摘要
研究制备了开级配沥青混合料试件,然后使用合理水灰比/灰砂比的水泥浆,浇注成半柔性路面试件。试件养生1 d和28 d后分别测定其力学性能和路用性能。结果表明,在油石比为4.5%的条件下,试件的抗压强度和间接拉伸强度最高。养生对半柔性路面材料性能的影响非常明显,经过28 d的养生,试件的抗压强度、间接拉伸强度、高温性能均有较大幅度的提高。
In this paper,the open graded asphalt mixture was prepared,and then using cement slurry with rational water-cement ratio/cement-sand ratio to cast semi-flexible pavement specimens.After curing for 1 day and 28 days,the mechanical properties and road performance of the specimens were determined.The results show that,when the asphalt aggregate ratio is 4.5%,the compressive strength and indirect tensile strength of the specimens are the highest.The curing has a significant impact on the properties of semi-flexible pavement materials,and after 28 days of the curing,the compressive strength,indirect tensile strength and high temperature stability of the specimens are greatly improved.
