Abstract
Description
本発明は、寒冷期に道路の舗装面上に氷膜が出来、走行車輌がスリップ事故を起こすのを防ぐ工法及びこれに用いる資材に関する。 The present invention relates to a construction method for preventing an ice film from being caused on a pavement surface of a road in a cold season and causing a traveling vehicle to cause a slip accident, and a material used therefor.
従来の舗装路面の凍結防止工法としては、舗装路面に一定間隔で溝を切削し、ここにウレタン樹脂を充填して硬化させる方法(特許文献1)、アスファルト舗装面の形成時にその表面にゴムチップを散布する方法(特許文献2)、舗装面に熱可塑性樹脂と凍結防止剤と滑り止め骨材とを含む表示材を塗布する方法(特許文献3)などが存在する。
上記諸特許文献に示されている工法は、舗装路面の切削、転圧、加熱等の専用機械を必要としたり、使用材料の調合、充填、硬化などの手間及び時間を必要とするなどの不便があり、作業性が悪く熟練を要する等の問題もあった。 The construction methods described in the above patent documents require inconveniences such as requiring dedicated machines for cutting, rolling, and heating the paved road surface, and requiring labor and time for preparing, filling, and curing the materials used. There were also problems such as poor workability and skill.
本発明の工法は、コンクリートまたはアスファルトよりなる道路基盤上に、粘着性のシートを貼着するものである。このシートは、ブチルゴムを含むゴム物質に、軟化剤などの配合材を加えたものである。 The construction method of the present invention is to stick an adhesive sheet on a road base made of concrete or asphalt. This sheet is obtained by adding a compounding material such as a softening agent to a rubber substance containing butyl rubber.
上記シートは厚さが1〜5mm、幅が30〜100mmで、上記基盤上に150〜300mmの間隔で貼着し、その表面にけい砂、細粒状の凍結防止剤などを散布することにより、直ちに車輌の走行が可能となる。 The sheet has a thickness of 1 to 5 mm and a width of 30 to 100 mm, and is adhered to the base at intervals of 150 to 300 mm, and by spraying silica sand, fine granular antifreeze, etc. on the surface, The vehicle can immediately run.
上記ゴム物質としては、ブチルゴムまたはこれに他種のゴムを混和したものや、タイヤ、チューブ等から再生した他種のゴムを含有するブチルゴムを使用し、これに常用の充填材や軟化剤などの配合材を混和したものである。充填材としては、炭酸カルシウム、タルク、カオリン、クレー、硫酸バリウム、けい藻土など、常用のゴム充填材を必要に応じて使用する。上記軟化剤としては、ロジンや石油系樹脂など固形物質と、ポリブテン油やプロセスオイルなど液状物質とを併用することが望ましい。 As the rubber material, butyl rubber or a mixture of other types of rubber with this, or butyl rubber containing other types of rubber regenerated from tires, tubes, etc., is used. It is a mixture of ingredients. As the filler, a conventional rubber filler such as calcium carbonate, talc, kaolin, clay, barium sulfate or diatomaceous earth is used as necessary. As the softening agent, it is desirable to use a solid substance such as rosin or petroleum resin and a liquid substance such as polybutene oil or process oil in combination.
本発明の凍結防止工法を施こした舗装路面上に薄く氷結層が出来た場合、その上を車輌が走行すると氷層が割れ、次々に後続車輌が通過する度に氷層は細片となって飛散し、数10台通過した後はタイヤの軌跡上には氷層が全く存在しなくなる。 When a thin icing layer is formed on the paved road surface subjected to the anti-freezing method of the present invention, the ice layer breaks when the vehicle travels on the surface, and the ice layer becomes a thin piece every time the following vehicle passes one after another. After several tens of vehicles are scattered, there is no ice layer on the tire track.
しかもその工法は、路面の切削。転圧、加熱等の専用機械を必要とせず、単にアスファルト、コンクリート等の路面上に粘着性シートを貼着するだけで足り、施工後は直ちに車輌を走行させることができるので、その経済的効果は極めて大きい。しかも施工した粘着性シートの路面からの突出量は5mm以内の小さなものであるために、その上を通過する車輌には衝撃が殆ど無い。 And the construction method is road surface cutting. It does not require special machines such as rolling and heating, it is sufficient to simply stick an adhesive sheet on the road surface of asphalt, concrete, etc., and the vehicle can run immediately after construction, so its economic effect Is extremely large. Moreover, since the protruding amount of the constructed adhesive sheet from the road surface is a small one within 5 mm, there is almost no impact on the vehicle passing over it.
