Further, a resin binder, a colored porcelain aggregate,
By applying the top coat, a color pavement having excellent durability in addition to slip resistance can be obtained.

[0006]

In the resin-based non-slip pavement according to the conventional neat method, since the hard aggregate 3 is not completely mixed in the resin binder 2, the hard aggregate is not used during or after construction. Part 3 is dropped and peeled off, which is wasted, and it takes time to clean it.

Further, the resin binder 2 is composed of a main material based on a flexible modified epoxy resin and a curing agent such as a polyamine resin. Since the resin binder 2 is a two-component mixed resin, the strength gradually increases through cross-linking. It takes time such as the curing period.

The second object of this invention is to provide a road surface treatment agent that is simple, has a short construction period, can be colorized and is abundant, can easily adjust the groundwork, and can correct rutting. Thirdly, in addition to the purpose of the road surface treatment agent and the road surface treatment structure, a beautiful surface treatment with a seamless finish is provided. It is an object of the present invention to provide a road surface treatment device which can be easily and reliably constructed.

[0009]

In order to achieve the above object, the present invention provides a road surface treating agent comprising a thermoplastic resin 100

Next, a road surface treatment apparatus of the present invention for applying such a road surface treatment agent to a road surface will be described.

FIGS. 2 to 10 show a first embodiment of the road surface treating apparatus according to the present invention, in which a rectangular main body frame 5 which can be driven by wheels 4 has a short side 5a of the main body frame 5.
And a traveling frame 6 which is a parallel frame having an interval to move along the longitudinal side 5b. 7 in the figure
Is a traveling motor for the traveling frame 6 provided on the body frame 5 side, and drives the traveling frame 6 to move laterally by using a sprocket and a chain as a transmission mechanism.

Further, a projector 10 is provided so as to move along the length direction of the traveling frame 6. As shown in FIGS. 6 to 10, this projector 10 is a type capable of storing about 100 kg of the road surface treating agent, has a stirring blade 14 inside, and a shutter 15 having a film thickness adjusting plate 15a at the lower end. A hopper 11 that is disposed and is kept warm by a propane burner; a feed roller 12 that is provided with flanges 12a on left and right sides and transfers a road surface treatment agent from the hopper 11;
A rotating body 13 having blades 13a for striking the material sent in proximity to the ground 12 against the ground.

The periphery of the rotating body 13 is bent by a cover 16 so that the material is not scattered, and a burner 17 for heating is provided at an important part of the projector 10. In the figure, reference numeral 18 denotes a motor for driving the feed roller 12, and 19 denotes a motor for driving the rotating body 13.
The feed roller 12 has a width of about 25 cm and a diameter of about 15 cm, is connected to the motor 18 via a speed reducer, and makes one rotation per 30 seconds.
The rotating body 13 has a diameter of 10 cm and a plurality of blades 13a. The rotating body 13 is directly connected to the motor 19 and rotates at a high speed of about 1,500 / min. The rotating body 13 is close to the feed roller 12 so that the blade 13a enters between the flanges 12a (a clearance of 0.1 to 0.3 mm).
Let it.

As shown in FIG. 5, the projector 10 is supported by a tilting mechanism which is suspended from the traveling frame 6 by an electric cylinder 20 so as to be tiltable, and is supported by the tilting mechanism. The bearing of the projector 10 having a threaded connection is screwed to a screw shaft 21 along the traveling frame 6. The screw shaft 21 was connected to a motor 22 mounted on the traveling frame 6 by a sprocket, a chain, or the like as a component of a moving mechanism of the projector 10.

The main frame 5 and the traveling frame 6 and the projector 10 and the traveling frame 6 have engagement between the traveling wheels 8 and the rails 9 so as to ensure smooth movement.

Next, usage and operation will be described.
Although not shown, the road surface treatment apparatus is towed by a kneader truck. From the kneader of the kneader truck, the baking bauxite having a particle size of 1 to 5 mm is weighed to 400 to 900 parts by weight with respect to 100 parts by weight of the thermoplastic resin. The road surface treating agent mainly composed of the mixed material of the parts is transferred to the hopper 11.

When the shutter 15 is opened, the road surface treating agent flows on the feed roller 12, and approaches the blade 13 a of the rotating body 13 as the feed roller 12 rotates. The thickness of the road surface treating agent on the feed roller 12 is determined uniformly by the film thickness adjusting plate 15a of the shutter 15, and the flange 12a prevents the road surface treating agent from flowing left and right. When the feed roller 12 makes a quarter turn, the motor 22 is started by the setting of the preset mechanism of the counter, the screw shaft 21 is rotated, and the lateral traveling of the projector 10 along the traveling frame 6 starts.

At this time, the road surface treating agent is
13a hits the road. When the vehicle continues to travel sideways (50-55 cm / sec) and the paint reaches 12.5 cm before the end point, the shutter 15 closes and the supply of the road surface treating agent to the feed roller 12 is stopped. The shutter 15
The road surface treatment agent below the surface treatment agent is still sent to the feed roller 12, and after a quarter of a turn, the road surface treatment agent is cut off and projection stops.

The projector 10 is slightly moved in the longitudinal direction of the main frame 5 by the movement of the traveling frame 6 along the longitudinal side 5b of the main frame 5 by the operation of the limit. At this stage, as described above, the shutter 15 opens, and the feeding roller 12
At the time of ４ rotation, the lateral running in the direction opposite to the above direction is started.

