Abstract
This paper studies the viscosity-toughness enhancement technology of the layered structure of composite asphalt pavement,aiming to solve the problem that composite asphalt pavement is prone to diseases under the action of traffic loads and environmental factors.By integrating high-content dissolved rubber asphalt,high-viscosity and high-elasticity modified asphalt,interface roughening treatment technology and multi-type synergistic strengthening technology of layered systems,the durability and service performance of the pavement have been significantly enhanced,as well as its resistance to rutting,cracking and water damage.The results show that this technology can double the fatigue life of the asphalt surface layer,extend its service life by 3 to 5 years,while reducing construction and maintenance costs,as well as reducing energy consumption and carbon emissions.关键词
