T/GXGS 01-2026 Three-dimensional ground-penetrating radar detection technical specification for hidden defects in roads
Basic Information
Scope
This document specifies the terms and definitions, basic requirements, classification and requirements of detection items, detection systems, detection methods and processes, and requirements for detection results of three-dimensional ground-penetrating radar (GPR) detection of hidden defects in roads within the administrative area of Guangxi Zhuang Autonomous Region. This document is applicable to the detection of hidden defects in road subgrades and pavements, or within or between layers of the subgrade, using three-dimensional GPR in urban roads within the administrative area of Guangxi Zhuang Autonomous Region. The detection of hidden defects in roads in other areas, such as highways, factory areas, airports, and docks, can be used for reference. The hidden defects referred to in this document include loose soil, voids, cavities, and other types of defects within the detection depth range of three-dimensional GPR in road subgrades and pavements.
