Combining with the actual situation of Guangxi Baise to Jingxi highway,this paper made contrast test to the chemical composition of di-abase and basalt,basic performance,asphalt basic properties,mix ratio design and asphalt concrete AC-13C road performance,the results showed that:in Guangxi such a serious lack of basalt aggregate area,used the locally produced diabase as asphalt concrete coarse aggregate would greatly reduce the engineering cost,shorten the construction period,brought higher economic benefits to the local area.%结合广西百色至靖西高速公路的实际情况，对辉绿岩和玄武岩的化学组成、基本性能，沥青基本性能，配合比设计和沥青混凝土AC-13C路用性能进行了对比试验，结果说明：在广西这样严重缺乏玄武岩集料的地区，用当地产的辉绿岩作为沥青混凝土的粗集料会大大降低工程造价，缩短施工工期，给当地带来较高的经济效益。
