It has the good high temperature stability, the crack resistance in low temperature; Good anti-wheel rut ability, reduces high temperature plastic deformation; Improves the asphalt water stability; Enhances the pavement anti-skid capability; Enhances pavement bearing capacity; Strengthened the asphalt durability, anti-weary, anti-aging; Enhances the asphalt and the mineral aggregate coherence, preventes the moisture content causes asphalt flaking in its contact surface place invasion and so on. Therefore, it obtains the widespread application in domestic as well as the overseas first-class highway, has become the irreversible tendency. This article key introduces mainly asphalt type and choice, modified bituminous mixture ratio design, construction craft and quality control technology.
