Abstract

The invention discloses a novel high-strength anti-rutting modified asphalt which comprises a 70#Esso heavy duty bitumen, a modifier and an additive; the additive comprises an anti-rutting agent, a stabilizer and a cosolvent; the mass percent of the components is as follows: 80-95% of 70#Esso heavy duty bitumen, 1-10% of modifier, 1-10% of anti-rutting agent, 0.1-5% of stabilizer and 1-10% of cosolvent. The invention also discloses a preparation method for the novel high-strength anti-rutting modified asphalt. The modified asphalt prepared according to the invention has an excellent high-strength anti-rutting property and high splitting tensile strength, is capable of effectively prolonging service life of road materials and increasing driving comfort level of vehicles and has high economic benefit.

Description

technical field [0001] The invention relates to the technical field of road engineering materials, in particular to a novel high-strength anti-rutting modified asphalt and a preparation method thereof. Background technique [0002] At present, the commonly used SBS modified asphalt mixture pavement on the road has a particularly serious rutting problem under high temperature and heavy load. The main manifestation is that rutting causes excessive deformation of the road surface, which affects the smoothness of the road surface; the thickness of the asphalt layer at the wheel marks on the road surface is thinned, which weakens the overall strength of the surface layer and the pavement structure, which is easy to induce other diseases. [0003] The occurrence of rutting seriously affects the service life of the pavement and even aggravates the occurrence of other road diseases, such as looseness, potholes, network cracks and other diseases, thereby reducing the quality of aspha...
