Abstract
Description
本発明は、道路等の舗装後に生じる表面の小穴、ひび割れ、角欠け或いは細くて比較的深い欠損部分等の小規模な欠損の補修工法で、補修現場において舗装用骨材に舗装部材を混練し、温度低下が生じる前に該欠損部分に流し込む舗装面の補修工法の分野に関するものである。 The present invention is a repair method for small-scale defects such as small holes, cracks, cracks in corners, or narrow and relatively deep defects that occur after paving on roads, etc., and the paving members are kneaded with the paving aggregate at the repair site. Further, the present invention relates to the field of repairing a pavement surface that is poured into the defective portion before a temperature drop occurs.
従来より、道路等の補修には、通常の全面舗装に使用している舗装材料と同一の材料を使用している。該舗装部材は、工場等の大規模な製造設備（アスファルトプラント）において、加熱したアスファルト（瀝青材）に舗装用骨材を混練して製造し、それらが硬化しないように温めた状態で現場に持ち込み、必要とする補修部分に使用していた。また、補修専用材料として常温で施工可能な高分子材料とアスファルト系組成物とを結合した材料が開発され、それらを補修部分に使用している。
上記のように、補修部分に使用する材料が全面舗装をする材料と同一材料の場合は、それらの材料は工場等の大規模な製造設備において製造され、それら材料を温めた状態を保持して補修現場に持ち込まなくてはならず、そのための設備を備えた運搬手段を必要とした。また、当該設備を備えたものでも遠方へ運搬することはできなかった。更に、小規模な補修であっても必要以上の使用しきれない大量の舗装材料が運び込まれ、残った舗装材料は、温度が低下して硬化し、結合力のなくなった舗装用残材料として製造工場へ持ち運ばれることになり、再生舗装混合物として再利用されたり、廃材として処理されている。このことは非経済的であると同時に、それらの置場や投棄場所が大きな問題となっていた。 As mentioned above, if the material used for the repair part is the same as the material to be fully paved, these materials are manufactured in large-scale manufacturing facilities such as factories, and the materials are kept warm. We had to bring it to the repair site, and we needed a means of transportation with equipment for it. Moreover, even those equipped with the equipment could not be transported far away. In addition, a large amount of pavement material that cannot be used more than necessary even if it is a small-scale repair is brought in, and the remaining pavement material is cured as the temperature drops and is manufactured as a pavement residue material that has lost its bonding strength It will be carried to the factory and reused as a recycled pavement mixture or treated as waste material. This was uneconomical and at the same time their storage and dumping locations became a major problem.
また、常温で施工可能な材料は、補修後に当初の舗装部分と補修部分とが分離し易いこと、及び高分子材料とアスファルト系組成物とが混合されているので、その使用期限は約６ヶ月程度であり、補修後に残った材料は、早期に変質硬化し、次回の補修現場には使用できないことが多く、上記同様、廃材として処理されていた。更に、高分子材料を使用しているので高価なものであった。 In addition, materials that can be constructed at room temperature are easy to separate the original pavement and repair parts after repair, and because the polymer material and the asphalt composition are mixed, the expiration date is about 6 months. The material remaining after the repair was deteriorated and hardened at an early stage and was often unable to be used at the next repair site, and was treated as waste as described above. Further, since a polymer material is used, it is expensive.
また、舗装面に生じた亀裂、マンホールや排水桝等の道路設置物の周囲に生じた隙間等の細くて深い欠損部分は、補修材料が当該部分に入り込まず表面のみが補修されるのみで上記従来の材料及び補修方法ではそれらに亀裂を生じすぐに分離し、再度の補修を繰り返さなければならなかった。
そのため、粘性を低くすることが考えられるが、それは材料劣化を促進し、亀裂を発生させる原因ともなっていた。更に、粘性が低いため、真夏日等の高温により溶け出す可能性も高かった。
In addition, for thin and deep defects such as cracks generated on the pavement surface and gaps around road installations such as manholes and drainage pits, the repair material does not enter the part and only the surface is repaired. In the conventional materials and repair methods, they have cracked and separated immediately and repeated repairs.
For this reason, it is conceivable to lower the viscosity, but this has promoted material deterioration and has also caused cracks. Furthermore, since the viscosity is low, the possibility of melting out at high temperatures such as midsummer days was high.
本発明は、上記従来技術の問題点を解決した舗装面の補修工法に関するもので、その具体的構成は、下記の工程よりなることを特徴とする。
１．補修用材料となる舗装用骨材を乾燥する。

上記配合例１ないし７はいままでの実験例であり、多少の配合割合を変えることにより、より優れた特性を有する舗装部材を実現する可能性を有している。 The above blending examples 1 to 7 are experimental examples so far, and have a possibility of realizing a pavement member having more excellent characteristics by changing some blending ratios.
