水泥乳化沥青稳定碎石劈裂强度试验研究

水泥乳化沥青稳定碎石混合料是以乳化沥青、水泥与水作为结合料,加入到符合规范要求的级配碎石中,在经过拌合、压实与养生,得到的符合抗压强度要求的混合料。作为一种新型的路面基层材料,对这种材料的劈裂抗拉强度性能在室内试验基础上作了系统的研究,结果表明：随着水泥剂量的增长,水泥乳化沥青稳定碎石混合料劈裂强度在增长;劈裂强度随着乳化沥青剂量的增加而减少;粗级配时混合料的劈裂强度较中值级配高;水泥乳化沥青混合料的劈裂强度随龄期的增长有一定增长,但不明显。

Research on the Test of Splitting Strength of Cement and Emulsified Asphalt Stabilized Stone Mixture

Adding cement and emulsified asphalt to grading stone,after mixing,compaction and health preserving,emulsified asphalt stabilized stone mixture was obtained.As a new type of road base material,the splitting strength of the material was tested systematically.Results show that splitting strength of cement and emulsified asphalt stabilized stone mixture increases with the increasing of cement content,but decreases with the increasing of emulsified asphalt content.Splitting strength of coarse grading mixture is...
