Embodiment 1
[0026] An anti-migration asphalt mixture, comprising the following components in parts by weight:
[0027] 2000 parts of aggregate, 100 parts of base asphalt, 7 parts of rubber powder, 3 parts of SBS modifier, 5 parts of tackifier, 0.5 parts of polyesterfiber, 0.2 parts of UV slow-drying glue, 3 parts of sponge, 2 parts of carbon black powder share.
[0028] Aggregates include sand, ore powder, ceramic powder, steel slag, and glass particles mixed together.
[0029] Preferably, the tackifying component is prepared by mixing rosin resin, chlorinated paraffin, acrylate, vulcanized silicone rubber, and methyl silicone oil in a ratio of 30:7:5:12:3 by weight. All kinds of aggregates, such as sand and gravel, mineral powder, ceramic powder, steel slag, glass, etc., have excellent adhesion effect, avoid the phenomenon of asphalt migration, and improve the problem of easy peeling of aggregates.
[0035] An anti-migration asphalt mixture, comprising the following components in parts by weight:
[0036] 1000 parts of aggregate, 100 parts of base asphalt, 5 parts of rubber powder, 1 part of SBS modifier, 4 parts of tackifier, 0.5 part of polyacrylonitrilefiber, 0.2 part of UV slow-drying glue, 3 parts of sponge, manganese dioxide 2 servings.
[0037] Aggregates include sand, ore powder, ceramic powder, steel slag, and glass particles mixed together.
[0038] Preferably, the tackifying component is prepared by mixing rosin resin, chlorinated paraffin, acrylate, vulcanized silicone rubber, and methyl silicone oil in a ratio of 30:7:5:12:3 by weight. All kinds of aggregates, such as sand and gravel, mineral powder, ceramic powder, steel slag, glass, etc., have excellent adhesion effect, avoid the phenomenon of asphalt migration, and improve the problem of easy peeling of aggregates.
[0039] Preferably, the UV slow-drying adhesive is composed of polyester acrylate, 1,6-he...

Abstract
The invention provides a migration-resistant asphalt mixture, which comprises the following components in parts by weight: 1000-2000 parts of aggregate, 100 parts of matrix asphalt, 5-7 parts of rubber powder, 1-3 parts of SBS modifier, 4-5 parts of sticky component, 0.5-1 part of soft polymerfiber, 0.2-0.5 part of UV slow-drying glue, 2-5 parts of elastic multi-cellular additive, and 1-2 parts of light-shielding additive; Materials include sandstone, mineral powder, ceramicpowder, steel slag, and glass cullets; the glass cullets are made of ordinary waste glass after physical or chemical toughening, and then crushed into particles with a particle size of less than 1mm by a crusher. Made after small particles. The asphalt mixture of the invention can avoid the phenomenon of migration of asphalt, thereby improving the problem that aggregates are easy to peel off.
Description
technical field [0001] The invention relates to the technical field of asphalt, in particular to an anti-migration asphalt mixture. Background technique [0002] Asphalt is a black-brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Pitch can be divided into coaltarpitch, petroleumpitch and natural pitch. Among them, coaltar pitch is a by-product of coking, petroleum pitch is the residue after crude oildistillation, and natural pitch is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as pavement. [0003] After the asphalt and aggregate are laid, a layer of asphalt pavement is formed on the concrete floor. During the laying of asphalt and aggregate, due to the high...
