Abstract

The invention belongs to the technical field of road maintenance and particularly relates to a roadbed surface dehumidifier. The roadbed surface dehumidifier comprises a substrate, a moisture absorption layer, a moisture fixing agent and a solar heat absorbing coating, wherein a first surface of the substrate is contacted with the surface of a roadbed; an evaporant is arranged on a second surfaceof the substrate; the moisture absorbing layer and the moisture fixing layer are sequentially arranged in the substrate from the first surface of the substrate to the second surface of the substrate;the moisture absorbing layer comprises a moisture absorbent comprising an inorganic drying agent and a polymer drying agent; the moisture fixing layer comprises a moisture fixing agent comprising capillary biological fiber; an evaporation layer comprises the evaporant comprising the solar heat absorbing coating. By the aid of the roadbed surface dehumidifier, the technical problems that road damage and maintenance cost are increased and the service life of roads is greatly shortened due to lack of effective roadbed surface dehumidifiers in the prior art are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, and in particular relates to a roadbed surface dehumidifier. Background technique [0002] As one of the main carriers of my country's transportation methods, roads are of great significance to my country's economic and social development. Due to the direct contact with the external environment, the road will be affected by different types of environmental factors during the application process. [0003] Among many environmental factors, water, as the most common environmental factor, has an extremely important impact on road performance and durability. During the rainy season in summer, continuous rainfall will cause water accumulation and over-humidity on the road surface. The gradual increase and the repeated rolling of the vehicle load lead to serious diseases such as spalling, pumping, and pits on the road surface, which directly affects the performance of the road, greatly reduce...
