水泥-乳化沥青稳定碎石基层路用性能研究

Experimental study on road performance of cement-emulsified asphalt stabilized macadam

从无侧限抗压强度、高温稳定性、低温抗裂性、水稳定性及收缩性几个方面对水泥-乳化沥青稳定碎石混合料应用于道路基层的路用性能进行了试验研究.试验结果表明:水泥-乳化沥青稳定碎石混合料具有优异的高温性能和良好的抗压、低温抗裂、水稳定和收缩性能,可应用于修筑各等级公路的基层.

Road performance of base course which cement emulsified asphalt stabilized macadam is applied to, was researched in several aspects,including un-confined compressive strength, high- temperature stability, low-temperature crack resistant, water stability and shrinkage property. The results show that cement - emulsified asphalt stabilized macadam has excellent high-tempera- ture stability, good compressive strength, good low-temperature crack resistant, good water stability and shrinkage property, which can be applied to construct undersurface course or base course of generic road, and base course of highway.
