摘要
肃航项目周边地区集料资源匮乏,项目充分利用当地资源,将破碎砾石作为集料应用于沥青下面层,保证公路质量的同时,极大地降低了公路建设成本。本文充分依托肃航公路,对破碎砾石类沥青混合料进行了配合比设计,并对混合料的各项性能进行了研究。研究表明,破碎砾石沥青混合料的各项性能均能满足要求。
Su Hang road is located in the remote area of GanSu Province, where is short of the aggregate for road construction. In this condition, The project makes full use of local resources——broken gravel as aggregate used in the following layer. The quality is guaranteed, meanwhile, the cost will be reduced sharply in this way. Relying on SuHang Road, mix has been designed and qualities have been investigated in this paper. The results show that mixture made with broken gravel has great water and temperature stability.
