Application of recycled concrete aggregates (RCA) and crushed bricks (CB) into pavement materials is an ideal waste management solution. By appropriate material design, the RCA and CB could be used in permeable concrete as the pavement base which meets the principle of ‘sponge city’. This study aims to evaluate the performance of cement treated permeable concrete containing RCA and CB as the road base. Because of high-water absorption of RCA and CB leads to greater design deviations and resulted in leakage of cement slurry, the optimised volume method was used in mixture design. The compressive strength test, shrinkage test and water permeability test were performed. Results showed that the cement treated permeable concrete containing CB was an ideal fast-drying and low shrinkage due to drying material. Although CB had certain weakening effect on concrete strength, the strength of the permeable concrete was found acceptable according to the available specification. In addition, satisfied permeable performance was observed. It was recommended that concrete containing 15% of CB in weight (CB-15) was suitable to road base with moderate traffic level, and the concrete without CB (CB-0) to high traffic level, respectively. As the concept of environmental protection was being recognised by most countries in the world. This study suggested a potential direction for the large-scale application of RCA and CB.

将再生混凝土骨料 (RCA) 和碎砖 (CB) 应用于路面材料是一种理想的废物管理解决方案。通过适当的材料设计，RCA和CB可用于透水混凝土作为符合“海绵城市”原则的路面基层。本研究旨在评估含有 RCA 和 CB 作为路基的水泥处理透水混凝土的性能。由于RCA和CB的高吸水率导致较大的设计偏差并导致水泥浆泄漏，因此在混合物设计中采用了优化体积法。进行了抗压强度试验、收缩试验和透水性试验。结果表明，水泥处理的含CB透水混凝土是一种理想的快干、低干缩材料。虽然CB对混凝土强度有一定的削弱作用，但根据现有规范发现透水混凝土的强度是可以接受的。此外，观察到满意的渗透性能。建议含 15% CB 的混凝土（CB-15）分别适用于中等交通水平的路基，而不含 CB 的混凝土（CB-0）分别适用于高交通水平。随着环保理念得到世界上大多数国家的认可。该研究为RCA和CB的大规模应用提供了潜在的方向。建议含 15% CB 的混凝土（CB-15）分别适用于中等交通水平的路基，而不含 CB 的混凝土（CB-0）分别适用于高交通水平。随着环保理念得到世界上大多数国家的认可。该研究为RCA和CB的大规模应用提供了潜在的方向。建议含 15% CB 的混凝土（CB-15）分别适用于中等交通水平的路基，而不含 CB 的混凝土（CB-0）分别适用于高交通水平。随着环保理念得到世界上大多数国家的认可。该研究为RCA和CB的大规模应用提供了潜在的方向。
