Problems solved by technology

[0006] Due to the aging phenomenon of asphalt materials, the performance of most modified asphalt and mixtures will decay over time, which will still reduce the high temperature stability of asphalt pavement
This kind of problem can only be solved by repairing the existing road surface, which not only causes economic waste but also has a great impact on ensuring smooth traffic
In addition, some asphalt pavements after adding modifiers cannot achieve pavement regeneration is also a problem that plagues road workers

Abstract

The invention relates to a heat-reflection coating of an asphalt pavement. The coating comprises the following components in parts by weight: 41-126 parts of mixed resin system, 11-54 parts of heat-reflection filler, 6-29 parts of light-weight calcium carbonate, 6-14 parts of talcum powder, 0.5-12 parts of dispersant and 1.5-13.5 parts of initiator. The heat-reflection coating has a stronger capacity of resisting vehicle load effect and high wear resistance, and is excellent in construction performance, good in adhesive force on pavement, and good in cooling effect.

Description

technical field [0001] The invention belongs to the technical field of road materials, and in particular relates to a heat-reflecting coating for asphalt pavement. Background technique [0002] Asphalt pavement is a pavement structure composed of asphalt material as a binder to bond mineral materials to build a surface layer and various bases and cushions. Because of its black color, it is also called black pavement. It is precisely because the road surface is black in color and the solar absorption rate is as high as 0.85-0.95, so it has a high solar heat absorption capacity. In summer, under the continuous heat radiation of the sun, the asphalt pavement absorbs a large amount of heat and accumulates it in the pavement structure, making the pavement temperature much higher than the air temperature. [0003] The early damage phenomena of expressway asphalt pavement are mainly manifested as: water damage, looseness, rutting, cracks, oil flooding, etc. The generation of ruts...
