沥青混合料基灌注式半刚性路面是由基体沥青混合料和灌注复合水泥胶浆两部分组成,基体沥青混合料的材料组成是影响沥青混合料基灌注式半刚性路面各项性能变化的主要因素,通过对A1~A5等5种不同矿料级配组合配制空隙率为28%的基体沥青混合料性能测试、沥青混合料基灌注式半刚性路面材料的试件制备和不同矿料级配组合配制的基体沥青混合料灌注复合水泥胶浆形成的沥青混合料基灌注式半刚性路面的性能测定,试验结果表明:室内制备马歇尔试验试件时,水泥砂浆的灌入量为(500±10)g为宜,基体沥青混合料不同矿料级配组合对沥青混合料基灌注式半刚性路面各项性能影响较大,A4矿料级配组合配制的沥青混合料基灌注式半刚性路面综合性能最佳。该结果为沥青混合料基灌注式半刚性路面室内试验和工程施工应用提供依据。
Asphalt Mixture Basis-Pouring Semi-Rigid Pavement is composed of matrix asphalt mixture and grouting composite cement mortar. The material composition of matrix asphalt mixture is the main factor affecting the performance change of semi-rigid pavement , Through the combination of A1 ~ A5 and other five kinds of mineral gradation preparation of 28% porosity of the matrix asphalt mixture performance testing, asphalt mixture-based semi-rigid perfusion material specimen preparation and grading different mineral mix The test results show that when the Marshall test specimen is prepared indoors, the infiltration of cement mortar is (500 ± 10) g / g is appropriate, the combination of different mineral aggregate gradation has a great influence on the performance of asphalt semi-rigid perfusion road. The comprehensive performance of semi-rigid asphalt pavement based on A4 aggregate gradation optimal. The results provide basis for indoor test and engineering application of asphalt mixture based semi-rigid perfusion road.
