depth) were appropriate to be evaluation indicators.
