The use of roadway deicers, typically made of sand or salt, is essential for achieving safe roadway conditions by reducing ice and snow. Unfortunately, deicers can have detrimental effects on the surrounding infrastructure and environment. Traditional inorganic deicers, such as abrasives and chloride salts, have the most widespread usage, but recent concerns of the negative effects of chlorides on the environment have led to emerging alternative organic deicers. This paper provides a comprehensive review of the effectiveness and impacts of organic deicers including agro-based products, acetates, formates, glycols, and succinates. The benefits and negative impacts on the road, environment, and infrastructure are reviewed, as well as the performance of each deicer for snow and ice control on roadways. The environmental concerns of the organic deicers are discussed, including the largest environmental concern: the increase in biological oxygen demand (BOD) to receiving water bodies. The impact of deicers on metals and infrastructure is presented as it varies considerably for each alternative deicer. Finally, opportunities and challenges to implementing alternative deicers in the field is discussed.

冬季道路养护的替代除冰剂—综述

使用通常由沙子或盐制成的道路除冰剂,对于通过减少冰和雪实现安全的道路状况至关重要。不幸的是,除冰剂会对周围的基础设施和环境造成不利影响。传统的无机除冰剂,例如磨料和氯化物盐,使用最广泛,但是最近对氯化物对环境的负面影响的担忧导致出现了替代性有机除冰剂。本文对有机除冰剂的有效性和影响进行了全面的综述,包括农业基产品,乙酸盐,甲酸酯,乙二醇和琥珀酸酯。审查了对道路,环境和基础设施的好处和负面影响,以及每种除冰剂在道路上除冰和除冰的性能。讨论了有机除冰器的环境问题,包括最大的环境问题:接收水体对生物需氧量(BOD)的增加。介绍了除冰剂对金属和基础设施的影响,因为每种替代除冰剂的影响差异很大。最后,讨论了在野外实施替代除冰剂的机遇和挑战。
