摘   要：为研究废弃混凝土与废弃砖再生骨料作为轻交通量公路基层材料时水泥稳定建筑垃圾再生骨料混合料的路用性能，进行了不同龄期的无侧限抗压强度试验、劈裂抗拉试验和抗压回弹模量试验，分析了不同骨料配合比、不同水泥用量对水泥稳定建筑垃圾再生骨料混合料的基本力学性能的影响。结果表明，不同龄期的无侧限抗压强度、劈裂抗拉强度以及抗压回弹模量受骨料种类和掺入量的影响较大，掺入混凝土再生骨料含量越多，其混合料强度就较高；含砖量越大，强度越低，但仍能满足现行规范中对基层路用性能的要求。同一种类骨料，水泥用量越高，7 d无侧限抗压强度、劈裂抗拉强度以及抗压回弹模量也越大。水泥用量的增加可提高混合料的无侧限抗压强度，但高含量的废弃砖会降低其强度。

Abstract: In order to study the road performance of cement stabilized construction waste recycled aggregate mixture when waste concrete and waste brick recycled aggregate are used as light traffic highway base material, unconfined compressive strength tests, splitting tensile tests and compressive resilience modulus tests are carried out. The effects of different aggregate mix proportion and different cement contents on the basic mechanical properties of cement stabilized construction waste recycled aggregates are analyzed. The results show that the unconfined compressive strength, splitting tensile strength and compressive resilience modulus at different ages are greatly affected by the type and amount of aggregate. The more the content of recycled aggregate, the higher strength of the mixture; the larger the brick content, the lower the strength, but which still meets the current specifications of the road performance requirements. The same type of aggregate, the higher the cement content, the greater 7 d unconfined compressive strength, splitting tensile strength and compressive rebound modulus. The increase of cement content can increase the unconfined compressive strength of the mixture, but the high content of waste brick can reduce its strength.
