INVESTIGATION OF RHEOLOGICAL PROPERTIES OF MODIFIED BITUMEN
At the present time the most widely used type of road pavement is asphalt-concrete pavement produced on the basis of oil bitumen. One of the efficient ways to increase the quality and durability of asphalt-concrete pavement is modification of bitumen. Though Russian specialists still don’t have the global view of the ideal and real asphalt cement, the requirements to its quality and durability indicators in the composition of road structure haven’t yet formed. The authors present the investigation results of the properties of oil asphalt cement containing 0.5-2.0% of modifier “Olazol”. The physical, mechanical and rheological properties of the modified bitumen are determined. The dependences of the dynamic viscosity of the modified bitumen from the quantity of introduced modifier, shear rate and reheat temperature are analyzed.