In this way, the projector 10 repeats the horizontal reciprocating movement and the vertical movement to freely move in the body frame 5 in both the X and Y directions with respect to the body frame 5. As a result, it is possible to construct a clean and seamless finish.

Also, when the projector 10 moves laterally along the traveling frame 6 and approaches the longitudinal side 5b of the main body frame 5 at the end point, the electric cylinder 20 is operated to tilt the projector 10 by about 30 °. . In this way, the projector 10 is brought close to the main body frame 5 in an oblique state,
The road surface treating agent can be projected to a portion slightly outside the long side 5a of the road.

In this way, the road surface is made of a thermoplastic resin.
For 100 parts by weight, calcined bauxite with a particle size of 1 to 5 mm
A road surface treating agent containing 400 to 900 parts by weight of a mixed material as a main component is applied in a thickness of 3 to 10 mm.

The test results for the effect of the present invention are shown below. In the following table, (1) to (3) are examples of the present invention, and (4) and (5) are comparative examples.

[Example] [Comparative Example] (1) (2) (3) (4) (5) Thermoplastic resin 100 100 100 100 100 100 Calcined bauxite 400 650 900 300 1000 1000 Additives 15 23 30 12 33 Total 515 773 1030 412 1033 Finished appearance * 1 Good Good Good Good Good Good Good Good Rough slide resistance dry * 2 288 88 95 86 107 (BPN) wet * 3 65 85 88 52 98 98 Appearance after 3 months * 4 Good good Good Good Good Good Good appearance of dirty aggregate Yes * 1 The composition was heated and melted at 200 ° C and applied to an asphalt block with an applicator having a gap of 5 mm. * 2 The sliding resistance (BPN) of the coating film formed in * 1 was measured by Portable Skid Resistance Tester. * 3 Measured in the same manner as * 2, with the sample surface wet with tap water. * 4 The test piece prepared in * 1 was subjected to a backlash test on the constituent roads for three months, and compared with an untested plate.

According to this table, when the calcined bauxite is not in the range of 400 to 900 parts by weight with respect to 100 parts by weight of the thermoplastic resin, if the amount is small, the slip resistance of the wet is reduced, and if the amount is large, the aggregate is removed. Can be found.

Further, at a specific place such as a curve, a separation zone or a hill which is particularly slippery, as shown by a chain line in FIG. 1, a groove 23 having a width of about 1 to 3 cm extending in the width direction or the length direction of the road is formed on this application surface. It may be formed at an interval of 1 to 3 cm as appropriate. This groove
Forming of 23 is performed by applying a road surface treating agent and then press forming.

In this way, the presence of the groove 23 at the specific place gives resistance and vibration to the tire of the vehicle, making it more difficult to slip and allowing ventilation.

FIG. 11 shows a second embodiment of the road surface treating apparatus according to the present invention. In FIG. 11, reference numeral 24 denotes a truck such as a carrier such as a truck, and the truck 24 has 100 parts by weight of the thermoplastic resin as described above. In contrast, calcined bauxite with a particle size of 1 to 5 mm
A kneader 25 for storing a road surface treating agent composed mainly of 900 parts by weight of a mixed material, a pressurized sub-tank 26 for receiving the road surface treating agent from the kneader 25, and a compressor 27 were provided.

A discharge nozzle 29 is provided at the end of a flexible pipe 28 extending from the pressurized sub-tank 26. An air hose 30 from the compressor 27 connects the air hose 30 to the pressurized sub-tank 26, branches off in the middle, and cuts the end. Is combined with the discharge nozzle 29 to form a discharge nozzle for air injection.

In the road surface treatment apparatus of the second embodiment,
The road surface treating agent transferred from the kneader 25 to the pressurized sub-tank 26 flows through the flexible pipe 28 by air pressure and is ejected from a discharge nozzle 29 at the tip. Strong and efficient injection can be obtained by the attraction of air injection from the tip. Therefore, the road surface treating agent is sprayed and painted on the road surface while sequentially moving the discharge nozzles 29 by hand.

FIGS. 12 to 16 show a third embodiment of the road surface treating apparatus according to the present invention. The material tank 34 has a hand-operated trolley 31 and a slit 32 formed by a shutter 32 on its lower surface.
Was provided. In the figure, 35 is an operation handle of the shutter 32, and 36 is a fuel cylinder for a burner.

As shown in FIG. 14 and FIG.
Consists of a combination of a fixed frame 32a and a movable piece 32b, which is formed by engaging a convex ridge 37 having an acute angle with a concave groove 38 having a triangular cross section in which it is fitted. In this way, when the shutter 32 is closed, the ridge 37 and the concave groove 38 are firmly engaged with each other, so that the road surface treating agent in the material tank 34 does not leak.

Further, if an elastic member 39 such as a rubber packing is provided on the side of the concave groove 38, this serves as a packing seal, so that leakage can be further reduced.

Outside the shutter 32, sled-shaped closing plates 40a, 40 for partially closing the slit opening 33 in the longitudinal direction.
b was removably mounted with bolts. These closing plates 40a and 40b have different widths, and the slit openings 33 can be made different by attaching them.

In this manner, calcined bauxite having a particle size of 1 to 5 mm was added to 400 to 900 parts by weight per 100 parts by weight of the thermoplastic resin.
A road surface treating agent mainly composed of a mixed material consisting of parts by weight is stored in a material tank 34 and is applied while adjusting the discharge amount by the width of the slit opening 33 formed by the shutter 32 while manually pushing the carriage 31.
