DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an existing pavement or a new pavement for suppressing snow compaction or icing that adheres to a pavement surface of a pavement for vehicle traffic at a low temperature in winter in a snowy cold area or a mountainous area. The present invention relates to a method for constructing a pavement road having a function of suppressing freezing on a surface layer of a road. That is, it can be called a vehicle-passing rubber rail paved road having a function of suppressing a frozen road surface due to a difference between vehicle passing pressure, vehicle-passing friction heat, and frictional force of a road surface material.

[0002]

2. Description of the Related Art The state of a conventionally provided pavement having a freeze suppression function is roughly as follows. A. The first method-on paved roads with freeze suppression function,
There is a road surface laying material in which a chlorine-based antifreezing material is mixed with a pavement material mainly composed of bituminous material, and is generally called freeze-delayed pavement. This is because 4 pieces of anti-freezing material are added to the surface asphalt mixture.
８8% mixed and rolled to a finished thickness of 3-5 cm for construction.
Similarly, to keep the antifreeze effect of chloride for a long time,
A road surface deicing material in which a deicing agent is covered with a rubber film has also been considered. B. Second method: There is a road surface laying material for surface layer which uses rubber particles in a proportion of 3 to 4% based on the mixture to the same pavement and uses the elasticity of the rubber particles. This is called elastic pavement. Similarly, there is a construction method in which a rubber chip having a large particle size is pressed and rolled immediately after the heated mixture having a relatively large amount of fine particles is laid. C. The third method-generally widely spread, effective and simple is direct spraying of anti-freezing material and anti-slip material,
Spray each time to maintain the effect. Even when anti-freezing measures are not required, non-slip pavement is implemented in places where there is a risk of slippage, such as slopes and curved sections. The general non-slip pavement is a mixed pavement using a surface bituminous mixture containing a large amount of coarse aggregate. In the scattering type non-slip method, a hard aggregate is bonded to a road surface with a resin-based adhesive. D. From the fourth method, there is a rolled asphalt pavement in which a single-grained crushed stone pre-coated with asphalt is rolled and fixed immediately after the asphalt mortar mixture is spread and leveled. E. FIG. Diffusion pavement or grooving method is a method having the function of increasing the slip resistance from the fifth method to the slipping effect due to the drainage of the pavement surface and the roughness of the road surface. The grooving method cuts grooves at regular intervals on the pavement surface with a special machine, but in the repair and repair of rutting on asphalt pavement, breakers are cut off using a breaker or asphalt cutter. As a method of cutting asphalt and concrete pavement, a method using a cutting edge of a motor grader for repairing irregularities on the surface of asphalt pavement, and a concrete cutter are often used. In addition to the groove, there are a machine for scraping by heating with a burner and a machine for shaving with a rotary gear. Sharpen the existing pavement,
Alternatively, a method of installing a lane marking and a road marking to be displayed using paints can be considered as a method of newly installing a scraping structure.

[0003]

Problems with the conventionally provided pavement having the function of suppressing freezing can be pointed out as follows. A. Problems with the first method Even if the construction cost is high, it is difficult to maintain the effect of preventing freezing of chlorides over a long period of time, and even if it is maintained, the amount of chloride to be retained is limited. There is not much difference. Until now, this function was exhibited by the scraping effect of spiked tires, but this has been limited, making it difficult to use. B. Problems with the second method It is economical, but not a simple method, since the purpose is to mix it with the paving material and lay it all over. The effect is thin unless a large amount of rubber chips are used, and if the amount is large, problems arise in durability and workability. The most effective antifreeze method is to use facilities such as road heating, but the pavement costs such as construction costs and maintenance costs are high. C. Problems with the third method Anti-freezing material and anti-slip material must be sprayed as necessary, and maintenance is complicated, and the spray amount is large. D. Problems with the fourth method Although effective on slopes and the like, the coarse aggregate is easily peeled off by a snow removing machine or the like, and has a problem in durability. E. FIG. Problems with the fifth method The grooving method has a slip prevention effect when a groove is formed perpendicularly to the vehicle traffic direction, but when the groove is parallel, the groove is easily slipped. F. In addition, as the icy road surface has become a social problem due to the spike control law, urgent measures to prevent road surface freezing are required, and the current methods cannot meet the needs of society in terms of mass. Was. For this reason, there has been a need for an economical, simple, and suitable road suitable for the area, with a reduced icy road surface and a safe vehicle-passing paved road.

