Abstract
In India, different types of pavement design have been observed. Most of the
highways are having the flexible pavement. Pavement is designed to support the wheel
load imposed on it from traffic moving over it. Additional stresses are also imposed by
change in the climate. Pavement should be strong enough to resist the stresses and to
distribute the external load. The study highlights the need of pavement evaluation and
pavement evaluation measures for the road pavements of Road joining NH48 to NH548.
Present study also 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 and laboratory investigations, and finally on the basis
of data analysis, design of extra width of road and overlay thickness of the road pavement
and strengthening of the pavement has been discussed for the same road stretch.
For road widening the existing traffic volume study carried out and compared with
design standard volume as per IRC: 64-1990 guidelines and need of widening is justified.
For structural evaluation the existing pavement condition has carried out by BBD
technique and overlay design has carried out as per IRC: 81-1997 guidelines.
