Most important, is the capability to quickly gather data at several locations while keeping a runway, The DCP test indicates the shear strength of the material based on the measurement of the rate of penetration. Seismic methods have also been proved useful for field testing of pavements (e.g Nazarian et al., 1654), because the elastic modulus, the shear modulus and the Poisson's ratio can be calculated without any empirical correlation from the seismic velocities (P-wave and S-wave velocities). The ability to do more pavement testing using nondestructive methods can simplify the process and make some data collection more routine. But the problem tat is usually faced with this tecknology is that great number of persons affiliated with road construction practices, are not well aware with the procedure for conducting these tests and the correct enterpretation of the data so obtained.
