摘要
以长张高速公路益常段旧水泥混凝土路面改造工程为依托,简述旧水泥混凝土路面碎石化技术;通过建立计算模型,比较共振碎石化、多锤头碎石化及冲击破裂稳固3种破碎(破裂)情况下加铺沥青层结构的加铺层层底拉应力及相对弯沉比情况,表明共振破碎后原路基整体强度优于多锤头碎石化技术。
Based on Yiyang-Changde freeway pavement reconstruction project,the comparison of the surface deflections and the tensile stresses for different asphalt overlay structures on the rubblized Portland Concrete Cement（PCC）pavement by means of Multi-Head Breaker（MHB）,Resonant Pavement Breaker（RPB）and broken-seated techniques shows that the RPB is better than the MHB.
