摘要
结合湖北省的气候条件和交通条件,指出该地区沥青路面所面临的主要病害危险在于高温稳定性和水稳定性.为减轻以上病害,借鉴Superpave胶结料PG分级成果提出适用的沥青等级;并结合路用性能试验,提出适用的面层各层次沥青混合料类型.
According to the climate and traffic in Hubei province, this paper analyses the main distress of asphalt pavement here is hot stability and water stability. In order to abate the distress, this paper raises the applicable grade of asphalt by means of Superpave PG of asphalt; through the test of the use performance, this paper raises the applicable gradation types of asphalt mixture at several levels of surface course.
