ABSTRACT

This article aims to outline the established Ground Penetrating Radar (GPR) applications for concrete pavements that are currently under development or not yet commonly applied. GPR is a non-destructive method that detects variations in the electromagnetic properties of materials, primarily the permittivity. The principles of GPR systems operation, including signal processing and data interpretation practices, are summarized in this study to review current and future uses of GPR in concrete pavement detail analysis. The use of different approaches besides GPR, makes pavement evaluation more efficient and provides more details of the material properties. In concrete pavement structure investigations, GPR technology has been utilized to detect layer thickness and rebar properties, and it also determines subsurface defects and assesses base layer conditions. In quality control studies, GPR technology is implemented for thickness and air void content measurements. Future research may include investigating GPR technique in supporting pavement designs and repair strategies. Regardless of the benefits, several limitations are reported that prevent using this technique for pavement investigation on a broader scale. The problems associated with this procedure, such as the accuracy of the method and the difficulties in interpreting recorded signals, are discussed.

摘要

本文旨在概述目前正在开发或尚未普遍应用的混凝土路面的探地雷达 (GPR) 应用。GPR 是一种非破坏性方法，可检测材料电磁特性的变化，主要是介电常数。本研究总结了 GPR 系统操作的原理，包括信号处理和数据解释实践，以回顾 GPR 在混凝土路面细节分析中的当前和未来用途。除了 GPR 之外，使用不同的方法可以提高路面评估的效率，并提供更多材料特性的详细信息。在混凝土路面结构调查中，探地雷达技术已被用于检测层厚和钢筋性能，它还可以确定表面下的缺陷并评估基层状况。在质量控制研究中，GPR 技术用于厚度和空气空隙率测量。未来的研究可能包括调查探地雷达技术在支持路面设计和修复策略方面的作用。不管好处如何，据报道存在一些限制，这些限制阻止了将这种技术用于更广泛的路面调查。讨论了与此过程相关的问题，例如方法的准确性和解释记录信号的困难。据报道，一些限制阻止了在更广泛的范围内使用这种技术进行路面调查。讨论了与此过程相关的问题，例如方法的准确性和解释记录信号的困难。据报道，一些限制阻止了在更广泛的范围内使用这种技术进行路面调查。讨论了与此过程相关的问题，例如方法的准确性和解释记录信号的困难。
