This project is in accordance with AD/ENG Bulletin 85-25 for Innovative and Novel Research. The problem of ice formation on highways and bridges is a constant cause of accidents and fatalities in northern climates, in addition to the cost of providing materials to reduce the hazard. Salts, sand and ashes of various types have been used to reduce the icing effect, but these precautions do not eliminate the cause of icing. This project will explore fundamental studies on the formation of ice to pavement bond and to explore methods by which the bond formation may be prevented. The study will involve the correlation of chemical and mechanical behavior to determine the mechanism o> ice formation and investigate methods of deicing to eliminate the action. The effect of surface agents and hydrophobic coatings will be investigated. The researcher is qualified to perform this investigation. This is a one time award for 12 months.

该项目符合 AD/ENG 公告 85-25 的创新和新颖研究。 除了提供减少危险的材料的成本外，高速公路和桥梁上的结冰问题也是北方气候下事故和死亡的一个常见原因。 各种类型的盐、沙子和灰烬已被用来减少结冰效应，但这些预防措施并不能消除结冰的原因。 该项目将探索冰与路面粘结形成的基础研究，并探索防止粘结形成的方法。 该研究将涉及化学和机械行为的相关性，以确定冰形成的机制，并研究消除冰作用的除冰方法。 将研究表面剂和疏水涂层的效果。 研究人员有资格进行这项调查。 该奖项为一次性奖项，为期 12 个月。
