Abstract :Timely and cost effective maintenance activities are required to perform well under changing climatic conditions during service life of a hot mix asphalt (HMA) pavement. Pavement maintenance and rehabilitation process plays an important role for cost-effective pavement life cycle. Nondestructive testing methods provide to getting significant and rapidly information about the pavement without causing any damage on the surface of the pavement. In this paper, for early detection of delamination of asphalt surface layers, the results of extensive tests performed with deflection-based and seismic-based nondestructive devices are presented. The technologies in this field are briefly overviewed and obtained results are compared from various aspects.Keywords : Pavement, delamination, deflection based methods, seismic methods
