【発明の詳細な説明】
（産業上の利用分野）
本発明は、床版上に防水層を介して舗装材を敷設して舗
装する方法に関するもので、橋梁や高架道路の建設、補
修をする場合に利用される。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method of paving by laying a paving material on a deck slab through a waterproof layer, and is used for constructing and repairing bridges and elevated roads. Used in cases.
（従来技術とその問題点）
橋梁や高架道路は、路床を構成するコンクリート製、鋼
板製等の床板の上に舗装層が形成されているが、路面上
の雨水が舗装層のクランクや隙間から裏面側へ到達し、
これが床版、桁、支柱等に侵入して、鉄筋を腐食させた
り、構造物を劣化させる原因となっている。(Prior art and its problems) Bridges and elevated roads have a pavement layer formed on the concrete, steel plate, etc. floor plates that make up the roadbed. to reach the back side,
This infiltrates floor slabs, girders, supports, etc., causing corrosion of reinforcing bars and deterioration of structures.
特に、橋梁や高架道路が海岸の近くや積雪地帯に設けで
ある場合には、塩分の多い雨が降ったり、融氷剤の塩分
（ＣａＣ１ｚやＮａＣ１等）が融けて水に混ざるため、
これらが床版、桁、柱等に侵入することによって鉄筋の
腐食を助長する結果となる。In particular, if a bridge or elevated road is built near the coast or in a snowy area, rain with a high salt content may fall, and salts from ice-melting agents (CaC1z, NaC1, etc.) may melt and mix with the water.
These intrude into floor slabs, girders, columns, etc., resulting in accelerated corrosion of reinforcing bars.
そのために、床版上に合成ゴム溶液を塗布乾燥させたり
、ゴムアスファルトシートを貼着したり、或いは、エポ
キシ樹脂を塗布する等して舗装層との間に防水層を設け
ることによって、舗装層から侵入する水分の遮断が図ら
れている。To this end, the pavement layer can be coated with a waterproof layer by applying a synthetic rubber solution on the floor slab and drying it, pasting a rubber asphalt sheet, or applying an epoxy resin between the pavement layer and the pavement layer. It is designed to block moisture from entering.
しかしながら、これらの防水層の形成は、以下に述べる
ように、いずれも作業性が悪く、また、機能上も不十分
なものであった。However, as described below, the formation of these waterproof layers has poor workability and is also insufficient in terms of functionality.
合成ゴム溶液を塗布乾燥させる場合には、塗布後有機溶
剤が残留した状態で舗装材を敷設してしまうと、溶剤の
影響によって路面にプリスターが発生するため、塗膜を
長時間放置しておく必要があり、作業能率が著しく悪く
なる。When applying and drying a synthetic rubber solution, if the paving material is laid with organic solvent remaining after application, pristers will occur on the road surface due to the effects of the solvent, so leave the paint film for a long time. If necessary, work efficiency will be significantly reduced.
また、アスファルトシートを貼着させる場合には、床版
とシートとの間に気泡が残留するのを避けられず、気泡
の豚腸が床版と舗装層とを剥離させたり、舗装層を押し
上げて路面にフクレを発生させたりする原因となる。In addition, when asphalt sheets are attached, it is unavoidable that air bubbles remain between the floor slab and the sheet, and the air bubbles may cause the floor slab and pavement layer to separate or push up the pavement layer. This may cause blisters on the road surface.
更に、エポキシ樹脂を塗布して防水層を形成する場合に
は、樹脂を塗布して硬化させた後に舗装工程に入るため
、長時間にわたって道路を閉鎖しなければならない不都
合がある。樹脂の硬化前に舗装をする場合には、未硬化
の樹脂上での作業となるため、作業性も悪く防水膜の均
一性を保てなくなる。Furthermore, when a waterproof layer is formed by applying an epoxy resin, the paving process begins after the resin is applied and cured, resulting in the inconvenience that the road must be closed for a long period of time. When paving is performed before the resin hardens, the work is performed on unhardened resin, which results in poor workability and makes it impossible to maintain the uniformity of the waterproof membrane.
このように、層間剥離が生じたり、一定の膜厚を確保で
きないと、防水層の防水機能が失われ、路面上の雨水が
容易に床版、桁、柱等の内部にまで侵入して、これらの
劣化を助長乃至促進してしまうことになる。In this way, if delamination occurs or a certain film thickness cannot be maintained, the waterproof function of the waterproof layer will be lost, and rainwater on the road surface will easily penetrate into the interior of slabs, girders, columns, etc. This will encourage or accelerate these deteriorations.
（技術的課題）
本発明は、床版上に防水層を介して舗装材を敷設し舗装
する方法において、防水層の床版及び舗装層に対する接
着機能に耐久性を持たせることを課題としたものである
。(Technical Problem) The present invention aims to provide durability to the adhesion function of the waterproof layer to the floor slab and the pavement layer in a method of paving by laying paving material on the floor slab via a waterproof layer. It is something.
