Abstract

The invention discloses a cracking treatment method of a semi-rigid base asphalt pavement, which adopts a crack comprehensive tester to detect the crack width and the crack depth of the cracks to be tested of the semi-rigid base asphalt pavement. The ground penetrating radar GPR detection is used to obtain the detection results of each structural layer in the semi-rigid base asphalt pavement, so as to realize the rapid detection of the semi-rigid pavement disease in an all-round way. In addition, the crack width, the crack depth and the detection result are combined to divide the cracks to bemeasured into cracking types; Secondly, the causes of cracking diseases of cracks to be measured are analyzed. Based on the corresponding structural hierarchy of the cracks to be measured and the causes of the cracks, the corresponding prevention and treatment of the cracks to be measured in each cracking type are carried out.

Description

technical field [0001] The present application relates to the technical field of road surface maintenance and repair, in particular to a method for treating cracking of semi-rigid base asphalt pavement. Background technique [0002] In recent years, with the rapid development of my country's high-grade highway construction, the traffic road network is becoming more and more perfect, and the focus of highway construction is gradually developing from large-scale new construction to maintenance, maintenance and reconstruction. Among them, the semi-rigid pavement is composed of cement, lime and other inorganic binders to stabilize the base layer and the asphalt surface layer. Because of its high strength, large bearing capacity, and good integrity, it has been widely used in high-grade highway construction. However, semi-rigid pavement has various degrees of damage after it has been opened to traffic for a period of time, such as cracks, pumping, subsidence, voids, potholes, etc...
