第４表
以上説明した本発明によると以下に示すような効果があ
る。According to the present invention described above in Table 4, there are the following effects.
１、骨材を加熱し、しかもアスファルト等を加熱混合す
るために、製品の含水比はＯ〜２チ程度であシ、油分に
よる疎水効果は半永久的となる。1. Because the aggregate is heated and asphalt etc. are heated and mixed, the water content of the product is approximately 0 to 2 degrees, and the hydrophobic effect of the oil is semi-permanent.
２、骨材の粒度は、その骨材配合によシ全く任意に変更
できるために、在来上と混合する場合最も望ましい粒度
とすることができる。また、在来上を本願疎水化上と混
合することにより所望の粒度の±に変更することもでき
るものである。2. Since the particle size of the aggregate can be changed completely arbitrarily depending on the aggregate composition, it can be set to the most desirable particle size when mixed with conventional aggregates. Furthermore, by mixing the conventional surface with the hydrophobized surface of the present invention, the particle size can be changed to a desired particle size.
３、本願疎水化上は一般の土とほぼ同じ色および粒度で
あるために自然環境に融和し不自然さがない利点を有す
る。3. Since the hydrophobization of the present invention has almost the same color and particle size as ordinary soil, it has the advantage of being compatible with the natural environment and not looking unnatural.

Aggregate A consisting of any one of screening sand, coarse sand, fine sand, and silica sand, or a mixture of these in any proportion, should be 40 to 100% of the total weight; Aggregate B, which is one of fine limestone powder, calcium hydroxide, bentonite, silica clay, and diatomaceous earth, or a mixture of these in any proportion, is added at a ratio of 0 to 60% of the total weight, and asphalt, heavy oil. A hydrophobizing agent characterized by comprising any one of paraffin, waste oil, petroleum resin, etc., or a mixture of these in any proportion. 2. Aggregate A, which is any one of screenings, coarse sand, fine sand, and silica sand, or a mixture of these in any proportion, is heated to 120 to 300°C with a dryer at 40 to 100 grams of the total weight. Then, aggregate B containing any one of limestone fine powder, calcium hydroxide, bentonite, silica clay, and diatomaceous earth or a mixture of these in any proportion is added to the above aggregate A with a total weight of 0 to 60 g. Added to make mixed aggregate, which is then mixed with asphalt, heavy oil, paraffin, and waste oil. 1. A method for producing hydrophobization, which comprises producing by mixing any one type of petroleum resin or an additive material obtained by mixing these in any ratio at 120 to 180° C. with the above-mentioned mixed aggregate.
