convensional bitumen, high density polyethylene, crumb rubber and styrene butadiene styrene.
The increasing environmental concern about waste materials and reuse of waste materials can present benefits at an environmental and economic level, and some wastes can be used to improve the pavement performance. Thus, the different waste materials in bitumen, namely waste motor oil and different polymers for 10% of waste motor oil and 5% of polymers (high density polyethylene, crumb rubber and styrene-butadiene-styrene) were added to a conventional bitumen and the resulting modified bitumens were characterized Such improvements might indicate a good behaviour at medium or high temperatures and an increase of fatigue and rutting resistance..
