Description

Lane painting method using room temperature curing lane paint {CONSTRUCTION METHOD FOR ROAD MARKING}

The present invention relates to a lane painting method using a room temperature curing type lane paint, and more particularly, to a lane painting method using a room temperature curing type lane paint to increase durability while improving visibility at night or in rainy weather. .

In general, roads are transport facilities designed to perform the most basic function in transporting goods as well as people's movement, and road marking is applied to the road surface by applying paint to the road surface to induce the direction of progress or to maintain the gap between vehicles. ), etc.

The marking of such lanes is called lane painting, and through this, the driver's convenience as well as safety are promoted.

However, conventionally constructed and used lane painting has difficulty in identifying lanes painted on the surface of the road at night or in rain, and thus has some problems in the lane marking function in special situations.

In addition, conventionally, lanes in highways and traffic congested areas at night in rainy weather have a very important function. Due to the diffuse reflection, the reduction of retroreflection to the lane occurs, and there is a problem in that the visibility is sharply reduced, and the driver has a lot of difficulty in securing the lane.

In this way, at night when it rains, the light emitted from the vehicle's headlights is totally reflected, causing an optical illusion to the driver, which makes it difficult to identify the painted lane, causing a hassle in driving the vehicle, and a factor causing traffic accidents. have.

Incidentally, the incidence of traffic accidents is much higher in rainy weather or nighttime compared to daytime or sunny days, and the amount of predictive information on the road is extremely low due to the reduction in visibility of the lane painting displayed on the road surface. It is a factor that slows down the pre-cognitive reaction of

In addition, conventionally, after painting the lane, there is a problem in that the adhesion is poor, cracks are generated, and the wear resistance is weak, so that the durability is deteriorated due to friction when contacting the vehicle wheel.
