Abstract

The invention discloses an anti-ultraviolet-aging anti-rutting agent and a preparation method thereof, wherein the anti-rutting agent comprises the following raw material components by weight: 100 parts of low density polyethylene, 10-30 parts of styrene-butadiene rubber, 10-30 parts of polypropylene, and 5-10 parts of an organic-inorganic composite material, wherein the organic-inorganic composite material is formed by carrying out a co-hydrolysis and condensation polymerization reaction on tetraethyl orthosilicate and organosilane containing a triazinetrione group. According to the present invention, with the anti-rutting agent, the rutting resistance and the low temperature performance of the asphalt concrete can be significantly improved, and the ultraviolet resistance of the asphalt concrete can be substantially improved.

Description

technical field [0001] The invention relates to an anti-rutting agent and a preparation method thereof, in particular to an anti-rutting agent with anti-ultraviolet aging performance and a preparation method thereof. Background technique [0002] With the continuous increase of traffic flow on high-grade highways, as well as the increasingly heavy load of transport vehicles and the channelization of traffic flow, rutting has become the main form of road surface damage, which seriously affects the comfort of road driving and the service life of roads. The research and application of high-performance modified asphalt has become an urgent requirement for pavement construction. [0003] At present, it is an effective means to prevent rutting by increasing the stiffness modulus of asphalt mixture. The techniques used in this technology mainly include the use of high-viscosity hard asphalt binders and the addition of natural asphalt or polyolefin additives to the asphalt mixture....
