Problems solved by technology

As a high-heat energy storage material, phase change materials can release a large amount of heat to delay the temperature drop when the ambient temperature drops. It can theoretically solve this problem, but there is little progress in the research on its application pathways and application methods.
At present, the snow melting and ice melting technology promoted in various places is only aimed at newly built roads, but there is no relevant supporting technology for the roads in service at the "throat" of road traffic

Embodiment 1

[0064] According to the T0703 asphalt mixture specimen preparation method (wheel rolling method) in the highway engineering asphalt and asphalt mixture test regulations (JTG E20-2011), the dense asphalt concrete AC- 13 gradation standard, using basalt aggregates to make asphalt concrete slabs. Further apply a self-regulating asphalt concrete thin layer overlay (such as figure 1 shown), the specific steps are: configure the self-regulating asphalt concrete thin-layer overlay material according to the formula in Table 2, and coat the self-temperature-regulating asphalt concrete thin-layer overlay material on the surface of the asphalt concrete slab with a thickness of about 10mm, and Sprinkle gravel evenly on the concrete overlay material, remove unbonded gravel after curing, and prepare the control group and experimental groups 1-3. The control group and the experimental group were tested for performance. Specifically, the control group and the experimental group were immersed...

Embodiment 2

[0070] According to the T0703 asphalt mixture specimen preparation method (wheel rolling method) in the highway engineering asphalt and asphalt mixture test regulations (JTG E20-2011), the dense asphalt concrete AC- 13 gradation standard, using basalt aggregates to make asphalt concrete slabs. Further apply a self-regulating asphalt concrete thin layer overlay (such as figure 1 shown), the specific steps are: configure the self-regulating asphalt concrete thin-layer overlay material according to the formula in Table 4, and coat the self-regulating asphalt concrete thin-layer overlay material on the surface of the asphalt concrete slab with a thickness of about 10mm, and Sprinkle gravel evenly on the concrete overlay material, remove unbonded gravel after curing, and prepare experimental groups 4-9. Performance tests were performed on the prepared experimental groups, and the performance of each experimental group was similar to that of the implementation groups 1-3.

Abstract

The invention relates to the field of road engineering, in particular to a concrete overlay material and a preparation method and an application thereof. The concrete overlay material is prepared from the following components in parts by weight: crushed stone, epoxy resin, a curing agent, polyethylene glycol and carbon. The concrete overlay material has the advantages that the high-heat energy storage characteristic of a phase change material is utilized, the concrete overlay material can be used as a temperature-adjusting asphalt concrete thin overlay, the functions of inhibiting ice and melting snow are realized, and the influence to the road pavement structure and road pavement safety by ice and snow hazards can be effectively overcome.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a concrete overlay material and its preparation method and application. The concrete overlay material may be an asphalt concrete overlay material. Background technique [0002] Pavement ice and snow damage is a major factor that affects pavement safety and pavement structure life in the long term. If the impact can be reduced in a short period of time, great social and economic benefits can be generated. As a high-heat energy storage material, phase-change materials can release a large amount of heat to delay the temperature drop when the ambient temperature drops. It can theoretically solve this problem, but there is little progress in the research on its application pathways and application methods. At present, the snow melting and ice melting technology promoted in various places is only aimed at newly built roads, but there is no relevant supporting technology for the active r...
