A Hill road is one which passes through a terrain with a cross slope of twenty five percent or more. A hilly or Mountainous area is characterized by a highly broken relief with widely differing elevations, steep slopes, deep gorges and a great number of water courses. Owing to complex topography, the route has to be ineffectively increased. Flexible pavements are especially affected by moving vehicles, as a result of moving vehicles the pavement starts deteriorate. The existing road has been badly damaged due to heavy intensity of rain and by the due course of time. The main objectives of this project involve widening of the existing road up to the desirable limit and to renovate the pavement where the roads have been heavily damaged. The results indicate that the Benkelman beam method was used for the calculation of the deflection behavior against dynamic vehicle loading for flexible pavements.