[0004] The present invention has been made in view of such problems of the prior art, and has as its object to provide the following. That is, in order to suppress the frozen road surface,
It is necessary to expose the road surface by snow removal of the road surface by a snow removing machine and pavement having a frozen road surface suppressing function. It is not economically an easy method to control the entire pavement in order to suppress the frozen road surface as in the conventional method. Therefore, the present invention covers only necessary portions. That is, attention was paid to the traffic direction of the vehicle, particularly the contact portion between the vehicle tires and the pavement road surface. The approach from the pavement to control icy roads is, today, considered hot or elastic, chloride infiltration, water infiltration or drainage. That is, road heating, elastic pavement, freeze delay pavement, drainage pavement, grooving pavement and the like.

According to the present invention, a pair of rail-shaped grooves for two wheels are formed on a pavement surface layer surface in a vehicle traffic direction, and rubber and polyethylene to which snow and ice are less likely to adhere to the grooves are used. Came up with. (See Fig. 1) Vehicle types include small cars, ordinary cars, and large cars. Each vehicle tire front tread has a large grip of 120c.
m, 140cm, 180cm, Tire contact width is 12 ~
It was assumed to be 20 cm. The adhesion of snow and ice on the road surface where the vehicle tires touch the ground is prevented by the vehicle passing pressure and traffic friction force,
It was thought that a function to suppress freezing would occur. That is, it was considered that snow and ice were removed by the difference in the frictional force of the road surface material and the vehicle traffic, and the surroundings were melted by the frictional heat of the vehicle traffic, and slip was prevented by the road surface having the frictional force around. Bitumen oil slicks are exposed on the pavement surface on newly-built pavement surfaces, and may be easily slipped by rain. For this reason, it may be necessary to take more effective slip prevention measures in the vicinity thereof to further prevent slip. In the case of the surface treatment method for slip prevention in such a case, the spray-type surface treatment method in which the slip prevention material is directly applied to the existing pavement surface via a resin that has the effect of preventing slip has the effect of enhancing the slip prevention effect. It is a simple method as a pavement structure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In tests related to slip control on road surfaces of road pavement and prevention of slip on winter road surfaces, the role of fillers was highly evaluated in experiments on road engineering asphalt pavement in experiments on compounding test methods for surface asphalt mixture. Experimental research using filler bitumen as a binder is also involved in this invention. That is, the amount of filler bitumen has an effect on flow resistance, the amount of coarse aggregate having a diameter of 2.5 to 13 mm has an effect on slip and strength, and the amount of fine aggregate having an intermediate diameter has an effect on durability and workability. Ratio, ie, F / A = 1.75, ratio of crushed stone to sand, ie, G / S
= Fine grain gap ascon pavement of about 40/60 is widely used in cold snowy regions such as Hokkaido. B. On slopes and other roads, rubber mat laying methods and roll door asphalt compounding methods have been implemented in winter to prevent vehicle slippage. C. In the surface treatment of pavement, the construction method is mixed type,
There are roughly four categories: spray-on, slurry-seal, and fog-seal. Here, in the case of road surface slip, the mixed type may be considered according to the term of bituminous pavement, but in the case of spray type, aggregate with a large anti-slip effect is scattered and adhesive However, there is a problem that a joining material having a large value must be selected. For this reason, a method of attaching a silica sand or emery of 0.5 to 2.0 mm with a resin such as an epoxy resin has been considered. D. In the Abashiri Development and Construction Department of the Hokkaido Development Bureau, the purpose is to suppress the frozen road surface by attaching ceramics used together with pottery etc. in a zebra-like shape, alternately with the road surface, perpendicular to the vehicle running direction near intersections, etc. Test paved with. This has been conventionally considered in terms of thermal conductivity in consideration of road heating.

