Problems solved by technology

[0002] The surface of the anti-seepage layer of the asphalt concrete anti-seepage panel of the dam of the water conservancy and hydropower project must be coated with a layer of asphalt mastic for protection. The commonly used asphalt mastic has low anti-aging performance and will age in long-term exposure to sunlight; currently The anti-seepage of the building surface and the asphalt mastic on the bridge deck also have low anti-aging performance, and aging occurs after several years of use

Abstract

The invention relates to a material for impermeable layer protection of rolled type asphalt concrete face slabs of hydraulic and hydroelectric engineering, building surface impermeable coatings and bridge pavement, in particular to an anti-ageing asphalt mastic material and a preparation method thereof. The mastic material is prepared from components in parts by weight as follows: 100 parts of asphalt, 125-145 parts of cement and 130-150 parts of sand. The material has high ageing resistance and low flow value, and the problem that painted asphalt mastic is aged after a few years is solved.

Description

technical field [0001] The invention relates to a water conservancy and hydropower project rolling type asphalt concrete panel anti-seepage protection, building surface anti-seepage coating and bridge deck pavement materials, in particular to an anti-aging asphalt mastic material and its preparation method . Background technique [0002] The surface of the anti-seepage layer of the asphalt concrete anti-seepage panel of the dam of the water conservancy and hydropower project must be coated with a layer of asphalt mastic for protection. The commonly used asphalt mastic has low anti-aging performance and will age in the long-term exposure to sunlight; currently The anti-seepage of the building surface and the asphalt mastic for bridge deck pavement also have low anti-aging performance, and aging occurs after several years of use. [0003] Asphalt mastic is a kind of asphalt mixture composed of asphalt, fiber stabilizer, sand powder and a small amount of fine aggregate. It ha...
