Advantages and features of the present invention, and methods for achieving them will be clarified with reference to embodiments described below in detail together with the accompanying drawings.

In the following, the above-described luminous aggregate and a method of manufacturing the same and a method of paving a luminous road using the same will be described using drawings and examples.

1 is a view showing a method of manufacturing a luminous aggregate of the present invention.

The luminous aggregate of the present invention is prepared by mixing a luminous pigment, distilled water, acrylic resin, and stabilizer and then applying it to the crushed aggregate in an air assisted airless manner.

Specifically, referring to Figure 1, the luminous aggregate manufacturing method, the A-1 step (A10) for crushing the aggregate, the A-2 step (A20) for performing a surface finish after washing the crushed aggregate , Step A-3 (A30) for preheating the aggregate subjected to the surface finishing, Step A-4 (A40) for mixing the luminous pigment, distilled water, acrylic resin, and stabilizer and applying the preheated aggregate to the A-4 A-5th step (A50) for coating the aggregate coated with the pigment, and A-6th step (A60) for performing drying by cooling and impregnating the coated aggregate.

First, in the first step A-1 (A10), the aggregate is crushed. Specifically, the aggregate selected from the stone group alone or in combination is crushed.

The stone group is granite, basalt, silica sand, zircon, germanium, artificial aggregate, etc., and the aggregate is selected from at least one of the stone groups.

The size of the stone to be crushed at the time of crushing is 3 to 8 mm, and it is preferable to crush to a certain size. When the size of the stone is less than 3 mm, durability and application and coating rate of the pigment may be deteriorated, and when it exceeds 8 mm, difficulty in flattening may occur when applying.

The size of the crushed stone can be adjusted according to the application. For example, in the case of sidewalks, bicycle roads, etc., it is crushed to 3 to 5 mm for low load, and for vehicles and motorcycle roads, to 5 to 8 mm for high load. It is preferred.

Next, in step A-2 (A20), the crushed aggregate is washed and then the surface is polished. Specifically, after the crushed aggregate is washed with washing water, the surface is polished.

The washing water used for washing the crushed aggregate may include a surfactant component to facilitate washing of the crushed aggregate.

Since the washed aggregate may have a sharp portion, it is put into a surface trimmer to perform a surface trimming process. The surface trimming prevents injury or damage to a person or bicycle, etc., which may occur due to sharp aggregates on the road.

Next, in step A-3 (A30), the aggregate subjected to the surface trimming is preheated. Specifically, the aggregate subjected to the surface trimming is preheated at 30 to 40°C for 1 to 2 hours.

Through the preheating process, water and surfactant of the aggregate are removed, and the adhesion rate of the pigment is increased.

The preheating process may be variously performed using a preheater, a microwave dryer, etc., and in the summer, natural preheating may be performed at a temperature of 30°C.

Next, in step A-4 (A40), the luminous pigment, distilled water, acrylic resin, and stabilizer are mixed and then applied to the preheated aggregate. Specifically, a luminous pigment, distilled water, an acrylic resin, and a stabilizer are blended and mixed, and then applied to the preheated aggregate in an air assisted airless manner.

The mixture of the luminous pigment, distilled water, acrylic resin, and stabilizer is preferably mixed with 45% by weight of distilled water, 27% by weight of acrylic resin, 15% by weight of luminous pigment, and 13% by weight of stabilizer to improve permeability and visibility.

The air assist airless method is applied using a specially manufactured gun and a pump such as a BBR Vantage 2 Spray Gun, Vantage Gun, MACH 3SL (above Binks product), and the like.

The coating material for application is atomized at a low pressure of 150 to 180 PSI at the airless tip and transferred to the spray gun. At this time, a complete atomization is achieved by supplying a low pressure air pressure in an airless pattern. The perfectly atomized pattern enables high-quality painting.

In the case of luminous pigments, adhesion to aggregate is difficult compared to color pigments, and mixing with distilled water is not smooth, so the application rate can be increased by applying an air assist airless method that replaces coating methods such as vapor deposition and water-immersion coating.

In order to uniformly apply and adhere to the coating, it is preferable to repeat it three times, four times (four times per cycle, and three cycles).

Next, in step A-5 (A50), an aggregate coated with the luminous pigment is coated. Specifically, the aggregate coated with the luminous pigment is coated with a coating solution.

The coating solution includes distilled water, cobalt, methyl silicon, and polysorbate, and is preferably composed of 80% by weight of distilled water, 20% by weight of cobalt, 7% by weight of methyl silicon, and 13% by weight of polysorbate.

The coating process is preferably repeated 4 times for uniform application and adhesion.

By going through the coating process, there are effects such as easy removal of foreign substances on the road, improved permeability, and luminous protection.

Next, in step A-6 (A60), the coated aggregate is impregnated with heating and cooled to perform drying. Specifically, the coated aggregate is heated and impregnated, and the heat-impregnated aggregate is cooled and dried.

The heating is preferably heated at 100° C. for 1 to 2 hours, the cooling may be performed variously using a heater, a heating furnace, a microwave dryer, etc., and the cooling may be performed variously using a blowing fan or the like.

The luminous aggregate is completed through the cooling and drying process.

2 is a view showing the construction method of the luminous aggregate of the present invention.

Referring to Figure 2, the method for manufacturing a luminous aggregate is to mix the luminous aggregate with at least one of S-1 (S10), color aggregate, and base aggregate to clean and dry the ground to be constructed. Step S-2 (S20), Step S-3 (S30) of mixing the combined aggregate, binder, and curing agent, Step S-4 (S40) of applying and mixing the mixed mixture aggregate on the ground, the Step S-5 (S50) for compacting the laid composite aggregate, Step S-6 (S60) for drying the chopped composite aggregate, Step S-7 (S70) for coating the top surface of the dried composite aggregate ), a step S-8 (S80) of drying and curing the coated compound aggregate.

