Title

White Topping As A Rehabilitation Alternative For Bituminous Road

Abstract

Use of concrete overlay as a rehabilitation measure for strengthening of deteriorated bituminous pavements is increasing. This concept has so far not found significant applications in the country. This is one of the rehabilitation method which results in lower maintenance cost. This method of rehabilitation/strengthening can be adopted for rural road network and district roads as these roads have low to moderate traffic. Even on the State Highways and some recently declared National Highways, where traffic is moderate, the above method of strengthening has a lot of promise. By adopting whitetopping, a large network of roads can be rehabilitated at reasonable costs and these rehabilitated roads will have an improved lifespan than conventional flexible pavements. In the present work, an attempt is made to evaluate the structural and functional condition of the existing flexible pavements and provide a cost effective rehabilitation solution. A network of five low volume roads coming under Pune District was selected and extensive field, laboratory investigation, pavement analysis and design of rehabilitation alternative were carried out. The field work consists of road inventory, traffic studies, Bump Integrator and BBD studies. PCI was computed based on the selected distress parameters i.e., rut, patch, pothole, cracks. In addition, IRI and characteristic pavement deflections were computed from Bump Integrator and BBD surveys. Based on PCI, IRI and deflection values pavement rehabilitation measures were considered. The summary of overall condition assessment on functional and structural evaluation in majority of the cases resulted in 3 resurfacing and 1 overlay. In the present study, an attempt was made to design concrete overlay section and asphalt overlay as a rehabilitation alternative for the in-service flexible pavements. The concrete overlay design resulted in four 200mm thickness sections. Strengthening by asphalt overlay resulted in different overlay thicknesses for the selected roads. Finally cost comparison between concrete and asphalt overlay reveals that for majority of selected roads concrete overlay proves to be a cost effective rehabilitation solution than the asphalt overlay.
