Description

Asphalt road waterproof coating composition {Waterproof Coating Composition for Asphalt Road}

The present invention relates to an asphalt road waterproofing coating composition, and more particularly, to an asphalt road waterproofing coating composition having excellent mechanical properties as well as excellent waterproofing performance and excellent anti-slip performance.

The most commonly used road paving material is bitumen asphalt concrete, which is widely applied to road pavement due to its short construction period and economic feasibility. However, it has the disadvantage of being unstable and short-lived. When Vitmin is exposed to the outside, it undergoes chemical change and oxidation by UV rays and moisture, and loses elasticity and adhesion over time. Eventually, due to this deterioration of the physical properties, vitmin loses the adhesive strength of the aggregate, which causes cracks and the like. When moisture oxidation and radiant heat pass through the cracks in the asphalt, the asphalt corrosion process proceeds rapidly. In addition, thread cracks occur due to the cause of deterioration, the asphalt adhesive component flows down due to the summer temperature rise, the asphalt adhesive component disappears due to the automobile tire, and only the aggregate remains, and the cracking phenomenon is accelerated.

In addition, due to heavy snowfall in winter and the use of a large amount of calcium chloride, snow changes into moisture and penetrates into the asphalt, and the infiltrated moisture is frozen and expanded again due to the temperature drop, thereby accelerating asphalt cracks. In the case of a city, a pot hole is immediately induced, and thus a traffic accident is caused by the occurrence of irregularities on the road surface. The economic cost of the short maintenance cycle of asphalt roads is enormous. Also, the asphalt is heated to 190~230℃ after cutting and repaved to high temperature, and carbon dioxide emissions are very large due to the use of heavy equipment along the pavement, and the waste asphalt from cutting is environmentally friendly has a great influence on

In order to reinforce these shortcomings of asphalt, it is necessary to construct an asphalt protective coating that is strong against moisture and temperature.

Republic of Korea Patent Publication No. 10-2222229 (2021.03.04.) discloses an organic-inorganic hybrid asphalt concrete coating agent for asphalt repair and reinforcement and asphalt coated therewith.

The organic-inorganic hybrid asphalt concrete coating agent for asphalt repair and reinforcement has the advantage of improved mechanical properties, but has a disadvantage in that the waterproof performance is insufficient.
