以下、実施例に沿って説明する。   Hereinafter, it demonstrates along an Example.
溶融(液体)ブロンアスファルトを使用した場合。
この製造方法の重要加工工程は、潤滑油廃液と溶融ブロンアスファルトとを混合させたことである。以下に舗装及び防水層のひび割れ・穴等の補修材の製造方法を工程に沿って説明する。
1)常温の潤滑油廃液と針入度20〜30で温度約180℃前後の溶融ブロンアスファルトとを混合し、必要に応じて添加量を調整し、同時に添加材を徐々に添加する。
空の加熱式撹拌混合タンクヘ、常温の潤滑油廃液と針入度20〜30、温度約180℃前後となる溶融ブロンアスファルトとを、予め吐出量を設定した各々のギヤポンプにより移送し、加熱撹拌混合をする。温度は160〜190℃の範囲内とし、最適には約180℃前後を保ちながら約1〜2時間、加熱撹拌混合を続ける。
潤滑油廃液とブロンアスファルトの混合割合は、ブロンアスファルトの重量に対して潤滑油廃液を10〜25重量%添加する。
上記各材料の個別状態及び混合割合や温度設定であれば、従来の製造方法によって得られた潤滑油廃液と溶融ブロンアスファルトとの混合物とは異なり、ブロンアスファルトを徐々に、且つ均一に軟化させることができ、良好な混合物が得られる。
上記製造工程の特徴は、単独では舗装や防水層の補修材には不可能なブロンアスファルトを、潤滑油廃液で軟化し、所要の粘度にして良好な補修材を得ることを可能とした工程である。

その2、一般的に行われていないが、不揮発油によるフラックス(fluxing)法で、不揮発油・不乾性油(潤滑油など)を混合して所要の粘度にして施工しやすくする。施工後、不揮発油・不乾性油(潤滑油など)は蒸発しないので元のアスファルト性状には戻らない。
本実施例では、後者のブロンアスファルトと潤滑油廃液を混合する軟化手段を採用している。
When molten (liquid) bron asphalt is used.
An important processing step of this manufacturing method is that the lubricating oil waste liquid and molten bron asphalt are mixed. Below, the manufacturing method of repair materials, such as a crack and a hole of a pavement and a waterproofing layer, is demonstrated along a process.
1) Lubricating oil waste liquid at normal temperature and molten bronze asphalt with a penetration of 20 to 30 and a temperature of about 180 ° C. are mixed, the addition amount is adjusted as necessary, and the additive is gradually added at the same time.
Transfer to the empty heated agitation and mixing tank, normal temperature lubricating oil waste liquid and 20 to 30 penetrations of molten bronze asphalt at a temperature of about 180 ° C. with each gear pump set in advance, and mix by heating and mixing. do. The temperature is in the range of 160 to 190 ° C., and optimally, stirring and mixing is continued for about 1 to 2 hours while maintaining around 180 ° C.
The mixing ratio of the lubricating oil waste liquid and bron asphalt is 10 to 25% by weight of the lubricating oil waste liquid based on the weight of bron asphalt.
Unlike the mixture of lubricating oil waste liquid and molten bronze asphalt obtained by the conventional manufacturing method, the bron asphalt can be softened gradually and uniformly as long as it is the individual state and mixing ratio and temperature setting of the above materials. And a good mixture is obtained.
The characteristic of the above manufacturing process is a process that makes it possible to soften Bron asphalt, which cannot be used alone as a repair material for pavement and waterproof layers, with lubricating oil waste liquid to obtain a desired repair material with the required viscosity. is there.
In general, the following two methods can be considered as means for softening asphalt.
First, gasoline, kerosene, light oil, etc. are mixed by the cut-back method with light oil to make the required viscosity easy to install. After construction, the light oil can be returned to its original asphalt properties even after evaporation.
Second, although not generally performed, non-volatile oil and non-drying oil (such as lubricating oil) are mixed by a fluxing method using non-volatile oil to obtain a required viscosity for easy installation. After construction, non-volatile oil and non-drying oil (such as lubricating oil) will not evaporate and will not return to the original asphalt properties.
In this embodiment, a softening means for mixing the latter bron asphalt and the lubricating oil waste liquid is employed.
