摘要
针对当前水泥稳定碎石基层强度刚度较大带来的反射裂缝问题,提出了一种刚柔并济的新型基层材料:水泥乳化沥青复合胶浆稳定碎石,并在分析其微观结构及其性能特点的基础上,参照水泥稳定碎石路用性能指标进行了相应室内试验,通过对试验结果的分析,与同条件下水泥稳定碎石相比,水泥乳化沥青稳定碎石的刚性较低,抗干缩性能更好,能较好地延缓基层开裂。
The“reflect cracking ” problem is caused by the high strength and rigidity of cement Stabilized crushed stones base course, because of which this paper presents a new base course materials： cement-emulsified asphalt compound stabilized crushed stones. On the basis of analyzing the microstructure and performance specialty of it, this text make experiments referring to the pavement performance target of cement stabilized crushed stones. Analyzing the experiment result and comparing with cementstabilized crushed stones in the same standard, we find cement-emulsified asphalt stabilized crushed stones has lower rigidity and better dry-shrinking performance： it can delay base course cracking.
