Identification of Ballast Fouling Status and Mechanized Cleaning Efficiency Using FDTD Method

Systematic assessment of ballast fouling and mechanized cleaning efficiency through ground penetrating radar (GPR) is vital to ensure track stability and safe train transportation. Nevertheless, conventional methods of ballast fouling inspection and evaluation impede construction progress and escala...
