Investigation of the factors affecting the deterioration of local road infrastructure

The investigation of the main factors affecting pavement deterioration is of paramount importance as by effectively addressing the causes, remedial measures can be initiated to control the early pavement deterioration in the local road network. It has been found that the major causes of pavement deterioration are structural factors which are interlinked with excessive traffic and loading. Moreover, the sub soil factors and drainage conditions also affect the pavement condition considerably. The concept of Remaining Service Life is used for prediction of the residual time for which a pavement section will remain serviceable. The trends of the distress types propagation, Pavement Condition Index and Remaining Service Life gives prediction about the future state of pavement deterioration. Now a days most of the highway authorities are using Falling Weight Deflectometer for the evaluation of the structural capacity of the pavement sections which can be further used to devise the rehabilitation strategies and ultimately funding requirements for maintaining roads in optimum condition.
