Application technology of falling weight deflectometer and ground penetrating radar in pavement construction

Abstract

The invention relates to the application of drop hammer detect radar, in the road construction, wherein the invention can laminated check the road quality and evaluate the punch effect; it can continuously check and evaluate the thickness, compression and water content of road structure layer; and the thickness checked result can be input the reveres software to improve the calculation accuracy of physic character. The invention can real-time check and evaluate the road without damaging, to control the quality and improve the service life of road.

Description

technical field [0001] The invention belongs to the non-destructive detection and evaluation technology of subgrade and pavement, and in particular relates to the application technology of drop hammer deflection meter and ground penetrating radar in the road construction process. Background technique [0002] In recent years, my country's highway construction is in a period of vigorous development, especially the construction of high-grade highways is in the ascendant. How to discover hidden dangers of engineering quality in time and control construction quality, so as to avoid premature pavement damage, improve road service life, and reduce maintenance funds have become key issues that need to be solved urgently in my country's highway construction and management. [0003] Due to the late start of expressway construction in my country, the slow development of subgrade and pavement detection and evaluation technology, and the lack of advanced detection methods and evaluation...

Problems solved by technology

But generally speaking, the research on applied theory and the development of supporting software have always lagged behind the development of high-tech testing equipment. Among them, the inversion of roadbed and pavement material properties has always hindered the development of non-destructive testing technologies such as falling weight deflectometer and ground penetrating radar.

How to apply the drop weight deflection meter and ground penetrating radar to the quality control of the road construction process, and the combination of the falling weight deflection meter and the ground penetrating radar application technology has not yet been related.
