%X This paper discusses the detection of concealed cracks under highway surface.We described the ground penetrating radar method and the numerical and physical modeling results of the effects of vertical cracks on GPR wavefield in horizontally layered homogeneous media.Comparisons show that the modeling results are in good agreement with those from project examination.Both theoretical study and practice prove that detection of concealed cracks in highway structural layers with GPR is correct in theory and feasible in practice.
