Embodiment Construction

[0032] Such as figure 1 Shown, a kind of road quality detection method based on FWD and 3D ground penetrating radar, the steps that this method includes are:

[0033] Use FWD to detect the deflection of the lane, so as to obtain the deflection data of the lane;

[0034] The ground penetrating radar is used to detect the lane, so as to obtain the ground penetrating radar image of the lane;

[0035] find deflection data greater than a threshold value from the acquired deflection data;

[0036] Analyze and process the obtained ground-penetrating radar images, so as to find out road defects in the ground-penetrating radar images;

[0037] Make a consistency judgment on the point corresponding to the found deflection data and the road disease, so that the deflection data can be used to

[0038] Verification of road damage.

[0039] Such as figure 2 As shown, the road quality detection system based on FWD and 3D ground penetrating radar corresponding to the above method includ...

Abstract

The invention discloses a road quality detection method and system based on a FWD (Falling Weight Deflectometer) and a 3D ground penetrating radar. The system comprises the FWD, the ground penetrating radar and a data processing device. The method comprises the following steps: finding deflection data greater than a threshold from acquired deflection data; performing analytical processing on the acquired ground penetrating radar image so as to find road diseases in the ground penetrating radar image; and performing consistency judgment on sites corresponding to the found deflection data and the road diseases. According to the method and system disclosed by the invention, the road diseases can be timely found, the road is accurately cured and maintained, the method and system have significances for preventing the road from being early damaged, delaying overhauling and prolonging the service life of the road, and an important basis and a technical support can be provided for old road reconstruction and maintenance and overhauling. The road quality detection method and system based on the FWD and the 3D ground penetrating radar disclosed by the invention can be widely applied to the field of road engineering.

Description

technical field [0001] The invention relates to road engineering technology, in particular to a road quality detection method and system based on FWD and 3D ground penetrating radar. Background technique [0002] Explanation of technical terms: [0003] FWD: Falling Weight Deflectometer. [0004] 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. [0005] At present, in this field, the traditional method used for pavement detection and evaluation of highways is the core sampling method, while the currently used methods include the detection and evaluation method combined with the core sampling me...
