Abstract

The invention discloses a self-melting colored permeable integral pavement. The pavement comprises a low-freezing-point protective agent coating, a low-freezing-point colored surface layer, a low-freezing-point primary-color bottom layer, a coarse sand leveling layer, a graded broken stone layer and a plain soil layer which are sequentially arranged from top to bottom. According to the pavement, an environment-friendly low-freezing-point material is mixed with concrete and a protective agent material to form the low-freezing-point protective agent coating, the low-freezing-point colored surface layer and the low-freezing-point primary-color bottom layer, the pavement freezes due to the winter snowfall, snow water rapidly infiltrates downwards after being melted, snow on the surface of thepavement melts continuously, the snow melting process is accelerated, and potential safety hazards caused by snowfall freezing are eliminated; and the pavement has great economic and social significance in solving the traffic safety problem of ice-snow-covered pavements in China and the urban waterlogging problem, decreasing the traffic accident rate, reducing traffic accident losses and protecting the ecological environment at the periphery of the pavement.

Description

technical field [0001] The invention relates to a pavement structure, in particular to a self-melting snow-melting colored water-permeable integral pavement, which belongs to the technical field of road engineering. Background technique [0002] Ordinary permeable roads cannot guarantee the safety of road driving under the conditions of snowfall and freezing in the north. It is necessary to use mechanical deicing agents and mechanical snow plows to remove ice and snow on the road surface. This method is easy to cause damage to the road surface. The deicing agents currently used on asphalt pavement have a certain corrosion effect on the pavement, and have certain damage to the surrounding ecological environment, and the cost is relatively high. [0003] At present, ordinary permeable pavement has insufficient load-bearing capacity and cannot meet the needs of freezing and thawing resistance in the north. There is no report on the application of self-melting snow-related perm...