2)上記工程の間、スチレン・ブタジエン系熱可塑性エラストマーを潤滑油廃液とブロンアスファルトとの混合中に少しずつ添加し、加熱撹拌融解混合して所要の性状にする。各原材料の添加は約1〜2時間かけてほぼ同時に終了する。 2) During the above process, a styrene / butadiene thermoplastic elastomer is added little by little during mixing of the lubricating oil waste liquid and bron asphalt, and the mixture is heated and stirred to melt and mixed to the required properties. The addition of each raw material is completed almost simultaneously over about 1-2 hours.
3)その後、約1時間前後、加熱撹拌融解混合し、上記工程での撹拌融解混合時間と合わせて約3時間を目安にして性状変化を観察・確認する(一次加工)。
上記温度は160〜190℃の範囲とし、最適には約180℃前後を保ち続ける。
スチレン・ブタジエン系熱可塑性エラストマーの混合割合は、ブロンアスファルトの量に対して5〜10重量%添加する。この添加により、混合物に一層の粘弾性・可撓性・耐衝撃性・塑性変形等の低温特性が加わり、補修材の性能を大幅に向上させることができる。
3) Then, heat stirring and melting and mixing for about 1 hour, and observing and confirming the property change for about 3 hours together with the stirring and melting and mixing time in the above step (primary processing).
The temperature is in the range of 160 to 190 ° C, and optimally keeps around 180 ° C.
The mixing ratio of the styrene / butadiene-based thermoplastic elastomer is 5 to 10% by weight with respect to the amount of bron asphalt. By this addition, low temperature characteristics such as viscoelasticity, flexibility, impact resistance and plastic deformation are added to the mixture, and the performance of the repair material can be greatly improved.
4)その後、温度を160〜190℃、最適には約180℃前後を保ちながら消石灰を徐々に少量ずつ添加して加熱撹拌混練する。添加後、加熱撹拌混練時間は約3時間を目安として混合物の仕上がりを判断する(二次工程)。
消石灰の混合割合は、潤滑油廃液とブロンアスファルトの量に対して20〜40重量%とし、徐々に添加して加熱撹拌混練する。消石灰の添加により粘弾性を高め、感温性を小さくすることができる。それにより自然温度下において流動しようと働く力に対して流れまいとする力が強く働く。このような性状は舗装及び防水層の補修材にとっては欠かせない重要な性能であり、補修施工後の耐用年数の長期化に大きく影響する。それによりライフサイクルコストの低減をはかり、経済効果を引き出すという重要な役割を達成することができる。
なお、アルカリ性であるので、路面や骨材への付着性を一層向上させることができる。
4) Thereafter, slaked lime is gradually added little by little while keeping the temperature at 160 to 190 ° C., optimally around 180 ° C., and kneaded with heating and stirring. After the addition, the heat stirring and kneading time is determined by taking about 3 hours as a guide (secondary step).
The mixing ratio of slaked lime is 20 to 40% by weight with respect to the amount of lubricating oil waste liquid and bron asphalt, and is gradually added and kneaded with heating and stirring. By adding slaked lime, viscoelasticity can be increased and temperature sensitivity can be reduced. As a result, the force to flow against the force that tries to flow under natural temperature works strongly. Such a property is an important performance that is indispensable for repair materials for pavement and waterproof layers, and greatly affects the prolongation of the service life after repair work. As a result, the important role of reducing the life cycle cost and bringing out the economic effect can be achieved.
In addition, since it is alkaline, the adhesiveness to a road surface or an aggregate can be improved further.
