Abstract

The main task of present evaluation work is to conduct pavement performance evaluation of roads which is constructed using Zydex nanotechnology under the technology demonstration project of Namma Grama Namma Raste Yojane (NGNRY) under KRRDA, in Chitradurga and Tumkur District in Karnataka. The purpose of the work is to conduct pavement performance studies on roads which consist of structural and functional evaluations and Geotechnical Investigation (Grain Size Analysis, Atterberg Limits and CBR). The road stretch is evaluated by MERLIN (Roughness evaluation) and pavement condition survey. Detailed survey has been carried out on roads. Road inventory survey includes visual observation, soil characteristics and shoulder condition survey. Severity of potholes, area of patching, cracking of bituminous layer, percentage of raveling, longitudinal depression, rut depth has been measured during condition survey of the pavement. The test were carried out on 5 different roads in Karnataka incorporated with zydex nano technology materials, all the roads were free from pavement distresses, structural conditions of the pavement was good and roughness value shows less significance on vehicle operation cost.
