不同种类沥青对灌入式半柔性材料的影响.

In order to clarify the influence of asphalt species on the pavement performance of semi-flexible pavement, used matrix asphalt, SBS modified bitumen and high-viscosity modified asphalt to prepare semi-flexible pavement materials, perform gradation optimization, and test to explore the influence of asphalt species on semi-flexible pavement perfusion rate, high temperature stability, water stability and strength in the past. The results showed that the stability of the parent asphalt mixture prepared with different asphalt increased first and then decreased with the increase of oil-stone ratio, while the porosity decreased continuously, and the stability of the mixture using SBS modified bitumen and high-viscosity modified asphalt increased under the same oil-stone ratio and decreased. The type of asphalt had little effect on the perfusion rate, SBS modified bitumen and high-viscosity asphalt could improve the water stability and high temperature stability and strength of the pavement in the past, and the lifting effect was basically the same.
