Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing:

[0038] A kind of asphalt modifier of the present invention is characterized in that its component comprises tire rubber powder, polyethylene, silicon dioxide and rubber oil, the plasticized rubber viscous shape that obtains by stirring, heating, extruding, cooling section The particles are asphalt modifiers.

[0039] The plasticized rubber viscous particles are cylindrical, the diameter A of the cylinder is 3mm-15mm, and the height H of the cylinder is 3mm-15mm.

[0040] The plasticized rubber viscous particles are long strips, the width B of the strips is 3mm-15mm, and the height L of the strips is 3mm-15mm.

[0041] The tire rubber powder is 85-95 parts by weight, the polyethylene is 3-6 parts by weight, the silicon dioxide is 1-3 parts by weight, and the rubber oil is 1-7 parts by weight. The tire rubber powder, polyethylene, composite stabilizer, Silica and rubber oil...

Abstract

The invention aims to provide an asphalt modifier and a preparation method thereof, which overcome the disadvantages of nonuniform modification, serious pollution and hidden danger caused by adding rubber powder into asphalt and solve the technical problem of the modification and prefabrication of the rubber powder. The invention provides the asphalt modifier. The asphalt modifier is characterized by comprising the following components of: tire rubber powder, polyethylene, silicon dioxide and rubber oil, wherein the components are stirred, heated, extruded, cooled and cut to obtain plasticized rubber sticky particles, namely the asphalt modifier. The plasticized rubber sticky particle product of the invention greatly reduce high-temperature processing and pollution of rubber asphalt; the produced rubber asphalt sticky particles are a directly thrown type novel internal modification material and can be directly thrown into the asphalt and stones for mixing; and the asphalt modifier is odorless, can reduce secondary pollution, and has better meltability than that of rubber powder modified asphalt. The rubber asphalt particles are black sticky particles and are easy to package and transport.

Description

technical field [0001] The invention relates to an asphalt modifier, in particular to a granular plasticized rubber asphalt modifier for road surface processing and a preparation method thereof. Background technique [0002] At present, asphalt modifier is a natural or synthetic organic or inorganic material added to asphalt or asphalt mixture, which can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt. For example, in order to improve the mechanical properties (strength and toughness, etc.) of asphalt, materials such as polymers, resins, plastics, carbon black, and inorganic salts are added to increase the strength and toughness. [0003] The usual asphalt modifier is waste rubber powder, and a large amount of rubber powder needs to be transported to the asphalt laying site. At the construction site, the rubber powder is put into the heated asphalt for modification. Due to uneven mixing and heating, the rubber powder tends to settle t...
