Icing-resisting road and construction method thereof

Abstract

The invention provides an icing-resisting road and a construction method thereof. The icing-resisting road comprises a graded rubble layer, a cement stable base layer, a stable rubble layer and a bituminous concrete layer which are sequentially distributed from bottom to top. The bituminous concrete layer comprises a bituminous concrete lower layer, an oil pipe layer and a bituminous concrete upper layer which are sequentially distributed from bottom to top. The oil pipe layer comprises oil pipes which are uniformly laid and communicate, and the oil pipes are connected with a solar heat-absorption plate; the bituminous concrete lower layer and the bituminous concrete upper layer are both obtained through laying of a mixture; the mixture is formed by mixing rubbles, bitumen, a phase transformation unit and steel fibers; the interior of the phase transformation unit is spherical phase transformation paraffin wax, and the exterior of the phase transformation unit is a wrapping layer which is formed by mixing graphene, nanometer aluminum oxide, heat conduction fibers, cement and water; and the phase transformation temperature of the phase transformation paraffin wax is 0-5 DEG C. The icing-resisting road is easy to construct and good in icing-resisting effect.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to an anti-icing road and a construction method thereof. Background technique [0002] In winter and early spring when the temperature is lower than 0°C, the snow may freeze on the road immediately or melt and form road icing on the road due to the drop in temperature. As long as the temperature does not rise enough to thaw the ice, it will remain rock-solid and an important culprit of traffic accidents. The existing road is distributed with graded crushed stone layer, cement stabilized base layer, stabilized crushed stone layer and asphalt concrete layer successively from bottom to top. [0003] At present, road deicing mainly adopts mechanical and chemical methods. The mechanical method is to directly act on the road ice accumulation and compacted snow through mechanical devices. It mainly includes impact ice breaking, multi-section whip whipping deicing, ro...

AI Technical Summary

Problems solved by technology

The mechanical method is to directly act on the road ice accumulation and compacted snow through mechanical devices. It mainly includes impact ice breaking, multi-section whip whipping deicing, roller rotating ice removal and shovel removal, etc., but ice accumulation and compacted snow are combined with the road surface. Tight, if the strength of the deicing machine is too small, the two cannot be separated and cannot be removed cleanly; if the strength is too large, it will damage the road markings, or even destroy the road surface, and the technical level is low, the reliability is poor, there are many failures, and the service life is short

[0004] The chemical method uses chemical agents to reduce the melting point of ice and snow, but it is greatly affected by the ambient temperature. If the temperature is too low, the effect will be significantly reduced, and the chemical agents will cause serious erosion of asphalt and cement concrete, and the damage speed will be much faster than ordinary freeze-thaw cycles. The damage caused by it also causes corrosion pollution to soil, crops and surface water, etc.