（技術的手段）
この技術的課題を解決するための技術的手段は、
（イ）防水層をゴム弾性のあるホントメルト防水材を溶
融塗布して形成し、
（ロ）その上に加熱された舗装材を敷設すること、
である。(Technical means) The technical means for solving this technical problem are: (a) forming the waterproof layer by melt-coating a rubber-elastic real-melt waterproofing material; This is the laying of paving materials.
（技術的手段の作用）
ホットメルト防水剤を溶融して床版上に塗布すると、こ
の段階で防水材は流動性を持っているために、床版面の
微細な凹凸やクランク更にはその他の隙間へ容易に進入
してこれらを覆うと共に、直ちに大気によって冷却され
て固化し、床版上に防水層が形成される。(Effect of technical means) When hot-melt waterproofing agent is melted and applied to the floor slab, the waterproofing material has fluidity at this stage, so it can be easily absorbed by minute irregularities on the floor slab surface, cranks, and other gaps. It easily penetrates and covers them, and is immediately cooled and solidified by the atmosphere, forming a waterproof layer on the floor slab.
その上に加熱された舗装材を敷設すると、ホコ・トメル
ト防水材で構成される防水層の表面は、舗装材の熱によ
って再び溶融し、舗装材が冷却された段階で再び固化し
、舗装材と床版とが強力に接着される。When heated paving material is laid on top of it, the surface of the waterproof layer made of Hoko-Tomelt waterproofing material melts again due to the heat of the paving material, solidifies again when the paving material cools, and the paving material and the floor slab are strongly bonded.
ホントメルト防水材はゴム弾性を持っているために、車
両の走行によって床版が振動したり、床版にクランクが
発生したり、若干の歪みが生じたりしても、防水材は追
随することができ、防水層自体にクランクが生ずること
がない。Honmelt waterproof material has rubber elasticity, so even if the floor slab vibrates, cranks, or is slightly distorted when the vehicle is running, the waterproof material will follow suit. This prevents cranking of the waterproof layer itself.
従って、防水層の床版及び舗装層に対する接着力は、耐
久性を持つことになる。Therefore, the adhesive strength of the waterproof layer to the floor slab and pavement layer is durable.
（本発明の効果）
防水層の接着力に耐久性を持たせられる結果、路面上の
水が床版側へ移行するのを完全に阻止できるため、ｉａ
梁や高架道路の路床、支持柱、桁等の劣化を防止するこ
とができ、橋梁や高架道路の耐久性を向上できる利点が
ある。(Effects of the present invention) As a result of making the adhesive strength of the waterproof layer durable, it is possible to completely prevent water on the road surface from migrating to the floor slab side.
It is possible to prevent deterioration of the roadbed, support columns, girders, etc. of beams and elevated roads, and has the advantage of improving the durability of bridges and elevated roads.
溶融塗布したホットメルト防水材は、大気によって早急
に冷却されるために防水層は短時間で形成される利点が
ある。そのため、防水層の形成及び防水層上での作業を
直ちに行えるため、舗装作業時間が極めて短縮化され、
道路の閉鎖時間も大幅に短縮できる利点がある。Hot-melt waterproofing materials applied by melting have the advantage that a waterproof layer can be formed in a short time because they are rapidly cooled by the atmosphere. Therefore, the formation of the waterproof layer and the work on the waterproof layer can be done immediately, which greatly shortens the paving work time.
This has the advantage of significantly reducing road closure time.
このことは、舗装層の敷設が遅れることがあっても、そ
れ迄は道路解放が可能となることを意味し、交通渋滞の
解消にも寄与できる利点がある。This means that even if the laying of the pavement layer is delayed, the road can be kept open until then, which has the advantage of contributing to relieving traffic congestion.
（実施態様）
」−記の舗装材としては、アスファルトコンクリートが
好適である。(Embodiment) Asphalt concrete is suitable as the paving material.
この舗装材は、１６０°Ｃ程度に加熱された状態で現場
に搬入され、路面に敷設された段階で１００〜１１０’
Ｃ位に冷却させられる（寒冷地では９０’Ｃ程度になる
こともある）。This paving material is heated to about 160°C and delivered to the site, and when it is laid on the road surface it has a temperature of 100 to 110°
It is cooled to about 90°C (in cold regions it can reach about 90°C).
他方、気温が３７〜３８°Ｃの状態では路面の温度は６
５°Ｃに達することがある。On the other hand, when the air temperature is 37-38°C, the road surface temperature is 6
Temperatures may reach 5°C.
従って、ホットメルト接着剤の軟化点は、８０〜ｌｏｏ
’ｃの間に設定しておくのが望ましいことになる。Therefore, the softening point of hot melt adhesive is 80 to loo
It is desirable to set it between 'c'.
上記ホットメルト防水材としては、合成ゴムを主成分と
したホットメルト接着剤（例えばコニシ株式会社製の「
ポンドホットメルトＭ Ｕ ３４０シリーズ」・ｒＭＵ
２６０シリーズ」）等が好適であるが、その他のホット
メルト接着剤を使用しても良い。The above-mentioned hot-melt waterproofing material is a hot-melt adhesive whose main component is synthetic rubber (for example, Konishi Co., Ltd.'s "