調合された粘着物質は厚さ1〜5mm、望ましくは1〜3mmに展伸され、片面に離型紙が貼合わされ、幅30〜100mm、望ましくは50mmのテープ状に裁断し、巻回して商品とする。施工に際しては、アスファルト、コンクリート等の路面を乾燥させ、かつ清掃して上記粘着物質テープを車輌走行方向に150〜300mm、望ましくは200〜250mm間隔で平行に貼付ける。その際、路面に細かい砂や塵が残っている場合は、プライマーを塗布してから粘着物質テープを貼付ける。 The prepared adhesive substance is stretched to a thickness of 1 to 5 mm, preferably 1 to 3 mm, a release paper is pasted on one side, cut into a tape shape with a width of 30 to 100 mm, preferably 50 mm, and wound into a product. To do. At the time of construction, the road surface of asphalt, concrete or the like is dried and cleaned, and the above-mentioned adhesive material tape is applied in parallel in the vehicle running direction at intervals of 150 to 300 mm, preferably 200 to 250 mm. At that time, if fine sand or dust remains on the road surface, apply the adhesive tape after applying the primer.
貼付けた粘着物質テープは、離型紙の上から足で踏むなどして軽く押圧することにより、路面に結合させることができる。離型紙を剥離して除去した後、粘着物質がタイヤに付着するのを防ぐために、粘着物質テープの上に砂または砂状の凍結防止剤(塩化カルシウム、酢酸カルシウムマグネシウム等)を散布し、過剰分は、掃などにより除去して施工を完了する。 The adhered adhesive tape can be bonded to the road surface by lightly pressing it with a foot on the release paper. After removing the release paper, remove sand or sand-like antifreezing agent (calcium chloride, calcium magnesium acetate, etc.) on the adhesive tape to prevent the adhesive from adhering to the tire. The portion is removed by sweeping or the like to complete the construction.

上記粘着物質は厚さ2mmのシートに展伸し、離型紙を貼合せて幅50mmに裁断し、施工用の粘着物質テープを得た。この粘着テープを長さ1mに切断し、アスファルト舗装路面上に車輌走行方向に20cmの中心間隔で並べて貼着し、更に50cmの距離を置いて同様に粘着物質テープを並べて貼着し、これを車輌走行方向に繰返して施工した。 The pressure-sensitive adhesive substance was spread on a sheet having a thickness of 2 mm, and a release paper was pasted and cut into a width of 50 mm to obtain a pressure-sensitive adhesive tape for construction. Cut this adhesive tape to a length of 1m, and stick it on the asphalt pavement surface with 20cm center distance in the vehicle running direction, and put the adhesive substance tape in the same way at a distance of 50cm. The construction was repeated in the vehicle running direction.

◎印: 非常に効果あり
車輪の走行により氷層が大きく亀裂し、40〜50台走行した時点で氷層は 細粒化され、100台以上走行することによって氷層粒子が周囲に飛散して、軌 跡上に全く残らなかった。
○印: 車輪が70〜80台走行した時点で氷層が細粒化され、200台以上走行し ないと氷層粒子は飛散し盡さなかった。
△印: 車輪の走行によって氷層に亀裂が出来るが、数百台以上走行しないと氷層粒 子が残った。
×印: 車輪の走行により氷層は殆ど亀裂しなかった。
An ice layer having a thickness of 3 mm was formed on the constructed road surface, and a wheel on which a load of about 1 kgf / cm 2 (normal vehicle load) was applied was run on the ice layer. As a result, large cracks occurred in the ice layer. On the test road, an ice layer was formed as described above, and a vehicle was run on the ice layer, and the determination was made as follows based on the result received by the ice layer.
◎: Very effective
The ice layer is greatly cracked by the running of the wheels, and when it travels 40 to 50 units, the ice layer is finely divided. By running 100 units or more, the ice layer particles are scattered around and remain on the track at all. There wasn't.
○ mark: The ice layer was fined when the wheel traveled from 70 to 80 units, and the ice layer particles did not scatter and disappear unless the vehicle traveled more than 200 units.
△ mark: The ice layer cracked by running the wheel, but the ice layer particles remained if it did not run more than a few hundred.
X mark: The ice layer hardly cracked by running of the wheel.
