Abstract

Flexible pavements are chosen specially in the high temperature gradient for construction of roads. However, increased volume of traffic, overloading and world climatic changes, have caused widespread problems with the performance of these pavements. On the other hand, the huge amount of polymer is being produced causing menace to the environment. Recycling the waste polymers and using it in road construction have also considerable environmental benefits, such as reduced need for landfill, less pollution of both air and water. The present study was carried out on recycled and virgin polymers with two different sizes (granulate and flour); polyethylene low density (LDPER & V), highdensity polyethylene (HDPER & V), ethylene-vinyl acetate (EVAR & V) were used for modification of pristine bitumen (VG- 30). The outcome of the laboratory standard tests (conventional characterization, storage stability, dynamic viscosity, and resilience) were used in order to choose best-recycled polymer materials and their production. After comprehensive investigations, it has been found that optimum dosage of modified binder with virgin and recycled EVA and LDPE are 3% and 5% by weight, respectively. In case of recycled HDPE, the 3% was determined as an optimum dosage of modifier while for virgin HDPE it is 5%.
