旧水泥路面多锤头与共振碎石化技术特点研究

Research on Technical Characteristics of Multi-hammer and Resonance Crushing of Old Cement Pavement

总结分析了水泥混凝土路面大修过程中为防止反射裂缝对原路面进行离散化的原则,阐述了采用传统方法对旧水泥路面进行维修养护的缺陷,并进一步探讨了碎石化后结构层的力学特性及效果评价指标。通过对多锤头碎石化和共振碎石化二者的技术特点以及适用条件进行研究,提出了合适的碎石化方案。

This paper summarizes and analyzes the discretization principle for the original pavement in order to prevent reflection cracks during the overhaul of cement concrete pavement,expounds the defects of using traditional methods to maintain the old cement pavement,and further discusses the mechanical characteristics and the evaluation index of the structural layer after crushing.By studying the technical characteristics and applicable conditions of multi-hammer crushing and resonance crushing,a suitable crushing scheme is put forward.
