【Abstract】 Building materials, which are wear-resisting and skid-resisting, are needed in paving asphalt surface course of the high-type highway. The basic igneous rock distributes widely in north China. The early study of basic igneous rock is mainly centered on lithology and content of metal ore bearing, but its physical characteristics are ignored. This paper explains the significance on the application of gabbro-diabase through aptitude test and experiment of gabbro-diabase in asphalt surface course of the high-type highway.更多还原
