Article Preview

Two-dimension finite difference time domain (FDTD) update equations are established, and the GPR electromagnetic wave propagation in rigid pavement with voids beneath slabs is numerical simulated by using effective CPML boundary conditions, and then the two-Dimension GPR images for voids beneath slab are obtained. Moreover, the relationship between characteristics of voids beneath rigid slabs and GPR data is analyzed. The achievements of this paper will provide a theoretical basis for the use of GPR to rapidly detect voids beneath rigid slab.
