LOW-TEMPERATURE CONSTRUCTION TYPE ROAD REPAIR MATERIAL
To provide a low-temperature construction type road repair material which has high workability not only under normal temperature environment but also under low-temperature environment such as in cold district, and also can shorten the time from construction to full strength development.SOLUTION: A low-temperature construction type road repair material contains an aggregate, asphalt, dehydrated castor oil fatty acid, and an alkaline additive. Further, the freezing point of dehydrated castor oil fatty acid is preferably less than 0°C. Further, the weight ratio of asphalt and dehydrated castor oil fatty acid with respect to the aggregate is preferably in the range of 100:5 to 100:10.SELECTED DRAWING: Figure 1
【課題】常温環境下のみならず、寒冷地等の低温環境下においても高い施工性を有するとともに、施工してから十分な強度を発現するまでの時間を短縮化することができる低温施工型道路補修材を提供する。【解決手段】低温施工型道路補修材は、骨材と、アスファルトと、脱水ヒマシ油脂肪酸と、アルカリ性添加材とを含有する。また、脱水ヒマシ油脂肪酸の凝固点は０℃未満であることが好ましい。さらに、骨材に対する、アスファルトおよび脱水ヒマシ油脂肪酸の重量比は、１００：５〜１００：１０の範囲内であることが好ましい。【選択図】図１
