Introduction

In any country, road network is the backbone of national development. India has about 4.3 million kilometer of road network which is one of the largest network in the world. This road network is carrying 85% of passenger and 65% of freight traffic. This large road network requires a huge amount to keep road network in good condition for passenger comfort and to minimize the loss in Vehicle Operating Cost. But, in case of National Highway, funds allocated for maintenance is only 60% of its requirement. Hence it becomes necessary that the prioritization of the road sector must be done on the basis of prediction of pavement performance so that requirement of fund may be projected well in advance and the available fund be utilized properly.

Carrying out the pavement performance for flexible pavement which will be useful in developing pavement performance models.
Develop Combined Pavement Condition Prediction Index (CPCI) for flexible pavement.
Develop correlation between CPCI and age.
