を行っている。<Prior art> Conventional work shoes for asphalt pavement construction have a structure in which a heat insulating material is inserted between the insole and the rubber sole so that the high heat of the asphalt surface during asphalt construction cannot be transmitted to the inside of the shoe. Since the construction is carried out while walking on a flexible asphalt surface, a shoe with a smooth bottom structure is used. This asphalt paving work
High temperature asphalt is spread on the road, and workers walk on the asphalt surface while working, but immediately after spreading the asphalt, the asphalt itself is quite hot and flexible, and over time We are working under the condition that the temperature of the product decreases and becomes hard.

を進める上で大変不便になるという問題があった。<Problems to be solved by the invention> In conventional asphalt work, when walking on a fairly hot asphalt surface, heat insulating shoes are worn to prevent the heat from being transferred to the inside of the shoe. There is no problem with heat at the time, but there is a problem in that high temperature asphalt is characterized by being flexible and easy to bond. Asphalt, which is flexible and easy to adhere, is often adhered to the bottom surface of work shoes because the worker walks on the surface during work. And as it cools as it is, after work, the asphalt attached to the bottom of the shoe remains as a lump, reducing the resistance of the asphalt work shoe, and at the next work, asphalt in a new high temperature state attaches to the attached asphalt, There is a problem that it becomes easy to adhere and it is very inconvenient for the work to proceed.
従って、高温状態のアスファルト面歩行に際しても靴底
面にアスファルトの付着、接着しない作業靴が望まれて
いた。Therefore, there is a demand for work shoes in which the asphalt does not adhere or adhere to the bottom surface of the shoe even when walking on a high temperature asphalt surface.
〈課題を解決するための手段〉 本考案は、上記課題を解決し、高温で柔軟な状態のアス
ファルト面上を歩行してもアスファルトが靴底に付着、
接着することなく、かつアスファルトの高温を靴内部に

ト舗装靴を提供するものである。<Means for Solving the Problems> The present invention solves the above problems, and the asphalt adheres to the sole even when walking on the asphalt surface in a high temperature and flexible state,
(EN) An asphalt paving shoe used for asphalt construction without adhering and not transmitting the high temperature of asphalt to the inside of the shoe.
即ち、本考案は、離型剤を含むゴム粒子１をゴム材２中

てなるアスファルト舗装靴である。That is, according to the present invention, a heat insulating material layer 4 is provided between a rubber sole 3 and a midsole 5 in which rubber particles 1 containing a release agent are dispersed in a rubber material 2, and a rubber sole 3 is provided at the periphery of the shoe sole. An asphalt pavement shoe in which the upper 6 is directly joined.

なるのである。<Operation> When the asphalt construction is carried out by wearing the asphalt pavement shoes of the present invention, the weight of the worker and the weight of the work tool of the worker are applied to the sole of the shoe, and as a result, the rubber material 2 of the rubber sole 3 is The release agent in the rubber particles 1 dispersed in the toner gradually exudes to the surface of the rubber bottom 3 by pressing, and a release layer is formed on the surface of the rubber bottom 3. The release layer formed on the rubber bottom 3 surface prevents the asphalt in a high temperature state from adhering to the rubber bottom 3 surface, and after cooling, that is, after the work is finished, the shoe bottom surface maintains the state before use. is there.

有するものとなる。<Example> The rubber bottom 3 is a rubber material 2 kneaded with an ordinary rubber bottom material.
And the rubber particles 1 are used. As the rubber particles, the same material as the rubber material 2 is once vulcanized, and the vulcanized rubber is pulverized into particles. The vulcanized rubber particles are mixed with an oil-based releasing agent such as silicone oil, polyethylene wax, or fatty acid amide to obtain a state in which the releasing agent is enclosed in the rubber particles. The rubber bottom 3 is constituted by the rubber thus created. A heat insulating material layer made of an appropriate material is provided between the rubber sole 3 and the midsole 5, and the upper 6 of the shoe upper and the rubber sole 3 are pressure-bonded to each other at the periphery of the shoe sole to form a shoe. At this time, the rubber particles 1 encapsulating the release agent are not exposed on the surface of the periphery of the shoe sole,
Since the rubber for the rubber bottom in the state of unvulcanized rubber and the upper are in direct contact, by pressing and vulcanizing in this state,
At the peripheral portion of the shoe sole, the rubber sole 3 and the upper 6 are firmly joined. The thus-obtained asphalt pavement shoe has a rubber bottom in which rubber particles 1 containing a release agent are dispersed in the rubber bottom 3 firmly bonded to the upper at the peripheral edge of the shoe bottom.
