Ihe siri ike na elu-elastic gbanwetụrụ bitumen bụ bitumen pụrụ iche agbanwere na-ejikọta ya na kemịkalụ nwere ezigbo netwọk agbanweela akụkụ atọ. Ebe ọ na-eme ka ọ dị nro ruru n'elu 85 Celsius C na viscosity ike ya ruru n'elu 580,000 Pa·s. Ọ bụ bitumen a na-agbanwe agbanwe nke ukwuu. The ike viscosity bụ ugboro 3 nke bitumen gbanwetụrụ ma nwee ọmarịcha ọrụ okpomọkụ dị elu.
