| Abstract | ||
| Bitumen is always used as binder road construction material, and it is extracted from petroleum purification processes. the increased in traffic density on roads, overloading of commercial vehicles and temperature variance in pavements leads to formation of different distresses like rutting, bleeding and bituminous surfacing cracking. Thus, the researchers applied various techniques to enhance the overall performance of asphalt pavement by using different types of additives. This study aims to discuss the application of high density polyethylene (PE100) and crumb rubber powder in asphalt concrete mixtures. The use of polymers offers improved drainage control and presents a better cost because of avoiding fibrous materials using in bituminous mixtures. Previous results demonstrated that the asphalt mixture modified with polymer (HDPE) enhanced rutting resistance while also improving rigidity and tensile strength. Moreover, the best concentration of HDPE in the concrete asphalt mixture was from 2% to 6% by weight of bitumen. Crumb rubber powder positively influences on rutting resistance, tensile strength, and fatigue resistance in asphalt pavement. The recommended concentration for adding Crumb rubber powder is 5-15% by weight of bitumen. Finally, adding single additives to asphalt pavement is not enough to enhance the bituminous pavement performance. Previously, some researches have been performed for improving PE flexibility using normal rubber, recovered rubber and Styrene-butadiene rubber. Therefore, it is recommended to use the admixture of HDPE and CRP in flexible pavement | ||
