Abstract

The invention discloses a modified asphalt waterproof roll for a railway roadbed. The roll comprises a main rotating shaft, wherein a modified asphalt waterproof roll is mounted on the outer side of the main rotating shaft; antiskid bulges are arranged on the outer surface of the modified asphalt waterproof roll, each antiskid bulge comprises an outer wear-resistant gelatinous layer, a corrosion-resistant layer, a flame retardant layer, a first inner waterproof layer, a first isolation layer, a fracture-resistant layer, a tire base layer, a second inner waterproof layer and a polyurethane rubber layer, the corrosion-resistant layer is mounted on the bottom surface of the outer wear-resistant gelatinous layer, the flame retardant layer is mounted on the lower end surface of the corrosion-resistant layer, the first inner waterproof layer is mounted on the bottom surface of the flame retardant layer, the first isolation layer is mounted on the bottom surface of the first inner waterprooflayer, the fracture-resistant layer is mounted on the lower end surface of the first isolation layer, and the tire base layer is mounted on the bottom surface of the anti-fracture layer. The roll hashigh strength, high temperature resistance, cold resistance, corrosion resistance and high tensile strength.

Description

technical field [0001] The invention relates to the technical field of asphalt waterproof coiled material, in particular to a modified asphalt waterproof coiled material for railway subgrades. Background technique [0002] Asphalt waterproofing membrane refers to a roll material made of asphalt material, tire material and anti-sticking material spread on the surface, also known as linoleum. Commonly used in post-type waterproof layer. Bitumen waterproofing membrane refers to tire membrane and tireless membrane. Any roll-shaped material made of thick paper or glass cloth, asbestos cloth, cotton and linen fabrics and other tire materials impregnated with petroleum asphalt is called tire-shaped roll material; asbestos, rubber powder, etc. are mixed into the asphalt material, and after rolling The resulting roll material is called a rolled roll, that is, a tireless roll. [0003] However, the existing asphalt waterproof membrane has low tensile strength, is not resistant to h...