E. The test for the present invention was started by first performing a simple test on a privately owned road surface using substitute materials. There was a need to find and test materials that served the same role needed for the idea of the present invention. Therefore, first, pressure-resistant rubber hose φ32, φ
25, φ18mm, stainless steel dry pole φ3-4c
m, L3.5-4m, JIS PVC pipe for drainage
K6741, VU100, 75, 50, JISK674
2, VP30, 25, 20, 16, 13, drain gutter W10
cm, synthetic rubber, urethane resin, etc. F. In order to increase the strength of the rubber hose, it was necessary to take measures such as double-plying a PVC pipe into a mandrel to increase the strength, and use these. These were installed on asphalt, cement mixture, and gravel using privately owned roads as described above. In examining the degree of slippage and the impact of compacted snow on these private lands, the following results were found from these test results. In other words, the method of shaving the pavement road surface or pouring a rubber solution into the pavement road surface is effective because the work can be performed smoothly without forming a rut on the road surface. Even when the thickness is small, the same effect was obtained when a sheet of a product made of a resin composite layer was stuck to the pavement surface. It should be noted that when conducting the above-described tests, hoses and pipes are treated, and when the deicing agent is sealed in the voids, it is clear that chlorides and the like have a solution on the pavement and have an infiltration effect, It is clear that passing hot water through hoses and pipes also has the effect of suppressing freezing.

G. Rather than using a pair of rails, one on one side and one on the other side, two on one side, two on the other side, or three on one side and three on the other side, to remove the adhesion of snow compaction Although effective, the risk of slip is great. With a single width, widening the width is dangerous unless it is an elastic pavement material. It has been found that it is preferable to set one of the three wires at a width of about 5 cm at intervals of 20 cm, and to take a slip prevention measure at the interval. H. It is almost infinite to use an antifreeze pavement on the entire road surface of a vehicle on a pavement road in winter. For this reason,
In the present invention, a method widely used is adopted in consideration of the depth of the groove and the material to be used, and also in consideration of durability such as easy peeling. I. It is important to take measures for the minimum necessary parts and select the necessary places, but sufficient measures are required for slopes, curves, shade of structures, and entrances to tunnels and bridges. J. The present invention is very effective in dry areas with little snowfall, and in Japan, it is very effective in areas near the Sea of Okhotsk.
The period from January to the end of March is available. K. In addition, the present invention is most effective in preventing black ice burn that occurs when the snow is cooled down to 0 ° C. or less, even when snow is frequently removed and snow is removed. If the traffic volume is low without frequent snow removal, extreme effects cannot be obtained. For this reason, it is necessary to consider regional characteristics in order to use it economically and effectively.

[0030]

Since the present invention is configured as described above, the following effects can be obtained. 1. According to the present invention, when the vehicle has a road surface arranged in two or three rows in accordance with the tread width of a large vehicle such as a truck or a bus such as a truck or a bus according to the present invention, the destruction of a black ice barn which occurs at a low temperature in winter due to rubber elasticity or the like. The effect of the present invention is great. For reference, the dimension of L in FIG.
At 0 cm, L1 is 120 cm. 2. Many traffic accidents occur in winter, most of which are caused by slipping into the oncoming lane. For this reason,
With the rough elastic pavement material, the protrusion can be prevented by the vibration effect of the vehicle. 3. The ability of a small car to drive along the exposed surface of the pavement surface on the inside of a rail-shaped street destroyed by a large car helps to recognize safe driving in terms of safety and psychology. 4. A feature of the present invention is that a rail in which snow and ice do not stick to the road surface is set, and heat such as electricity is effective.However, in terms of economy, elastic pavement material or rubber material is used as in the present invention. Use is more efficient and most suitable. 5. In addition, when using a plastic material with very poor thermal conductivity, which is difficult for snow and ice to adhere to, it has the same effect as a rubber material that has elasticity at low temperatures.In this case, considering the contact width with the tire, The pavement that increases the slip resistance can be provided by a more effective slip prevention measure. 6. Unlike in the case of making a groove perpendicular to the direction of travel of the vehicle in the direction of travel, the surface condition on the rails is good, so that the vehicle can run stably, and in addition to increasing the driving force and noise It also produces significant effects such as prevention.