上記舗装部材を、上記舗装用骨材と同様、袋に当該量を表記して袋詰めを行なう。 The pavement member is packed in a bag by indicating the amount in the same manner as the pavement aggregate.
上記袋詰めは、３ｋｇ、５ｋｇ、１０ｋｇ等となるように計量して行なう。それら袋詰めした該舗装用骨材及び舗装部材とを、補修を必要とする場所へ運搬する。 The bagging is carried out by weighing so as to be 3 kg, 5 kg, 10 kg or the like. The pavement aggregate and the pavement member packed in the bag are transported to a place requiring repair.
該舗装用骨材と舗装部材とは各々別々の袋に詰めるが、両者の混合割合に応じて予めセットにした状態で製造・管理することができる。
上記舗装部材の対舗装用骨材への混合割合は重量比で約５〜２５％の割合とすることが良好と考えられるので、上記セットもその割合に応じて予め袋詰めしておくことにより、現場での対応を早く且つ間違いなくすることができる。
The pavement aggregate and the pavement member are packed in separate bags, but can be manufactured and managed in a pre-set state according to the mixing ratio of the two.
Since it is considered that the mixing ratio of the paving member to the aggregate for paving is preferably about 5 to 25% by weight, the above set is also packed in advance according to the ratio. , Can respond quickly and definitely on site.
上記のように舗装用骨材と舗装部材との混合割合は大きな幅があるが、その要因は舗装機能によるところが大である。一般的な不透水性の舗装であれば舗装部材の割合が多くなるが、透水性のある排水性舗装の場合はその割合が少なくなる。 As described above, the mixing ratio of the aggregate for paving and the paving member has a wide range, but the factor is largely due to the paving function. In the case of general water-impermeable pavement, the ratio of the paving member is increased, but in the case of water-permeable drainage pavement, the ratio is decreased.
補修箇所となる欠損部分である小穴、幅の広いひび割れ、ハガレ箇所を特定し、当該部分の清掃を行ない、乾燥させる。 Identify the small holes, wide cracks, and peeled off parts that will be repaired parts, clean the parts, and dry them.
上記袋詰めされた舗装用骨材と舗装部材とを開封し、混合し、上記した約５〜２５％の割合で施工現場でプロパンガス及びバーナー等の加熱手段を用いて溶解釜等を使用し加熱混合する。加熱により舗装部材が溶解し、舗装用骨材の周囲に付着し、両者が混合され、補修用材料を得ることになる。 Open and mix the pavement aggregate and pavement member packed in the bag, and use a melting pot etc. using heating means such as propane gas and burner at the construction site at a rate of about 5 to 25% as described above. Mix by heating. The pavement member is melted by heating, adheres to the periphery of the aggregate for pavement, and both are mixed to obtain a repair material.
上記混合された補修用材料を、予め清掃された補修箇所にスコップ、押し込み棒等を使い詰め込み、タンパーやプレートコンパクターで転圧して既存舗装面と一体化し、表面側が平滑面となるように施工する。 The mixed repair material is packed in a repair area that has been cleaned in advance using a scoop, push-in bar, etc., and rolled with a tamper or plate compactor to be integrated with the existing pavement surface, so that the surface side becomes a smooth surface. .
転圧後、当該箇所に水を散布して冷却する。
硬化性に優れているので、施工後直ちに交通開放しても当該箇所より車のタイヤ等に補修用材料が付着することはない。
After rolling, cool the area by spraying water.
Since it is excellent in curability, even if the traffic is opened immediately after construction, the repair material does not adhere to the tires of the car from the location.
補修箇所が細くて深い場合には、当該箇所へ実施例１の舗装用骨材と舗装部材との混合物よりなる補修用材料を最底部まで詰めて補修することは困難なことが多い。そこで本実施例２は、そのような舗装面の欠損部分の補修工法の実施例である。 When the repaired part is thin and deep, it is often difficult to repair the part by filling the part with the repairing material made of the mixture of the aggregate for paving and the paving member of Example 1 to the bottom. Therefore, the second embodiment is an embodiment of a repair method for such a defective portion of the pavement surface.
まず、上記実施例１と同様の材料を分別して袋詰めしたものを補修を必要とする場所へ運搬する。
同時に、石油アスファルトと有機溶剤との混合溶液を満たした先端に細い吐出口を有する注入容器を用意する。
First, the same material as in Example 1 above is separated and packed into a bag that needs repair.
At the same time, an injection container having a thin discharge port at the tip filled with a mixed solution of petroleum asphalt and an organic solvent is prepared.
