Abstract

PROBLEM TO BE SOLVED: To provide a display section of road surfaces which has excellent wear resistance and weatherability, improves the durability of the display of the road surfaces, such as signs and segments by light emissive aggregate and is easily visible in the nighttime. SOLUTION: A subbase course 1 is formed by laying mixed layers formed by incorporating gravel, fillers, etc., into asphalt. Natural or artificial general aggregate 2 and light emissive aggregate 3 are mingled and press fitted into the road surface 10 before curing of the asphalt to form the arrows 11 and the display sections of the segments and induction signs integrally fixed to the asphalt. White or suitably colored porcelain on ceramic particles are used for the general aggregate 2. The light emissive aggregate consisting of inorg. ceramic light emitters into which light emitting materials are incorporated is used for the light emissive aggregate 3. The inorg. ceramic light emitters formed by mixing 5 to 35wt.% light emitting materials with ceramic base materials, firing the mixture and pulverizing the mixture to a granular form are used as the light emissive aggregate 3. The size of the general aggregate 2 and the light emissive aggregate 3 is about 1 to 20mm in diameter.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display section structure for a road surface such as a road or a passage.

[0002]

2. Description of the Related Art Conventionally, in order to prevent a car accident, a colored porcelain particle aggregate is arranged on a pavement road surface to color the marking and division of the road surface and to help prevent slip. At present, it is not possible to effectively recognize the coloring of road markings and sections at night. In view of this, developments have recently been made to improve the visibility of road markings and sections using a luminescent substance.

However, a luminescent substance is hydrolyzed as it is and is generally used as a paint because of poor weather resistance and poor durability, or is used by mixing a luminescent substance into a resin. I have. In all of these cases, they are worn by traffic of automobiles and people, and are not suitable for use on road surfaces from the viewpoint of durability.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is to improve the durability of a luminescent substance with excellent abrasion resistance and weather resistance, thereby making it possible to use a luminescent aggregate to display a sign or a road sign such as a section. The road surface should be excellent in durability, and can easily be viewed at night.

[0005]

According to the present invention, an inorganic ceramic luminous body containing a luminous substance exhibiting luminous properties when irradiated with light is fixed to a road surface as a luminous aggregate. This is a display portion structure on a road surface having a configuration in which a sign or the like indicated by the arrangement of the luminescent aggregate can be visually recognized. Incidentally, the adhesive layer applied to the road surface, luminescent aggregates may be arranged simply, or may be a road surface structure by a neat construction method mixed with natural or artificial aggregates, and may be used as an organic binder such as asphalt , Aggregates, gravel and the like may be mixed to form a roadbed, and a luminous aggregate may be simply arranged on the surface thereof, or a road surface structure by a rolled method in which natural or artificial aggregates are mixedly arranged. Further, the aggregate to be mixed may be appropriately colored.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to illustrated embodiments. The embodiment shown in FIG. 1 displays a traveling direction arrow 11, a dividing line, and a guidance sign 12 on a road surface 10 of a road, and as shown in FIG.
A roadbed 1 is formed by laying a mixed layer in which gravel and filler are mixed, and before the asphalt hardens, a natural or artificial general aggregate 2 and a luminescent aggregate 3 are placed on a road surface 10 where an arrow 11 or the like is to be applied. Mixed press-fitting and fixed integrally with asphalt.

The general aggregate 2 is made of porcelain or ceramic particles colored white or appropriately colored, and has a diameter of about 5 to 20 mm. It prevents slippage.

The luminescent aggregate 3 is made of an inorganic ceramic luminescent material containing a luminescent material. The luminescent material may be a pulverized material of an inorganic phosphor or a phosphorescent phosphor. , Phosphates, silicates, aluminates and the like can be used. Further, as the ceramic base material, a pulverized body of a low melting point ceramic containing silica or alumina is preferable.

Then, a luminescent substance is mixed with the ceramic base material in an amount of 5 to 35% by weight, and the mixture is fired. The substance is wrapped in a ceramic matrix. The size of the luminescent aggregate 3 is about 5 to 20 mm in diameter. The luminescent aggregate of this inorganic ceramic luminous body has been disclosed in a previous application.

According to this embodiment, since the arrow 11 and the like are displayed on the road surface obtained by the rolled method by the general aggregate 2 and the luminescent aggregate 3 of white or appropriate color, the white or appropriate color is used in the daytime. The arrow 11 and the like can be visually recognized, and at night, the arrow 11 and the like can be visually recognized by the light emission characteristics of the luminescent aggregate 3. Further, since the light-emitting aggregate 3 is made of an inorganic ceramic light-emitting body, it has high strength and excellent weather resistance.
In addition to improving the durability of the display section, it also has the effect of preventing slippage.

The amount of the mixture of the general aggregate 2 and the luminescent aggregate 3 is 8 to 8 from the viewpoint of the luminous effect, the stability and the economy.
About 12 kg / m2 is good. Of course 100 at the surface
When only the% luminescent aggregate 3 is used, a strong luminous effect is obtained,
It is effective for the main display. Further, in order to strengthen the adhesion between the general aggregate 2 and the luminescent aggregate 3, a decolorized asphalt or an epoxy resin having high transparency and translucency is provided on the scatter portion thereof.
An acrylic resin or the like may be coated.

Although the embodiment has the above-described configuration, the present invention is not limited to this. For example, as shown in FIG. 3, after the adhesive layer 4 is laid on the road surface, the above-mentioned general aggregate 2 and the luminous aggregate 3 are sprayed before the curing, and the neat construction method of marking the marking portion may be used. In this case, the size of the general aggregate 2 and the luminescent aggregate 3 may be 1 to 5 mm in diameter.

Also, regardless of the material and size of the light-emitting aggregate, any inorganic ceramic light-emitting material containing a light-emitting substance exhibiting light-emitting properties upon being irradiated with light may be used. The content of the luminescent substance is not limited. Further, signs, sections, characters, and the like displayed on the road surface are also appropriate. The means for fixing the luminescent aggregate to the road surface is also optional. Also, regardless of the material and size of the general aggregate, it may be colored in an appropriate color or made the same color as the road surface.

[0014]

According to the first aspect of the present invention, it is possible to clearly recognize the indications such as signs and divisions on the road surface in accordance with the coloring of the general aggregate, and to display the road surface at night by the luminous characteristics of the luminous aggregate. The safety can be ensured by visual recognition, and since the luminescent aggregate is an inorganic ceramic luminous body, the weather resistance and the abrasion resistance are excellent, the durability is improved, and a non-slip road surface is obtained. According to the second aspect, the display can be formed simultaneously with the formation or repair of the roadbed. In the third aspect, the additional display on the road surface can be easily performed.