5)上記混合物の仕上がり後、剥離材を施した容器内に該混合物の一定量を流し込み、自然冷却する。
6)上記工程の翌日等の冷却後、容器内から混合物を分離して取り出し、所定の大きさに切断ないしは砕く(三次工程)。切断は常温で行い、砕く場合には冷蔵庫で0〜−5℃まで温度を下げて行う。

上記製造方法により得た補修材は、単独での補修材の他、上記実施例1、2の補修材に先行して施工する常温施工型のひび割れ補修用注入充填材としての役割をも成すことができる。この場合、補修用注入充填材は、施工場所において自然流下するために舗装ひび割れの間隙の狭い(1〜3mm)深部まで注入充填でき、上記微細な間隙や空洞を充填することが可能となった。
更に、加熱溶融した上記実施例1、2の補修材を流し込み、ひび割れを注入皮膜形成することにより、先に注入充填した補修用注入充填材と接触して一体化され、粘着性が高められ、橋渡し現象が起きなく、ひび割れの充填が完成する。その結果、毛細水の上昇を抑制することができ、破損の進行を抑制し補修効果は一層大きくなった。
なお、アスファルト舗装の場合は、ひび割れにより劣化した面のアスファルト分を活性化することができる。コンクリート舗装の場合は、ひび割れに充填したことにより、ポンピング現象を抑制して路盤からのシルト分の舗装表面への吹出し防止及び更なる路盤の空洞化を防ぐことができる。
また、注入充填した補修用注入充填材は、年間を通じて適度の粘弾性を保持することができ、補修効果の持続性向上を図ることができる。
上記理由により、舗装ひび割れ進行の主な原因の一つである雨水(表面水)が、ひび割れに滲入することにより舗装に及ぼす破損の影響が大であるが、上記実施例によって製造された補修材は雨水(表面水)の滲入の防止が図れることはもとより、路床路盤からの毛管水による上昇や寒冷時のひび割れ内の凍上及び融解の繰り返しを防ぎ、ひび割れの進行を抑制することができるため、舗装の予防維持を含め維持管理費の低減が図れ、大きな経済効果をもたらすものである。

The repair material obtained by the above manufacturing method also serves as an injection filling material for crack repair of a normal temperature construction type to be applied prior to the repair material of Examples 1 and 2 above, in addition to a single repair material. Can do. In this case, the filling material for repairing can flow down to a narrow (1-3 mm) deep part of the gap of the pavement crack in order to flow down naturally at the construction site, and it has become possible to fill the fine gaps and cavities. .
Furthermore, by pouring the repair material of the above-mentioned Examples 1 and 2, which has been heated and melted, and forming an injection film with cracks, it is integrated in contact with the repair injection filler previously injected and filled, and the adhesiveness is improved. Bridging is completed without bridging. As a result, the increase in capillary water can be suppressed, the progress of breakage is suppressed, and the repair effect is further increased.
In addition, in the case of asphalt pavement, the asphalt content of the surface deteriorated by the crack can be activated. In the case of concrete pavement, by filling the crack, it is possible to suppress the pumping phenomenon and prevent the silt from the roadbed from being blown onto the pavement surface and further preventing the hollowing of the roadbed.
In addition, the filling material for repairing that has been infused and filled can maintain appropriate viscoelasticity throughout the year and can improve the sustainability of the repairing effect.
For the above reasons, rainwater (surface water), which is one of the main causes of pavement crack progression, has a large impact on pavement by infiltrating into the crack, but the repair material manufactured by the above example In addition to preventing intrusion of rainwater (surface water), it is possible to prevent the water from rising due to capillary water from the roadbed and the repeated freezing and thawing of cracks in cold weather, and to suppress the progress of cracks. Therefore, the maintenance cost including the preventive maintenance of pavement can be reduced, which brings about a great economic effect.
In addition, it retains moderate viscoelasticity and stability in the crack and has excellent durability both in the cold season in winter and at the high temperature in summer.
上記実施例1乃至3によって製造された補修材を舗装及び防水層のひび割れや穴等に適用する場合の補修方法について以下にその実施例を示す。   Examples of repairing methods in the case where the repair material manufactured in Examples 1 to 3 is applied to cracks and holes in pavement and waterproof layers will be described below.
ひび割れを補修する(リフレクションクラック(reflection crack)抑制)塗膜工法。
亀甲状ひび割れを補修する場合、その亀甲状ひび割れ面に約3〜4mmの厚さに塗膜層を形成する。これにより既設の亀甲状ひび割れが新しい補修箇所となった塗膜層に伝播(リフレクションクラック)されてその新しい補修箇所に亀甲状ひび割れが生じることを抑制することができる。
この塗膜層は交通荷重による応力の緩和層、路床・路盤からの毛管水の遮断層、及び既設面との接着層としての役目を果たし、ひび割れを抑制することができる。
A coating method that repairs cracks (suppresses reflection cracks).
