Polymer Bitumen for pavements designed and constructed for heavy duty traffic and extreme weather conditions require specially designed and engineered bitumen grades.
However, by changing the characteristics of normal bitumen with the addition of a polymer, either they are of elastomeric nature or elastomeric. Meanwhile we succeed to obtain bitumen that allow the mixture to be more cohesive. With much more strength and significant higher resistance to parameters like fatigue and permanent deformations for road pavements.
