Problems solved by technology

At present, for the maintenance project of steel bridge deck pavement, the high-temperature mixing epoxy asphalt pavement technology was adopted early in China, and the high-temperature mixing epoxy asphalt concrete has very strict requirements on the construction temperature and time, which is limited to relatively low temperature. High spring and summer construction, and the concrete curing time is as long as about 10 days. At the same time, large mixing equipment and special cementing material adding equipment need to be erected near the construction site, which still cannot solve the problem of steel bridge deck pavement maintenance.

Abstract

The invention discloses a steel bridge deck pavement cold mixing maintenance material and a manufacturing method thereof. The maintenance material comprises a resin detritus waterproof layer, a resin bonding layer and a resin concrete pavement layer. The resin detritus waterproof layer is coated on a steel bridge panel required maintenance and is formed by solidifying resin and detritus spread on the surface of the resin. The resin bonding layer is coated on the resin detritus waterproof layer. The resin concrete pavement layer is coated on the resin bonding layer and is formed by solidifying the resin and aggregate in a mixed mode. According to the maintenance material, construction is convenient, influence on construction conditions by temperature is small, performance is excellent, maintenance time is short, production is convenient and rapid, construction period is short and influence on traffic is small.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a steel bridge deck pavement cold-mix curing material and a preparation method thereof. Background technique [0002] At present, the mainstream steel bridge deck pavement technology in China is mainly epoxy asphalt concrete and cast asphalt concrete pavement technology. The pavement of steel bridge decks has always been a worldwide problem, and its service life is shorter than that of ordinary pavements, especially under domestic use conditions, and some serious diseases begin to appear in the second year of use. For example, the Jiangyin Bridge was paved with poured asphalt concrete, and defects such as rutting and cracks began to appear in the second year; the Runyang Bridge was paved with epoxy asphalt technology, opened to traffic in 2005, and entered the stage of frequent maintenance in 2007. [0003] However, after the pouring asphalt concrete and epoxy aspha...