When repairing a turtle shell crack, a coating layer is formed on the turtle shell crack surface to a thickness of about 3 to 4 mm. As a result, it is possible to prevent the existing turtle shell crack from being propagated (reflection crack) to the coating layer that has become a new repair site, and the generation of the turtle shell crack at the new repair site.
This coating layer serves as a stress relaxation layer due to traffic load, a blocking layer of capillary water from the road bed / base, and an adhesive layer with the existing surface, and can suppress cracks.
コンクリート床板・鋼床版等の橋床版や構築物の防水層への塗膜工法。
コンクリート床版の不陸や凹凸面、及び鋼床版の溶接部やリベット部の接続部等に容易に塗膜形成することができ、確実で信頼性の高い防水層が完成できる。
Coating method for waterproofing layers of bridge decks and structures such as concrete floor boards and steel decks.
A coating film can be easily formed on the uneven surface and uneven surface of the concrete slab, and the welded portion of the steel slab and the connecting portion of the rivet portion, and a reliable and highly reliable waterproof layer can be completed.
ひび割れへのシールにより雨水(表面水)などの滲入防止、シール工法。
本発明によって製造された補修材の材料特性により、舗装面に使用した場合、5分後には交通開放ができるため交通渋滞を緩和することができる。
また、夏季高温時に補修材が溶け出すこと(フラッシュ現象)がない。従来のゴム系のシール材には溶け出すものが多かった。
更に、冬季寒冷時においても、粘弾性があり、塑性変形を繰り返し、舗装面の場合はタイヤチェーン等による摩耗は生じるものの、衝撃により砕かれての飛散はなく、耐衝撃性に優れている。
Sealing method to prevent infiltration of rainwater (surface water) by sealing against cracks.
Due to the material properties of the repair material produced according to the present invention, when used on a paved surface, traffic can be relieved after 5 minutes, thereby reducing traffic congestion.
In addition, the repair material does not melt (flash phenomenon) at high temperatures in summer. Many of the conventional rubber-based sealing materials melted out.
Further, even during cold weather in winter, it has viscoelasticity and repeats plastic deformation. In the case of a pavement surface, wear due to a tire chain or the like is generated, but there is no scattering due to impact and excellent impact resistance.
穴埋め材としての現場練り施工方法。
排水性及び透水性舗装並びに一般舗装・防水層等の様々な態様に対応することができる。
舗装や防水層の種類に合わせて現場練りにより穴埋め材を造り、施工することができる。
本発明によって製造された補修材と各寸法別の骨材を用意しておき、現場で加熱混練して穴埋めする。補修材の量と骨材の量を変えることにより、透水性及び不透水性のいずれの穴埋めにも対応することのできる穴埋め材を得ることができる。
アスファルト舗装、コンクリート舗装或いは他の舗装や防水層を含め、いずれの穴埋めにも適切に対応することができる。
また、粘性の高い補修材なので、現場において加熱混練して穴埋めすることができ、施工後の耐用年数は従来の常温混合材とは比較にならない程長い。交通安全上及び舗装や防水層の維持管理費を低減する意味からも優れている補修材を得ることができる。特に交通量の多い路線の補修に向いている。
更に、舗装面に使用した場合、従来の補修材は常温混合材(常温で施工できる混合物)が一般的に使われているので、雨天が多く続いた場合は交通車両に飛散され、再補修を繰り返している。従って、再度生じた穴によりバイクの転倒事故が多発している。このようなことは交通の安全を確保する面からも問題があった。また、再補修の繰り返しでは舗装の維持管理費は高くなり、不経済であった。強いて言えば従来の補修材は交通量の少ない路線の補修にしか対応できないものであった。
On-site kneading construction method as hole filling material.
Various modes such as drainage and water-permeable pavement and general pavement / waterproof layer can be dealt with.
A hole filling material can be made and constructed by on-site mixing according to the type of pavement and waterproof layer.
The repair material manufactured according to the present invention and the aggregates for each dimension are prepared, and they are heated and kneaded on site to fill the holes. By changing the amount of the repair material and the amount of the aggregate, it is possible to obtain a hole filling material that can cope with both water-permeable and water-impermeable hole filling.
