Design of Rehabilitation Treatments for Highway Pavements Considering Life Cycle Cost Analysis

The highway pavements are subjected to increased magnitude of traffic load repetitions and they require frequent resurfacing and rehabilitation treatments during the design life. Falling Weight Deflectometer (FWD) is used for the structural condition evaluation of pavements. Deflection bowl parameters like Base Layer Index, Middle Layer Index, and Lower Layer Index can be used to study the contribution of the different pavement layers on the performance. The computed deflection bowl parameters can be related to the field performance quantified in terms of rutting and cracking. These deflection bowl parameters are to be bench-marked for Indian conditions based on performance from in-service highway pavements, so that the pavement sections may be grouped as sound, warning or severe condition and to estimate the remaining service life and the optimal timing for the resurfacing and rehabilitation treatments. The rehabilitation treatments are conventionally decided based on initial construction cost. However, cost-effective rehabilitation treatments duly considering Life Cycle Cost (LCC) is the need of the hour. The present paper is an attempt in this direction on evaluation of a typical National Highway pavement using FWD bowl data, bench-marking of deflection bowl parameters for Indian conditions and design of cost- effective alternate maintenance and rehabilitation treatments duly considering the life cycle cost.
