depletion of natural resources, such as natural aggregate and bitumen binder. In the current
study, to increase the workability of RAP asphalt mixtures, a softer-graded polymer
modifiedbitumen(PMB)wasproducedwitha7%styrene-butadiene-styrene(SBS)copolymer.

warranted technique to recycle the Reclaimed asphalt pavement (RAP) in making the flexible
pavements. A thorough laboratory analysis has been carried out to evaluate the effectiveness
of the changed mixture. The results of the primary tests, such as those for penetration,
softening points, viscosity, and others, will show that the previously mentioned mixture
performs significantly better than the normal mix.
