再生骨料在透水铺装路面中的应用研究

Research on the Application of Recycled Aggregate in Permeable Pavement

以不同掺量的再生骨料制备再生透水路面,并进行表观密度、透水系数、抗压强度和抗折强度性能试验。试验结果表明:增加再生骨料掺量会削减再生混凝土的抗压强度和抗折强度,但对透水系数具有增益效果,其中透水系数的波动幅度受再生骨料掺量变化影响最大。综合各性能对比分析结果,建议再生透水混凝土路面采用的再生骨料掺量为40%。

The recycled permeable pavement is prepared by the recycled aggregate with different mixing amounts,and the tests on the apparent density,permeability coefficient,compressive strength and flexural strength performance are carried out.The test results show that:increasing the mixing amount of recycled aggregate will reduce the compressive strength and flexural strength of recycled concrete,but it will have a gain effect on the permeability coefficient,and the fluctuation amplitude of the permeability coefficient is most affected by the change of the mixing amount of recycled aggregate.Based on the comparative analysis results of various properties,it is suggested that the mixing amount of recycled aggregate used in the recycled permeable concrete pavement is 40%.