First, in step S-1 (S10), the ground to be constructed is cleaned and dried. Specifically, after removing and evening the foreign matter on the ground to be applied, and then drying naturally if there is moisture.

Next, in step S-2 (S20), an aggregate aggregate is prepared. Specifically, at least one of a color aggregate and a base aggregate is blended with the prepared luminous aggregate to prepare a blend aggregate.

By mixing the color aggregate and the base aggregate with the luminous aggregate to use the combined aggregate, excessive eye fatigue caused when only the luminous aggregate is used can be reduced.

When manufacturing the above-mentioned aggregate, it is preferable to set the mixing ratio of the luminous aggregate to 10 to 20% by volume in consideration of visibility and eye fatigue.

The base aggregate refers to a surface finish after crushing at least one of the stone groups, and the color aggregate may be manufactured by applying the above-mentioned luminous aggregate manufacturing method.

Referring to Figure 3, the method of manufacturing the color aggregate is B-1 step (B10) of crushing the aggregate, B-2 step (B20) of cleaning the crushed aggregate, and then smoothing the surface, smoothing the surface Step B-3 (B30) for preheating the aggregate, distilled water, acrylic resin, pigment, stabilizer, and then applied to the preheated aggregate (Step B-4) (B40), the aggregate coated with the pigment Step B-5 (B50) of coating, and step B-6 (B60) of heating and impregnating the coated aggregate to perform drying.

Steps B-1 to B-3 are the same as steps A-1 to A-3.

In step B-4, a dye, distilled water, an acrylic resin, and a stabilizer are mixed and then applied to the preheated aggregate in an air assisted airless manner.

The mixing of the dye, distilled water, acrylic resin, and stabilizer is preferably 50% by weight of distilled water, 25% by weight of acrylic resin, 15% by weight of pigment, and 10% by weight of stabilizer.

In addition, in the case of the above-mentioned color aggregate, it is possible to apply vapor deposition and water-immersion coating, which are general application methods.

In addition, as the pigment, an edible pigment may be used when manufacturing an eco-friendly aggregate.

Steps B-5 to B-6 are the same as steps A-5 to A-6.

In addition, the color aggregate can be used by mixing a variety of color aggregates during construction.

Next, in step S-3 (S30), the compound aggregate, the binder, and the curing agent are mixed. Specifically, the blended aggregates, binders, and curing agents are weighed and then mixed using a mixer.

The mixing ratio of the combined aggregate, the binder and the curing agent is preferably 6.5 parts by weight of the binder and 1.5 parts by weight of the curing agent relative to 1 part by weight of the combined aggregate.

The binder is a polyurethane binder, and the polyurethane binder may be composed of 60% by weight emulsifier, 10% by weight emulsion polymer, 25% by weight urethane, and 5% by weight alcohol.

Since the formulation aggregate is mixed with a polyurethane binder and a curing agent and is installed on the road, it can have excellent durability and excellent water permeability because it can form voids.

The mixing is preferably performed for 5 to 7 minutes based on 20 kg of the aggregate aggregate for uniform mixing.

Next, in step S-4 (S40), the mixed compound aggregate is applied to the ground and laid. Specifically, the mixed aggregate in which the binder and the curing agent are mixed is applied to the cleaned ground to be the target for construction.

Next, in step S-5 (S50), the laid aggregate is compacted to planarize it. Specifically, in order to flatten the compound aggregate laid on the ground, it is compacted using a heating rolling machine or the like.

Next, in step S-6 (S60), the chopped compound aggregate is dried. Specifically, it is dried for 1 to 2 days to cure the chopped compound aggregate.

Next, in step S-7 (S70), the top surface of the dried compound aggregate is coated. Specifically, coating is performed using a coating solution to protect the top surface of the dry compound aggregate.

The coating process of step S-7 (S70) may be omitted.

Next, in step S-8 (S80), the coated aggregate is dried and cured. Specifically, the coated aggregate is dried and cured to complete the road pavement construction using the luminous aggregate.

In the following, using the embodiment of the luminous rod prepared through pavement construction using the luminous aggregate of the present invention, the blending ratio of the blended aggregate is presented.

<First Example>

The first embodiment is a sample using a luminous aggregate (100% luminous aggregate, particle size of 1 mm) of the present invention.

<Second Example>

The second embodiment is a sample using a mixed aggregate (luminous aggregate 50%, colored aggregate (purple) 50%, particle size 2mm) in which the luminous aggregate and the colored aggregate of the present invention are mixed.

<Example 3>

The third embodiment is a sample using a blend aggregate (luminous aggregate 20%, color aggregate (blue, brown) 80%, particle size 3mm) in which the luminous aggregate and color aggregate of the present invention are mixed.

<Example 4>

The fourth embodiment is a sample using a mixed aggregate (luminous aggregate 10%, colored aggregate 90%, particle size 3mm) in which the luminous aggregate and the colored aggregate of the present invention are mixed.

As shown in FIG. 4, it can be seen that in the first embodiment using only luminous aggregates, it is preferable to use a combination aggregate because it may give excessive fatigue to the eyes.

In addition, when comparing the second to fourth examples, the higher the particle size of the aggregate, the better the visibility, and considering the fatigue and visibility of the eyes, it can be seen that the fourth embodiment is most preferable.
