Problems solved by technology

When the traffic volume increases, ruts are more likely to appear on the asphalt pavement. When the rut reaches a certain depth, it will not only affect the stability and comfort of driving, but also accumulate water in the rut after it rains, which will seriously threaten driving safety.

Embodiment Construction

[0012] Get each component raw material by weight proportion in Table 1.

[0013] The weight proportion of table 1 embodiment 1~embodiment 3

[0014]

[0015] The molecular weight of the polyethylene mentioned above is 100,000-300,000.

[0016] The above-mentioned epoxy resin is a bisphenol A type epoxy resin.

[0017] The molecular weight of the above-mentioned polyethylene glycol is 20000-50000.

[0018] The preparation method of the above anti-rutting additive is: polyethylene, polypropylene, diatomaceous earth, polyethylene glycol, boron fiber, epoxy resin, polyester resin, styrene, styrene-butadiene rubber, stearic acid, carbon fiber, Suzhou Mix the soil and mullite evenly, and then put them into the single-screw extruder, set the heating temperature in the four zones to 150-160°C, 170-175°C, 175-180°C, 180-190°C, and adjust the screw speed to 35 rpm / min, extruded, granulated, that is.

[0019] When in use, the anti-rutting additive is added to conventional asphal...

Abstract

The invention provides an anti-rutting additive, which belongs to the technical field of building materials. The anti-rutting additive comprises 10 to 20 parts of polyethylene, 10 to 20 of parts polypropylene, 5 to 8 parts of diatomite, 2 to 4 parts of polyethylene glycol, 2 to 3 parts of boron fibers, 5 to 8 parts of epoxy resin, 3 to 6 parts of polyester resin, 3 to 6 parts of styrene, 7 to 14 parts of butadiene styrene rubber, 3 to 6 parts of stearic acid, 1 to 3 parts of carbon fibers, 2 to 3 parts of Suzhou soil and 2 to 3 parts of mullite. When added into a conventional asphalt material, the anti-rutting additive provided by the invention can significantly improve the strength of an asphalt pavement; an obtained asphalt mixture accords with requirements of relevant specification and has dynamic stability DS of up to 7500 times / mm and failure strain of more than 2500 mu epsilon.

Description

technical field [0001] The invention provides an anti-rutting additive, in particular relates to an anti-rutting additive for asphalt pavement, and belongs to the technical field of building materials. Background technique [0002] With the rapid development of my country's economy, the traffic volume is also growing rapidly, and the volume of freight and passenger traffic is increasing. When the traffic volume increases, ruts are more likely to appear on the asphalt pavement. When the ruts reach a certain depth, it will not only affect the stability and comfort of driving, but also accumulate water in the ruts after rain, which will seriously threaten driving safety. Therefore, strengthening the development of anti-rutting agent products is an urgent problem to be solved in the current asphalt road construction. Contents of the invention [0003] In view of the above comments on the prior art, the technical problem to be solved by the present invention is to develop an a...
