摘　　要：通过对再生骨料透水混凝土、透水混凝土、普通混凝土的工作性能和力学性能的试验分析,重点研究再生骨料透水混凝土、透水混凝土的收缩性和抗冻性。试验结果表明:再生骨料透水混凝土的收缩变形最大,透水混凝土的收缩变形次之,普通混凝土的收缩变形最小。透水混凝土和再生骨料透水混凝土25次冻融循环后的抗压强度损失不大于20%,质量损失不大于5%,满足无砂水泥透水混凝土的抗冻性指标要求。Working performance and mechanical performance of the recycled aggregates of pervious concrete, pervious concrete and ordinary concrete were analyzed by test. On this basis, shrinkage and freeze resistance of the recycled aggregates of pervious concrete, pervious concrete were mainly studied. The test results showed that the recycled aggregates of the pervious concrete contraction deformation was the largest one, the pervious concrete deformation was larger, and normal concrete deformation was minimal. After 25 freeze-thaw cycles of pervious and recycled aggregate pervious concrete,the compressive strength loss was less than 20% , the quality loss was less than 5% , which could meet the requirement for no sand cement pervious concrete frost resistance index.
