EVALUATION AND STRENGTHENING OF RECONSTRUCTED ROADS EXCAVATED FOR UTILITIES USING BENKELMAN BEAM DEFLECTION (BBD) TECHNIQUE (A CASE STUDY)

The study highlights the need of pavement evaluation and pavement evaluation measures for the road pavements of urban areas in Kashmir which are often being cut and refilled after laying of utilities like optical fiber cables,municipal water supply pipes, construction of severs etc. This paper includes the collection of required field data like soil subgrade data, existing pavement structure, traffic data, pavement surface condition and rebound deflection by using BBD technique, laboratory investigations and finally the design of the overall thickness of the road pavement and overlay whatsoever required to strengthen the road stretches. This paper also includes the comparison between newly proposed thicknesses and existing ones.
