FLEXIBLE PAVEMENT REHABILITATION SH177 (CH: 0.00 TO CH: 9.00) VYARA JUNCTION TO ANUMALA JUNCTION

Abstract

The evaluation of a functional behavior or performance analysis, information is needed on the history of riding quality of the pavement stretch. In condition survey, pavement surface condition is measured and which types of the distress is observed. For the subgrade evaluation soil sample is taken at required locations on road stretch. In the structural evaluation of flexible pavement the pavement deflection is measured by the Benkelman Beam. It is possible to measure the rebound and residual deflections of the pavement structure. While the rebound deflection is one related to pavement performance, the residual deflection may be due to non-recoverable deflection of the pavement or because of the influence of the deflection bowl on the front legs of the beam. Rebound deflection is used for overlay design. A detailed pavement condition survey is done on State Highway 177 (Vyara Junction to Anumala Junction) and the road condition is evaluated structurally. The present study is evaluates the overlay thickness for State Highway 177 Vyara Junction to Anumala Junction.
