Description

Road surface maintenance material capable of dehumidifying and quickly drying and road surface dehumidifying method

Technical Field

The invention belongs to the technical field of road materials, in particular to a road surface maintenance material capable of dehumidifying and quickly drying and a road surface dehumidifying method,

background

Because the development process of the expressway in China is short, the pavement structure is relatively single from form to material composition, and certain contrast is formed between the pavement structure and the expressway in China with wide geographical area and complicated climatic conditions. Meanwhile, because of large road traffic volume and more heavy-duty vehicles in China, the damage of the road surface of the expressway within the service life is exposed in the road operation period. Among road diseases, water damage is one of the most common forms of early damage in current highway asphalt pavements. The water damage is an early damage phenomenon of a pavement after a pavement structure layer penetrates water, and mainly shows a process that water causes an asphalt film to fall off from the surface of aggregate and lose adhesive force. The phenomena are mainly loosening, particle dropping and pit and groove. The water enters the interior of the pavement structure layer through various ways, and scours the interior of the asphalt layer and the semi-rigid base layer to form cynanchum pulp, net cracks, pot holes and the like.

The damage is mainly characterized in that the asphalt mixture is stripped under the action of water, the structural layer strength of the asphalt pavement is reduced, the water stability of the semi-rigid base layer is deteriorated after the semi-rigid base layer is corroded by water, and the bearing capacity of the semi-rigid base layer is reduced. The large-area early damage of the expressway caused by water damage can be caused on the asphalt pavement from south to north in China. Particularly, in the spring season, plum rain season and rainy season of the expressway in a rainy and humid area, the pavement can be pitted, loose, dropped and even grooved. The water damage of the highway has wide influence range, the damage to the road surface is serious, the direct and indirect economic losses are huge, and the adverse social influence is caused. Therefore, it is highly desirable to provide reasonable materials for dehumidifying roads to reduce the occurrence of water damage in asphalt pavements.

The results of the test for the dehumidifying quick-drying performance of examples 1 to 28 and comparative examples 1 to 5 are shown in the following tables 4 to 6.

TABLE 4 test results of the dehumidifying and quick-drying performance of the road surface maintenance material for dehumidifying and quick-drying of examples 1 to 10 of the present invention

Table 5 test results of dehumidification and quick-drying performance of examples 11 to 22 of road dehumidification and quick-drying pavement maintenance materials

Table 6 test results of dehumidification and quick-drying performance of road dehumidification and quick-drying pavement maintenance materials in examples 23-28 and comparative examples 1-5

Remarking: and paving the road dehumidifying and quick-drying pavement maintenance material on the surface of a porous ceramic plate with the thickness of 2cm according to the maximum moisture absorption amount, the moisture absorption speed and the evaporation time, and then carrying out a dehumidifying and quick-drying performance test.

According to the results of the tests on the dehumidification quick-drying performance of the table 4 to 6, the maximum moisture absorption amount of the road dehumidification quick-drying pavement maintenance material shows a significant increase trend along with the gradual increase of the addition amount of the moisture absorption material and the moisture guide material, the increase amplitude is highest under the optimal addition amount, when the addition amount is higher than the optimal addition amount, the growth speed is gradually reduced, and when the moisture absorption material is not added in the road dehumidification quick-drying pavement maintenance material (comparative example 2), the maximum moisture absorption amount is reduced by about 75.6%.

The unit moisture absorption time is mainly related to the moisture absorption material and the moisture conduction material, along with the increase of the mixing amount of the moisture absorption material and the moisture conduction material, the unit moisture absorption time of the road dehumidification quick-drying pavement maintenance material is obviously shortened, when the moisture conduction material is not mixed in the road dehumidification quick-drying pavement maintenance material (comparative example 1), the unit moisture absorption time is prolonged by 50.6 percent, and when the moisture absorption material is not mixed in the road dehumidification quick-drying pavement maintenance material or the moisture absorption material and the moisture conduction material are not mixed in the road dehumidification quick-drying pavement maintenance material, each square meter of the road dehumidification quick-drying pavement maintenance material cannot absorb 500g of external water, so that the unit moisture absorption time cannot be estimated.

The water evaporation time of the road dehumidifying and quick-drying pavement maintenance material is related to the ultraviolet absorbent, and is obviously shortened along with the increase of the doping amount of the ultraviolet absorbent and the blue light transmittance, and when the road dehumidifying and quick-drying pavement maintenance material does not contain the ultraviolet absorbent, compared with the embodiment containing the ultraviolet absorbent in the same proportion, the unit water evaporation time is prolonged by 351.6 percent, and the time for the material to completely evaporate the absorbed water is greatly increased.

When pore-forming materials are lacked in the road dehumidification quick-drying road surface maintenance material, the maximum moisture absorption amount is reduced, and the unit moisture absorption time is obviously prolonged, so that the four-channel polyester fibers are embedded in the maintenance material due to the lacked pore-forming materials, the moisture guide material is filled and covered by the cementing materials and the fillers, the action space of the four-channel fibers is occupied, the moisture guide efficiency of the four-channel polyester fibers is greatly reduced, and the unit moisture absorption time is obviously prolonged.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
