旧水泥混凝土路面改造方式的选择

Selection of Reconstruction Methods of Old Cement Concrete Pavement

旧水泥混凝土路面改造主要有板块加固后加铺、打裂压稳、冲击压裂、多锤头碎石化、共振碎石化、翻挖板块后重建等6种方式,实践中多凭工程技术人员的主观经验判断以选择最优的改造方式,从而造成误判的可能性较大。针对这个问题,在路况指标的遴选、阈值的确定等基础上,提出了不同旧水泥混凝土路面改造方式对应的具体路况指标,可较为准确、方便地确定旧水泥混凝土路面的改造方式,供相关人员参考。

The reconstruction of old cement concrete pavement mainly includes six ways:paving after plate reinforcement,cracking and stabilizing,impact fracturing,multi hammer crushing,resonance crushing,and reconstruction after plate excavation.In practice,it is mostly judged by the subjective experience of engineers and technicians to select the optimal reconstruction method,which is more likely to cause misjudgment.Aiming at this problem,based on the selection of road condition indicators and the determination of threshold,the specific road condition indicators corresponding to different old cement concrete pavement reconstruction methods are put forward,which can accurately and conveniently determine the reconstruction methods of old cement concrete pavement and provide reference for relevant personnel.
