Description

The Method and Devices of the Road Marking for the Pavement

In the conventional asphalt pavement, wheel rutting is easily generated, which continues to accumulate and cause road pavement as a permanent deformation. This pavement is a major cause of traffic accidents caused by the hydro plane of the vehicle during the rainfall or by the freezing of the winter season. In order to reduce this phenomenon, it is recently constructed by SMA pavement method to increase the interengagement between aggregates using coarse aggregates, and is now designed and constructed with cement concrete pavement in view of maintenance costs. It is a trend. However, in the case of the SMA pavement using the coarse aggregate, the space between the aggregates increases, and the conventional painting method does not uniformly paint the empty spaces between the aggregates and prevents the slippage in the case of the cement concrete pavement. There is a joint for it, so that the paint and glass grains are not evenly distributed in the groove of the joint. Moreover, when the sun rays shine horizontally in the morning or evening and when the roads are placed in the east and west directions, the evaporation of the lanes occurs severely, so the lanes disappear completely depending on the area, causing traffic accidents. This often happens.

In order to prevent such a problem, the present invention sprays at the same time in the same direction as the lane progression direction, and to allow large-diameter glass grains to be seated and fixed in a natural drop type, which is suitable for painting new construction roads. Methods should also be developed and show that the development of all industries should be equally advanced. In order to reduce the waste caused by frequent paint replacement instead of a small paint canister in lane painting construction, it is an object of the present invention to induce a large amount of paint storage tank into an environmentally friendly construction method.

The development of the technology for the pavement is mostly related to the material and construction method of asphalt, as shown in Republic of Korea Patent Publication 1999-011444 and is not well done with respect to the lane painting method.

Conventional technologies for lane markings are mostly related to a non-slip facility, and Korean Patent Publication No. 1997-05021515, Korean Patent Publication No. 1998-09049737, Korean Patent Publication No. 1996-12041111, and the like.

In recent years, SMA pavement and cement concrete pavement, which are mainly used, have excellent function of extending durability, while the space between aggregates is widened by the use of coarse aggregates, and the paint and large diameter glass balls are uniform because of the slip groove. There is a disadvantage that can not be applied to the two-way spray method was used. 1 and 4 show the surface layer of the SMA pavement and the cement concrete pavement using coarse aggregate, and shows the appearance of the paint applied when spraying in only one direction in the vehicle moving direction. If this lane is the center line, it causes the lane to disappear in the driver's field of view. In particular, a one-lane one-way national road without a center line divider causes a very serious situation, and a lot of lane evaporation occurs at a time when the sunlight is obliquely in the morning or evening.

FIG. 2 and FIG. 5 show the appearance that the paint is uniformly applied to the coarse aggregate and the joint groove of the surface layer by spraying in both directions in the driving direction of the lane-painted vehicle. [Fig. 3] and [Fig. 6] are sprayed with paint in both directions, and then sprinkled with a thick drop of glass uniformly in a natural fall-off manner to exhibit a retroreflective effect. In this case, if the bumpy convexity effect is increased, the paint coating film and glass particles are not buried in the rain so that the lane can be seen well even at night. To do this, there is a method of spraying crushed stone while changing the order of lane application.

To explain this method in more detail,

Iii) Apply paint in the opposite direction of vehicle travel.

Ii) Spray litter and glass pellets.

I) Apply paint in the direction of vehicle travel.

Ⅳ) Spray glass balls.

And in step ii) it may be sprayed by mixing the crushed stone and glass beads.

These lane painting methods include air drying traffic paints (KS M 5322), air drying water-borne traffic paints (KS M 5340), and heating road markings. It is applied to paints (hot spray type traffic paints, KS M 5336) and consists of coloring pigments, extender pigments, synthetic resins and other additives. These are liquid or thermoplastic powder coatings used by mixing or separately applying glass beads when retroreflective is necessary.In the present invention, paint storage tanks of 1 to 5 metric tons or more are used to reduce the air contact of the paint as much as possible and to improve construction convenience. It was planned.

Recently developed SMA pavement and cement concrete pavement are highly durable, but there is a lot of space on the surface of the surface layer and because of the groove of the anti-slip joint, paint is not uniformly applied during lane drawing, so the evaporation phenomenon of the lane depends on the terrain and time zone. It prevents the disadvantages that occur and provides the driver with excellent visibility at night and especially during the rainy day at night, which greatly assists in safe driving and increases the volume of the paint storage tank, thereby reducing the amount of waste of small containers generated during construction. Environmentally friendly construction method was induced.
