Wang, Shilei (author), Liu, Guixian (author), Jing, Guoqing (author), Feng, Qiankuan (author), Liu, Hengbai (author), Guo, Y. (author)In the past 20 years, many studies have been performed on ballast layer inspection and condition evaluation with ground penetrating radar (GPR). GPR is a non-destructive means that can reflect the ballast layer condition (fouling, moisture) by analysing the received signal variation. Even though GPR detection/inspection for ballast layers has...review 2022

Guo, Y. (author), Liu, Guixian (author), Jing, Guoqing (author), Qu, Jianjun (author), Wang, Shilei (author), Qiang, Weile (author)Ground penetrating radar (GPR) has been applied for ballast layer inspection for two decades, mainly for the analysis of ballast layer fouling levels. However, some issues that affect the inspection quality remain unsolved, such as issues involving the GPR equipment quality (antenna) and the correlation between the GPR indicator and fouling...journal article 2022
