In order to study the applicability of recycled aggregate in hydraulic asphalt concrete, the mix proportion test of recycled aggregate hydraulic asphalt concrete was carried out, and its mix proportion parameters were determined through uniaxial compression, splitting test and permeability (porosity). The asphalt aggregate ratio is 7.0%, the grading index is 0.37, the filler content is 13%, and the replacement rate of recycled aggregate is 50%. The recycled aggregate was modified with modifiers of different concentrations. The water absorption, apparent density, crushing index and adhesion of the recycled aggregate were analyzed to determine the modifier concentration that meets the test requirements. The modifier concentration in this test is 10% of water glass and 12% of silane coupling agent. Based on the above research, the applicability of recycled aggregate in hydraulic asphalt concrete was studied through water stability coefficient, thermal stability coefficient and permeability coefficient. The results show that the application of recycled aggregate in hydraulic asphalt concrete can meet the requirements of the specification, which can provide a reference for the popularization and application of recycled aggregate in hydraulic asphalt concrete.

为研究再生骨料在水工沥青混凝土中的适用性,对再生骨料水工沥青混凝土进行了配合比试验,并通过单轴压缩、劈裂试验、防渗性(孔隙率)确定其配合比为油石比7.0%、级配指数0.37、填料含量13%、再生骨料替代率50%。对再生骨料采用不同浓度的改性剂进行改性,分析再生骨料的吸水率、表观密度、压碎指标、粘附性,确定满足试验要求的改性剂浓度为水玻璃的浓度10%、硅烷偶联剂的浓度12%。在此基础上通过水稳定系数、热稳定系数、渗透系数研究了再生骨料在水工沥青混凝土中的适用性。结果表明,再生骨料应用于水工沥青混凝土中能够满足规范要求,可为再生骨料在水工沥青混凝土中推广应用提供参考。

为研究再生骨料在水工沥青混凝土中的适用性,对再生骨料水工沥青混凝土进行了配合比试验,并通过单轴压缩、劈裂试验、防渗性(孔隙率)确定其配合比为油石比7.0%、级配指数0.37、填料含量13%、再生骨料替代率50%。对再生骨料采用不同浓度的改性剂进行改性,分析再生骨料的吸水率、表观密度、压碎指标、粘附性,确定满足试验要求的改性剂浓度为水玻璃的浓度10%、硅烷偶联剂的浓度12%。在此基础上通过水稳定系数、热稳定系数、渗透系数研究了再生骨料在水工沥青混凝土中的适用性。结果表明,再生骨料应用于水工沥青混凝土中能够满足规范要求,可为再生骨料在水工沥青混凝土中推广应用提供参考。

In order to study the applicability of recycled aggregate in hydraulic asphalt concrete, the mix proportion test of recycled aggregate hydraulic asphalt concrete was carried out, and its mix proportion parameters were determined through uniaxial compression, splitting test and permeability (porosity). The asphalt aggregate ratio is 7.0%, the grading index is 0.37, the filler content is 13%, and the replacement rate of recycled aggregate is 50%. The recycled aggregate was modified with modifiers of different concentrations. The water absorption, apparent density, crushing index and adhesion of the recycled aggregate were analyzed to determine the modifier concentration that meets the test requirements. The modifier concentration in this test is 10% of water glass and 12% of silane coupling agent. Based on the above research, the applicability of recycled aggregate in hydraulic asphalt concrete was studied through water stability coefficient, thermal stability coefficient and permeability coefficient. The results show that the application of recycled aggregate in hydraulic asphalt concrete can meet the requirements of the specification, which can provide a reference for the popularization and application of recycled aggregate in hydraulic asphalt concrete.
