| Abstract: | The causes and features of void under road surface in cement concrete pavement of rural highway are analyzed by investigating the damage of cement concrete pavement of several rural highways.Response modulus of base course top in middle part and side of the pavement are back calculated by theoretical regression method and void status of cement concrete pavement is defined by comparison.This method is verified at the field. |
