Abstract

The invention discloses an iron-adhesive highway asphalt which is prepared from the following components in parts by weight: 20-40 parts of 90# matrix asphalt, 3-10 parts of styrene-butadiene-styrene triblock copolymer, 3-10 parts of aromatic oil, 2-5 parts of aviation kerosene, 5-10 parts of machine oil, 10-20 parts of rubber, 2-5 parts of terpene resin, 1-5 parts of organic acid, 2-5 parts of adhesive elastomer material, 5-15 parts of kaolin, 3-7 parts of APAO, 2-5 parts of polyethylene and 0.5-2 parts of phosphoric acid. The iron-adhesive highway asphalt has the advantages of low temperature resistance, no embrittling at low temperature, high adhesive force for steel surfaces, and excellent water resistance, and is suitable for cold areas.

Description

[0001] Technical field [0002] The invention relates to a sticky iron road asphalt and a preparation method thereof. Background technique [0003] Iron-bonded road asphalt material, also known as steel-bonded road asphalt material, is similar to the waterproof adhesive layer of conventional steel surface road paving and the lower steel surface contact layer. The iron-bonded highway asphalt material should meet the following two requirements: one is firm adhesion to the steel surface, and the other is waterproof, acting as a waterproof adhesive layer, and the surface of ordinary expressways has a certain degree of water permeability. Put an end to the contact of water and steel, and prevent the rust and corrosion of steel on the surface of the bridge (Scheme design and experimental study of waterproof bonding layer for steel bridge deck pavement; Zhang Lanjun, Mou Jianbo). [0004] At present, in the production of iron-bonded highway asphalt materials, domestic products are pro...
