Method and system for pavement construction quality inspection

Abstract

The invention discloses a pavement construction quality detecting method and system. The system comprises a three-dimensional ground penetrating radar, a non-nuclear density gauge and a data processing device. The method comprises the steps that first density data corresponding to a pavement are obtained through calculation according to a pavement dielectric constant obtained by measuring of the three-dimensional ground penetrating radar; a pavement density color map is drawn and generated according to the first density data; a pavement density grey-scale map is drawn and generated according to second density data obtained by the non-nuclear density gauge; and consistency judgment is conducted on the pavement density color map and the pavement density grey-scale map. By means of the pavement construction quality detecting method and system, the construction quality of a newly-built pavement can be quickly and accurately evaluated in time, and thus corresponding instructions are provided for later construction of a construction unit to improve the pavement construction quality. The pavement construction quality detecting method and system can be widely applied to the field of road construction engineering.

Description

technical field [0001] The invention relates to road engineering detection technology, in particular to a road construction quality detection method and system based on a three-dimensional ground penetrating radar and a non-nuclear density meter. Background technique [0002] In the highway road engineering quality inspection and evaluation standards, the flatness and deflection value of the pavement surface are listed as important indicators for evaluating the quality of high-grade highway asphalt pavement. How to quickly and objectively detect and evaluate various indicators of the road surface has long been one of the key concerns of the construction department and the quality management department. [0003] At present in this field, to the quality detection and evaluation of road pavement, the traditional method that it adopts is the core sampling method, and the current method that adopts then comprises the pavement quality detection technology that combines the core sa...
