摘要
文章以广西某高速公里改建项目为依托,对水泥稳定再生集料半刚性基层的级配设计、强度特性和路用性能进行试验研究。结果表明再生集料半刚性基层的强度、模量指标能够满足行业标准对于高等级公路的半刚性基层路用性能要求,再生集料半刚性基层可应用于新建沥青路面基层。
Relying on the reconstruction project of a Guangxi expressway, this arti- cle con-ducted the experimental studies on the grading design,strength proper- ties and pavement performance of semi-rigid base from cement stabilized recy- cled aggregate.The results showed that the strength and modulus indicators of recycled aggregate semi-rigid base can meet the pavement performance re- quirements of industry standard for semi-rigid base of high-grade highways, and the recycled aggregate semi-rigid base can be applied to the base layer of new asphalt pavement.
