Problems solved by technology

[0005] Judging from the current technical state, most cooling materials are mainly reflective or radiant materials, and are coated on the road surface with a single-layer coating scheme. They are easily worn out under the repeated action of the wheels, and the durability is not good. Affect the road surface structure texture, insufficient anti-skid performance; or directly mixed into asphalt mixture, but it is only suitable for new asphalt pavement, and the applicability to existing pavement is not strong

Abstract

The invention discloses a multilayer composite thermal insulation covering and a preparation method thereof, belongs to the field of civil engineering materials, and aims to provide a functional composite paving technology with the advantages of being obvious in thermal insulating and cooling effects and capable of improving the sliding resistance and abrasion resistance of the pavement. Accordingto key points of the technical scheme, the multilayer composite thermal insulation covering contains a porous bead insulating resin bonding layer, a porous aggregate insulating resin non-slip layer and a thermal radiation resin face seal layer arranged in sequence from bottom to top. On the basis of ensuring pavement performances of the pavement, such as sliding resistance, abrasion resistance and the like, the internal temperature of the pavement and paving can be reduced to 10-15 DEG C, the 'cool' pavement is realized, the rut resistance and slip resistance of the pavement in an extreme high temperature season are improved, the service life of the road is prolonged, and the overall service quality of the road is improved. The multilayer composite thermal insulation covering disclosed bythe invention can be applied to the field of road and bridge engineering such as steel bridge deck pavement, asphalt pavement and cement concrete pavement.

Description

technical field [0001] The invention relates to the field of civil engineering materials, in particular to a multilayer composite heat insulation cover and a preparation method thereof. Background technique [0002] Nowadays, the construction of traffic infrastructure quality projects is in full swing, and people's requirements for road service quality are getting higher and higher. However, domestic extreme high temperature and heavy-duty operating conditions restrict the service status of roads: on the one hand, in extreme high temperature seasons, the temperature of road and bridge pavement is extremely high, the surface temperature of steel bridge deck pavement reaches above 70 °C, and the temperature of asphalt and cement concrete road surface reaches 60 °C Above, walking on the road surface is like "sauna", seriously affecting the comfort of pedestrians and driving; on the other hand, domestic roads are prone to problems such as rutting and shifting under the coupling ...
