DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for marking roads on a drainage pavement by a melt injection method.

[0002]

2. Description of the Related Art In recent years, pavements on highways and general roads have been used.
Drainable pavement has been started to be used as an effective pavement that is expected to improve vehicle running safety in rainy weather and reduce the incidence of accidents. Since this drainage pavement has a structure in which the surface layer has large aggregate particles and many voids and has an uneven road surface, there is a problem in the method of marking the marking lines on the uneven road surface.

[0003]

However, in the case of this drainage pavement, paint can be applied obliquely by the injection nozzles depending on the angle of the vertical injection nozzles, but the film thickness is about 0.3 mm to 0.4 mm. The drying time was longer and the abrasion resistance was inferior to the melting method. As is well known, according to the road marking method by the slit method, the coating film surface is finished irrespective of the unevenness of the road surface, and the gaps of the drainage pavement are filled with the coating material, so that a smooth marking line is obtained. However, during rainy nights, the coating surface of the marking line is covered with a water film, so there is no visual effect, and the coating material penetrates into the drainage pavement and closes the drainage hole, impairing the drainage effect. There were drawbacks. The melting method using an injection nozzle requires a large space for installing an injection pressurizing device, a heat retaining device, and the like, and has not been practically used as a small hand pusher. Injection method, vertical injection is common, and it is an effective method for ordinary pavement, but in drainage pavement, the coating becomes constant when vertical injection is used,
Since the drain holes are closed, rainwater remains on the uneven road surface, and there is a disadvantage that the sign is not visually recognized during rainy night.

However, in view of the relationship between the painting traveling direction and the visual recognition of the vehicle traveling direction depending on the type of traffic division, the lane center line and the lane outer line of the two-way lane, the lane boundary line of the four-way lane, the lane inner and outer lines, In many cases, the direction of painting is limited depending on the type of traffic such as pedestrian crossings, so road markings with good visibility from the driver's eyes while maintaining the drainage effect as described above. Had to be done.
