する床版の防水施工方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor slab waterproofing method in which a synthetic resin waterproof layer is formed on a floor slab of a road bridge or the like, and asphalt pavement is formed thereon.

の維持管理はとりわけ重要である。2. Description of the Related Art In road bridges for general roads and highways, asphalt paved road surfaces are often formed on steel or concrete floor slabs. Damage to the asphalt road surface can be repaired relatively easily, but floor slabs are difficult to repair, so maintenance is especially important.

注目されてきている。Recently, although the damage of the floor slab has a large load-related factor, it has been clarified that it is often caused by the promotion of cracks caused by water and the reduction of load resistance due to the corrosion of reinforcing bars, and it has been particularly used conventionally. Since the asphalt-based waterproofing material has a difficulty in shielding salt water and chlorine ions, a synthetic resin waterproof layer is interposed to prevent rainwater from entering the floor slab from the asphalt road surface. The method is getting attention.

分な接着力を確保することは困難であった。However, the synthetic resin-based waterproof layer cannot secure sufficient adhesiveness with the asphalt layer applied on the waterproof layer as compared with the asphalt-based waterproof layer,
Due to this, cracks and potholes may be immediately formed on the road surface, and serious defects such as the asphalt layer being displaced from the floor slab may occur. In order to prevent the occurrence of such defects, methods such as spraying a non-slip aggregate or coating an asphalt emulsion on the waterproof layer have been generally performed. However, the non-slip aggregate alone is not sufficient to improve the adhesive strength.On the other hand, a method of increasing the adhesive strength between the resin waterproof layer and the asphalt emulsion layer by applying a large amount of asphalt emulsion and thickening the solidified film is Since it takes a long time to dry and solidify the asphalt emulsion, it is impossible due to the time constraints of the construction work, and the conventional method of applying a small amount is obliged to be carried out.As a result, sufficient adhesive strength is secured. It was difficult.

点接触の集合状態で接触しているため、両層間の接触面
積が小さいことによるものであることを解明した。As a result of diligent studies on the enhancement of the adhesive force between the resin waterproof layer and the asphalt layer, the present inventors have found that a substantial adhesive force should be exerted between the resin of the waterproof layer and the asphalt, but it is actually small. Only the adhesive force can be exhibited, because the asphalt layer is made quite porous by the aggregate and the resin waterproof layer and the asphalt layer are in contact with each other in a point contact state, so the contact area between both layers is small. It was clarified that it was due to a thing.

３．０ｍｍ程度の厚みで形成される。In the method of the present invention, first, a synthetic resin waterproof layer is formed on the floor slab. The synthetic resin waterproof layer can be formed in the same manner as a conventionally known method. That is, if the floor slab is damaged or fragile, it is repaired, and the surface is cleaned as necessary. Then, a primer is applied by a roller, a brush or the like to perform a base treatment. afterwards,
A synthetic resin waterproof layer is formed by uniformly applying a liquid synthetic resin on the floor slab to which the primer has been applied, using a rubber spatula or a flexible bow key. The synthetic resin waterproof layer is usually 0.5 to
It is formed with a thickness of about 3.0 mm.

発明の方法では防水シートは使用しない。Conventionally, a waterproof sheet is also used for the waterproof layer, but when a finisher or a dump truck passes over it during paving of an asphalt mixture, there is a risk of slippage or a waterproof defect at the joint. Therefore, the waterproof sheet is not used in the method of the present invention.

材を散布することが好ましい。In the method of the present invention, the non-slip aggregate can be sprayed before the synthetic resin waterproof layer is completely cured. As a result, the non-slip aggregate is fixed in a state where the aggregate particles are somewhat buried in the surface of the synthetic resin waterproof layer. This non-slip aggregate roughens the surface of the synthetic resin waterproof layer and forms a physical entanglement relationship with the asphalt layer formed on it, especially when shear stress acts between layers. It is preferable to sprinkle anti-skid aggregates to help counter this.

で好ましくない。The thermoplastic resin granules used in the present invention can be not only granules of general thermoplastic synthetic high molecular polymers and petroleum resins but also granule asphalt, and granule asphalt is particularly preferable. The thermoplastic resin particles preferably have a particle size of 5 mm or less, and have a particle size of 0.3 to 3 m.
It is particularly preferred to have a particle size of m. The thermoplastic resin granules preferably have a softening point of 60 to 130 ° C, and particularly preferably those having a softening point of 70 to 125 ° C. If the softening point is higher than 130 ° C., when the heated asphalt mixture is spread on the synthetic resin waterproof layer, the thermoplastic resin particles do not soften sufficiently, so the effect of spraying the thermoplastic resin particles is There is a possibility that the adhesive force between the layers cannot be exhibited and the adhesive force between the layers becomes insufficient.
Further, the thermoplastic resin particles having a softening point lower than 60 ° C.
It is not preferable because the particulate matter causes blocking and cannot be sprayed.

くない。The thermoplastic resin granules may be sprinkled in the powdery state of the thermoplastic resin granules, or may be sprinkled by moistening with an aqueous medium. As such an aqueous medium, in addition to water itself,
Examples thereof include an aqueous solution prepared by dissolving a water-soluble polymer in water, a synthetic polymer latex, a synthetic polymer latex containing an organic solvent such as toluene or xylene, and an asphalt emulsion. As an aqueous medium, after the water has finally evaporated, the thermoplastic resin particles are bound or bound together, and the adhesive strength between the synthetic resin waterproof layer and the paved asphalt mixture layer is minimized. It is preferably composed of a component that does not limit the effect or rather improves the adhesive strength. In particular, the particle size of the thermoplastic resin particles is 0.5 mm
When it contains a large amount of fine particles of less than, it is more effective to wet with an aqueous medium in order to prevent scattering by wind. However, if the amount of the aqueous medium used is too large, it takes time to dry, the temperature of the contact portion with the heated asphalt mixture may be lowered, and the softening of the thermoplastic resin particles may be insufficient and the adhesive strength may be reduced. It is not preferable.

働きもすることになる。The application of the thermoplastic resin particles can be carried out simultaneously with the application of the non-slip aggregate. In this case, some of the thermoplastic resin granules may be embedded in the surface of the synthetic resin waterproof layer to some extent, so that the thermoplastic resin granules also have the same function as the non-slip aggregate.

する。When the heated asphalt mixture heated to about 150 ° C. is spread on the synthetic resin waterproof layer, the thermoplastic resin granules in contact with the heated asphalt are softened and melted, and the synthetic resin waterproof layer and the heated layer are heated. The contact area with the asphalt can be increased and the adhesion between the waterproof layer and the asphalt layer can be increased. The leveled heated asphalt is usually immediately subjected to leveling and some compaction operations by a device such as a tamper or screed of an asphalt finisher, and then heated by a road roller, tire roller, vibrating roller, etc. Is finally compacted and the asphalt pavement is completed.

工事で実用的である。Further, unlike the conventional construction method using an asphalt emulsion, the time required for drying and solidifying the emulsion is unnecessary, and the asphalt pavement can be constructed immediately after the curing of the synthetic resin waterproof material is completed. This is extremely effective in making the most of the characteristics of synthetic resin waterproofing materials, which are generally considered to have a very short curing time, and construction of road bridges with restricted traffic control times in urban areas and highways, Especially practical for repair work.