Any hole filling, including asphalt pavement, concrete pavement or other pavement or waterproof layer, can be handled appropriately.
In addition, since it is a highly viscous repair material, it can be heated and kneaded at the site to fill the hole, and its useful life after construction is so long that it cannot be compared with a conventional normal temperature mixed material. An excellent repair material can be obtained in terms of traffic safety and from the viewpoint of reducing maintenance costs for pavement and waterproofing layers. It is especially suitable for repairing routes with heavy traffic.
Furthermore, when used on pavement surfaces, conventional repair materials are generally used at room temperature (a mixture that can be applied at room temperature), so if it rains a lot, it will be scattered on traffic vehicles and repaired. It is repeating. Therefore, motorcycle accidents frequently occur due to the holes generated again. This was a problem in terms of ensuring traffic safety. Also, repeated re-repairs resulted in high pavement maintenance costs, which was uneconomical. In other words, conventional repair materials can only deal with repairs on routes with low traffic.
段差を原因とする振動を軽減する(地域住民の苦情処理)塗膜工法。
施工の継ぎ目や構造物に生じているわずかな段差(10mm前後)により、交通車両の通過時に生じる振動を本発明によって製造された補修材の材料特性(粘弾性と塑性変形)によりゼロすり付けが可能で、上記振動を生じさせなくすることができる。本発明の製造方法によって得られた補修材は、従来の舗装材では不可能な有効的な段差修正ができる。
振動が起きている付近の住民からの夜眠れない、幼児がびくびくして落ち着かない、家の屋内の壁にひび割れが生じた等の苦情或いは自動車のドライバーからの精密機械が破損した等の苦情が道路管理者に寄せられていたが、それらを解決することが可能となった。
Coating method to reduce vibration caused by steps (complaint processing for local residents).
Due to the slight steps (around 10mm) that occur in construction seams and structures, the vibrations that occur when passing traffic vehicles can be zero rubbed due to the material properties (viscoelasticity and plastic deformation) of the repair material manufactured according to the present invention. It is possible to eliminate the above vibration. The repair material obtained by the manufacturing method of the present invention can correct an effective level difference that is impossible with conventional paving materials.
Complaints such as inability to sleep at night from residents in the vicinity of vibrations, toddlers being shy and restless, cracks in the interior walls of the house, or damage to precision machinery from automobile drivers It was sent to the road administrator, but it became possible to solve them.
上記いずれの施工においても上記実施例3の補修用注入充填材そのものの使用或いは実施例1、2のものに先だって施工し、それに併用することが可能である。
本発明によって得られた補修材となる補修用注入充填材は、特に流動特性が極めて良好となり、ひび割れに自然流下するので機械による圧力での注入は必要なくなった。また、容器からポリ製の油差し(オイル差し)や家庭で農薬散布するような簡易手噴霧器などに詰め、ひび割れに注入して自然流下する様子を見ながら、誰にでも施工することのできる補修材を提供することが可能となった。
更に、補修用注入充填材は自然流下するのでひび割れ箇所にしっかり収まり、それ以上路面に膨れ上がることはなく、誰が施工しても施工品質が一定に保たれる特長を有している。
その後、加熱溶融した実施例1、2の補修材を流し込み、ひび割れを皮膜形成する。
施工後、直ぐに交通開放できるため、工事による交通渋滞を最小限にとどめることができる。
In any of the above constructions, it is possible to use the repair injection filler material of the third embodiment itself or to construct it prior to the first and second embodiments, and use it together.
The filling material for repair, which is a repair material obtained by the present invention, has particularly good flow characteristics and naturally flows down into cracks, so that it is not necessary to inject under pressure by a machine. In addition, it is packed in a plastic oil bottle (oil bottle) or a simple hand sprayer that sprays agricultural chemicals at home, and repaired so that anyone can install it while watching it flow into a crack and flow down naturally. It became possible to provide materials.
Furthermore, since the filling material for repairing flows down naturally, it fits firmly in the cracked part, and does not swell further on the road surface, so that the construction quality can be kept constant regardless of who constructs it.
Then, the repair material of Examples 1 and 2 which has been heated and melted is poured to form a film of cracks.
Since traffic can be opened immediately after construction, traffic congestion due to construction can be minimized.
