An Investigation on Remaining Service Life of Rural Roads

Abstract

Low-volume roads not only account for a major portion of national road networks, but also play a very vital role in the socio economic growth of a country like India whose 75 percent of population lives in villages. India has the second largest network in the world. Till now, low-volume roads in India are basically low cost roads having low grade specifications. During the last 8-10 years the maintenance discussion of these road based on ad-hoc experience of engineers. So it has been felt that the performance of these roads is monitoring and scientific based discussion making tools are estimates. The present study focus on estimating the remaining service life (RSL) using the performance indicators such as traffic, rutdepth skid number and deflection data. Detailed analysis has been done to asses performance of these roads and suitable responsive models have been developed.
