Ground penetrating radar (GPR) is a key tool in pavement engineering studies. GPR provides unique information on pavement construction, layer thickness and defects. GPR can also significantly enhance the information obtained from other survey methods such as deflectograph measurements and falling weight deflectometer (FWD) tests.
