ADVANTAGES OF USING MODIFIED BITUMEN IN INCREASING THE TEMPERATURE RESISTANCE OF ASPHALT CONCRETE PAVEMENT

Abstract

The service life and quality indicators of asphalt concrete pavements largely depend on their resistance to temperature effects. Intense summer heat and severe winter frosts often lead to plastic deformations, cracks, and other defects in the road surface. The use of modified types of bitumen is recognized as an effective solution to this problem. Bitumen modified with polymers, rubber, or other additives increases the thermal resistance of asphalt concrete mixtures, ensuring their mechanical stability and durability. This study examines the technological properties of modern modified bitumen used in the production of heat-resistant asphalt concrete, as well as their mechanism of action and practical effectiveness.
