Application of MHB Technique in Superhighway Cement Concrete Pavement Resurfacing Projects

Abstract

MHB technique is applied, in superhighway cement concrete pavement resurfacing project (“white to black” project in short), to break the pavement surface and build the new pavement taking the broken one as the base or subbase, which makes good use of the remains in a very economical and environmentally friendly way, and solves the problem of reflective cracks appearing on the pavement surface after reconstruction as well. This thesis confirms the relevant parameters of MHB construction machinery, construction quality and intensity testing, etc by making researches in test sections, discusses the key process in construction with MHB technique and the relevant quality control measures during construction, and puts forward the ideas of reconstructing the pavement with MHB technique while making no influence on the superhighway traffic, even when the traffic if heavy.
