摘　　要：利用MLS66型加速加载试验设备进行大粒径沥青碎石结构路面和常规结构路面的对比加速加载试验,通过对相同试验条件下的车辙数据和弯沉数据的分析,结果表明:高温条件下,常规结构路面和大粒径结构路面抗车辙能力基本相同;相同试验条件下,两种路面结构强度随加载次数的增加而减小,大粒径结构强度衰减的速率更大。Comparative acceleration loading tests for large grain size asphalt macadam structure pavement and conventional structure pavement are performed by utilizing MLS66 acceleration loading test equipment and the analysis on rutting data and deflection data under the same test condition is made. The results show that： the anti -rutting capacity of conventional structure pavement and large grain size structure pavement is basically same under high temperature condition; the structural strength of two kinds of pavements will decrease with the increase of number of times of loading, and degenerative rate of large grain size structural strength is larger.
