い方をされている。2. Description of the Related Art In recent years, pavement having drainage and / or water permeability has been rapidly increasing in performance due to securing of driver's safety in rainy weather and consideration of residents along the water pool. On the other hand, the demand for drainage or / and permeable pavements using a color mixture has been increasing year by year in order to improve the townscape. Asphalt used for these pavements is often added with a polymer material such as rubber or resin in order to increase durability and weather resistance,
When pavement is performed on a road surface, the vehicle is usually transported by truck to a work site, deployed on the road surface, and compacted smoothly by a compaction work roller such as a road roller or a tire roller.

スファルトに対しては、離型効果がかなり低いという問
題があった。[0003] Asphalt during transportation and construction is kept at a high temperature in order to reduce viscosity and increase fluidity, but asphalt with increased fluidity is used as a carrier for trucks and rollers for compaction work. There is a problem in that it easily adheres, and if it adheres, various workability is reduced. Therefore, conventionally, in order to prevent such asphalt from adhering, a petroleum-based solvent or a vegetable oil composed of, for example, crude oil evaporation has generally been used as a release agent (release agent). However, the effect of these release agents is not sufficient, and there has been a problem that the releasing effect is considerably low, particularly for various drainage or / and water-permeable asphalts which have been frequently used in recent years.

Because water passes through that space, it has excellent drainage and water permeability,
This has the effect of preventing puddles on the road surface and, at the same time, preventing slip (prevention of the hydrobrane phenomenon). Further, an appropriate gap has an effect of preventing noise due to friction between a road surface and a tire.

付着し易くなるという問題があったのである。[0005] Since the drainage (permeable) asphalt has more voids than conventional asphalt, the asphalt is point-bonded. Therefore, it is necessary to increase the adhesion (adhesion), and a polymer material such as rubber or resin is added. However, if this is done, the viscosity and adhesion (adhesion) will increase, so the truck bed and compaction There is a problem that the toner easily adheres to a roller for use.

ような問題の生じない付着防止剤の開発が強く望まれて
いたのである。Conventionally, an anti-adhesion agent has been used to prevent the adhesion. However, the conventional anti-adhesion agent uses a large amount of an organic solvent such as a petroleum-based solvent in order to enhance the anti-adhesion effect on asphalt. Since it was used, discoloration and deterioration of the pavement surface were apt to occur, and there was a concern about environmental problems due to organic solvents. In particular, in the case of color asphalt, unlike black asphalt, when the discoloration or the quality is changed, the finish feeling is remarkably deteriorated. Therefore, it has been strongly desired to develop an anti-adhesion agent which does not cause such a problem.

In the case of color asphalt, deterioration of the finish due to discoloration or deterioration has also been a problem. When diluting an emulsion, dilution stability becomes a problem,
In addition, when used at a high concentration, there are problems such as clogging of a spray pipe such as a roller.

Provided an anti-adhesion agent for oil or silicone emulsion (emulsion). Water-insoluble silicone oil diluted with these organic solvents and water-insoluble silicone oil that appears when emulsion is broken at high temperature Has excellent compatibility with organic solvents and organic resins at the same time, and especially in the case of drainage or / and water-permeable asphalt to which a large amount of resin is added, it is soluble in those resins. There was a problem that it adhered together with asphalt. In particular, the problem has been a serious problem in the case of color asphalt.

It solves the above-mentioned problems of the water-insoluble or emulsified anti-adhesion agent which has been used for drainage or / and water-permeable asphalt for pavement, and has an excellent releasing effect on asphalt, particularly color asphalt.

It is presumed that there is no change in the physical properties in the region, and even at the use temperature of about 150 ° C. during paving, the compatibility with asphalt can be maintained because of the uniform system. In general, when an anti-adhesion agent is used on site, it is preferable to adjust the viscosity in consideration of the workability. That is, since the work is difficult if the viscosity is high, it is preferable to appropriately dilute the silicone solution of the present invention with water and adjust the viscosity of the adhesive to 500 cs or less.
