Roads are usually constructed with different layers of thickness on the basis of traffic load repetitions as well as environmental considerations. Durability and longevity of roads are the key factors for the industrial and the economic growth of a country. Hence it is necessary to evaluate the existing roads in terms of their layer thickness and strengths related to California Bearing Ratio (CBR).One of the most popular & simpler device to evaluate the road pavement in terms of their layer thickness and strengths is Dynamic Cone Penetrometer (DCP). DCP maintains ahigher degree of accuracy in theresult. Also, its operation is easier than other expensive &time-consuming devices. This paper reports a laboratory fabrication of DCP using locally available materials and validated for the investigation. The investigation includes the evaluation of existing road pavement performance in terms of their layer thickness and strength. From this investigation, it has been found that most of the existing pavements in the study area do not fulfill the design specifications. Finally, the results have been compared with the specifications given by a standard organization and a computational method.
