摘　　要：为考查建筑垃圾再生集料作为公路基层建筑材料的可行性,以不同废砖含量的建筑垃圾再生集料替代全部粗集料,研究了石灰粉煤灰稳定建筑垃圾再生集料的抗压强度、水稳定性和抗冻性能等路用性能。结果表明当废砖再生集料掺量不大于40%时,混合料的强度和各项性能满足公路底基层及二级以下公路重交通基层的要求,可以作为这些公路的建筑材料。In order to investigate the feasibility of construction waste recycled aggregate as highway base construc-tion materials,all coarse aggregates are replaced by construction waste recycled aggregates with different contents of waste brick,the compressive strength,water stability and frost resistance of lime fly ash stabilized recycled aggregate from construction waste were studied.The results show that the strength and other properties of the mixture can meet the requirements of highway sub-base and the Grade II and below highway heavy traffic base while the content of waste brick recycled aggregate is not more than 40%.It can be used as the construction materials of highway with these grades.
