Pavements designed and constructed for heavy duty traffic and extreme weather conditions require specially designed and engineered bitumen grades. By enchancing the characteristics of normal bitumen grades. By enhancing the characteristics of normal bitumen with the addition of a polymer we succeed to obtani modified bitumen that allows the mixture to be more cohesive, with much more strenght and significant higher resistance to parameters like fatigue and permanent deformations for road pavements. PMBs have been successfully used for several decades in the road industry.
