Road-surface microwave deicing method based on high-dielectric-constant material covering

Abstract

The invention discloses a road-surface microwave deicing method based on high-dielectric-constant material covering. The problems that in the prior art, heating is uneven, and deicing efficiency is low are mainly solved. The road-surface microwave deicing method includes the steps that an ice layer with the thickness over than 5 mm is mechanically cut to prepare into a thin ice layer with the thickness smaller than 5 mm; the thin ice layer is covered with a high-dielectric-constant material with the dielectric constant larger than 3.7, and the lower surface of a high-dielectric-constant material layer (4) is closely attached to the upper surface of the thin ice layer; then a T-shaped metal conductor belt (1) and a metal conductor plane (2) are electroplated on the upper surface of the high-dielectric-constant material layer, coplanar waveguide is composed of the high-dielectric-constant material layer (4), the T-shaped metal conductor belt (1) and the metal conductor plane (2), and feeding is carried out through a coaxial line (3) for the coplanar waveguide. Resonance surface waves generated on the lower surface of the high-dielectric-constant material layer penetrates through thethin ice layer to directly act on the road surface, the effects of evenly heating the road surface and rapidly deicing are achieved, and the method can be used for road surface deicing.

Description

Technical field [0001] The invention belongs to the technical field of road surface treatment, and particularly relates to a road surface microwave deicing method, which can be used for road deicing. Background technique [0002] Pavement icing poses a great safety hazard to traffic. Research has found that the friction coefficient of snowy roads is only 46.7% of that of dry asphalt pavements, and icy roads are only 30% of that of dry asphalt pavements. A small friction coefficient is very easy Causes a traffic accident, so the snow and ice should be cleared in time on a snowy day. For compacted snow and ice, it is extremely difficult to remove and requires special removal equipment. [0003] At present, the commonly used methods of removing ice on the road mainly include passively inhibiting road surface snow icing and active snow melting. Among them, the passive method includes spreading snow melting agent method, manual removal method, spreading sand and gravel material method...
