大粒径密级配沥青混凝土路用性能浅析

Analysis on Road Performance of Asphalt Concrete with Large Particle Size and Dense Grade

为提高基质沥青混凝土抗重载及抗车辙能力,对重载高速公路试验路段采用LSAM大粒径密级配沥青混凝土铺筑下面层,并进行了检测,结果证明大粒径沥青混合料具有良好的承载能力和路用性能,可被广泛推广使用。

For improving the heavy load resistance and anti-rutting performance, LSAM asphalt concrete with large particle size and dense grade was paved on the test section as bottom layer of heavy load expressway, and the performance was tested. The result shows that asphalt concrete with large particle size and dense grade has good heavy load resistance and road performance, which can be extended.
