摘　　要：为解决建筑垃圾“垃圾围城现象”,推动建筑垃圾资源化利用,将建筑垃圾再生骨料无机结合料用于道路结构的基层和底基层中,为验证其修建的路面基层具有足够的强度、刚度和稳定性,设计了几组不同配合比的石灰粉煤灰稳定再生材料、水泥粉煤灰稳定再生材料对其力学性能、稳定性和耐久性路用性能进行评价。推荐配合比为石灰:粉煤灰:再生砖石=7:13:80并外掺1%水泥和3:6:91水泥粉煤灰再生砖石。In order to solve the"garbage siege phenomenon"of construction waste and promote the utilization of construction waste resources,the recycled aggregate inorganic binder of construction waste is used in the base and subbase of road structure.In order to verify that the pavement base built by recycled aggregate inorganic mixture has sufficient strength,stiffness and stability,several groups of lime fly ash and cement fly ash stable recycled ma⁃terials with different mix ratios were designed.The mechanical properties,stability performance and durability of lime-ash&cement fly ash stabilized regenerated were evaluated.It was concluded that the comprehensive road per⁃formance mixture ratio of lime:fly ash:recycled brick=7:13:80 with 1%cement and 3:6:91 cement fly ash stabi⁃lized regenerated brick.
