Abstract

The invention relates to a stable asphalt pavement material. The stable asphalt pavement material is prepared by, by weight, 0.2-0.5 part of diphenylamine, 0.23-0.4 part of crosslinking agent, 20-36 parts of base asphalt, 0.4-0.7 part of Arabic gum, 6-10 parts of sodium lauryl alcohol polyoxyethylene ether sulfate, 0.8-2.4 parts of dimethyl phthalate, 1-1.7 parts of phenol, 0.4-1.2 parts of triethoxy silane, 0.5-1.4 parts of dispersing agent, 6-9 parts of adhering auxiliaries, 2-4 parts of potassium chloride, 5-8 parts of aluminum stearate, 6-9 parts of water-based acrylic emulsion, 4-7 parts of preservatives and 6-10 parts of polyisobutene. The stable asphalt pavement material has temperature stability and is resistant to low-temperature cracking and traveling vehicle damage, good in deformation resistance and extremely good in stability.

Description

technical field [0001] The invention relates to a stable asphalt pavement material. Background technique [0002] At present, more and more asphalt pavements are used on expressways in our country, while cement pavements are less and less, showing a one-sided trend. Because the asphalt pavement must have good durability against natural factors while having a certain bearing capacity. With the rapid development of highway traffic, more and more attention has been paid to asphalt pavement, and the requirements for materials are getting higher and higher, requiring it to show sufficient stability in high temperature environments, crack resistance in low temperature conditions, and good durability. Water stability, long-lasting anti-aging and anti-skid properties that are conducive to safety, etc., to ensure good service functions of asphalt pavement. However, the asphalt materials currently used still have many deficiencies, such as cracks in various forms, water seepage and ...
