摘要
介绍了半柔性路面基层及混合料的特性,采用扫描电镜观测水泥乳化沥青碎石混合料的微观结构特征,结果表明:水泥乳化沥青碎石混合料由沥青包裹的碎石粉、未水化水泥组成的粒状颗粒和纤维状水泥水化产物等构成,其路面基层混合料的力学性能满足规范要求。
The characteristics of semi-flexible base and mixture are introduced. The features of microstructure of cement emulsified asphalt mixture are observed through scanning electron microscope. The results indicate that cement emulsified asphalt mixture consists of gravels wrapped by asphalt, cement grains and thready hydrated production of cement; the mechanical properties of mixture can satisfy the requirements of specification.