補修箇所が、舗装の初期に生じる細いひび割れ（ヘアークラック）や細くて深い亀裂部分、マンホール・排水桝・各種道路標識や照明手段の支持盤・中央分離設置物等の道路設置物と舗装部分との境界に生じている隙間或いは各種試験の試供体抜き取り箇所等の細くて深い欠損部分の場合は、まず、当該部分に上記石油アスファルトと有機溶剤とからなる混合溶液を注入容器の細い吐出口を利用して注入する。 Repair points include road cracks and pavements such as thin cracks (hair cracks) and narrow and deep cracks that occur in the early stages of pavement, manholes, drainage basins, various road signs and lighting means support boards, central separation installations, etc. In the case of a narrow and deep defect such as a gap generated at the boundary of the test sample or a sample sampling point for various tests, first, a mixed solution composed of the above-mentioned petroleum asphalt and an organic solvent is put in the relevant part with a thin discharge port of the injection container. Inject using.
上記混合溶液としては、有機溶剤に対して３０〜６０重量％の石油アスファルトを混合したものが良好である。該注入された混合溶液は流動性に優れているので、表面のひび割れや細くて深い欠損部分の最底位置まで到達し、充満する。それにより該欠損部分の周囲の壁に一部の混合溶液が滲み込むことになる。 As said mixed solution, what mixed 30-60 weight% petroleum asphalt with respect to the organic solvent is favorable. Since the injected mixed solution is excellent in fluidity, it reaches the bottom position of the cracks on the surface and the thin and deep defect portion and is filled. Thereby, a part of the mixed solution permeates into the wall around the defect portion.
その後、直ちに該欠損部分の表面側より小径寸法を袋詰めした舗装用骨材を対象として上記舗装部材と加熱混合した補修用材料を詰め込む。
該補修用材料は、様々な形状や折曲した比較的深い欠損部分の最底部まで全てが到達することは不可能である。しかし、棒状の細長いもの等によりある程度の位置まで押し込むことは可能である。その後、転圧して既存面と一体化し、表面に平滑面を形成する。
Immediately thereafter, the repair material mixed with the pavement member by heating is packed into the aggregate for pavement packed in a small diameter from the surface side of the defect portion.
The repair material cannot reach all the bottom of various shapes and bent relatively deep defects. However, it can be pushed to a certain position with a rod-like elongated object. Then, it rolls and integrates with the existing surface, and forms a smooth surface on the surface.
上記欠損部分に注入した混合溶液は、その舗装表面側が該補修用材料により塞がれることになり、密封空間内に留まり或いは乾燥アスファルト等の周壁に滲み込むことになる。同時に、該混合溶液は時間経過とともに蒸発現象を起こすため、該欠損部分に押し込まれた補修用材料の最先端部分に滲み込み、当該部分を軟化状態とする。上記軟化により既存部分との接着がより強化されることになる。 The mixed solution injected into the defect portion will be clogged with the repair material on the pavement surface side, and will remain in the sealed space or permeate into a peripheral wall such as dry asphalt. At the same time, since the mixed solution causes an evaporation phenomenon with time, the mixed solution soaks into the most advanced portion of the repair material pushed into the defective portion, and softens the portion. The softening will further strengthen the adhesion with the existing part.
上記実施例２により、舗装面の初期の細いひび割れ（ヘアークラック）或いはその後の亀裂並びに舗装部分と道路設置物との境界に生じる細い又は小さな欠損部分に該混合溶液を注入できるため、該欠損部分の壁面に滲み込み、老化したアスファルトとなじみ、該アスファルト分を活性化することができる。蒸発が終了した後にも上記により粘性のあるアスファルトが残留するため、舗装体の振動や移動に対して追従することが可能となった。 According to the second embodiment, the mixed solution can be injected into an initial thin crack (hair crack) on the pavement surface or a subsequent crack and a thin or small defect portion generated at the boundary between the pavement portion and the road installation. Can penetrate into the wall surface of the water and blend with the aged asphalt to activate the asphalt. Since viscous asphalt remains as described above even after the evaporation is completed, it becomes possible to follow the vibration and movement of the pavement.
また、補修用材料は上記の通り最先端部分が軟化されるため、既存のアスファルトとなじみ一体化される。同時に、該補修用材料自体の硬化による亀裂を抑制し、ブリッジ現象を防止することができる。
その結果、表面水の滲み込みや路床、路壁からの毛細管現象で上昇してくる水を遮断することができ、補修部分の補修効果を持続させることができる。
In addition, the repair material is softened at the leading edge as described above, so that it is integrated with the existing asphalt. At the same time, it is possible to suppress cracks due to hardening of the repair material itself and to prevent a bridge phenomenon.
As a result, it is possible to block water that rises due to the surface water soaking, the roadbed, and the capillary action from the road wall, and the repair effect of the repaired portion can be maintained.
