Abstract:

 Road transportation constitutes a major portion in the overall transportation system. With the increase in traffic volume, there is observatory increase in the distress of pavement structure, which in turn causes excessive deterioration. With time, the failure goes on increasing gradually due to overloading of axles and significant variations in daily and seasonal temperature of pavement which is responsible for early development of distress symptoms like potholes, rutting, cracks, and undulations in bituminous surfacing. Thus the evaluation of the condition of pavement becomes quite necessary to choose appropriate improvement technique that can be implemented to improve the quality and strength of the pavement structure. This paper presents a case study on structural and functional evaluation of flexible pavement and analyzes the condition of the pavement which includes relevant data like soil sub grade data, existing pavement structure, traffic data, laboratory investigations, rebound deflection by using BBD technique and finally the design of the overall thickness of the pavement and overlay, required to strengthen the pavement. The paper also includes comparison between the existing and the newly designed pavement thickness. Conclusions are also drawn from the overall study conducted on the road stretches followed by some useful recommendations.
