冰冻作用（隆起和融化）是土木工程结构的设计、施工和管理中遇到的一个长期问题，特别是在寒冷地区和经历季节性低于冰点温度的地区的道路路面。本文回顾了现有的方法来缓解冻胀，并提出了一种创新的方法，通过工程防水。从夏洛特道格拉斯国际机场的试验田收集土壤，并用市售有机硅烷处理。初步结果表明，处理后最大干密度从17.54 kN/m3增加到17.66 kN/m3，最佳含水率从17.36%降低到11.75%。从性能测试中获得的数据进行了亚冻结的天气条件下表明，处理是有效的限制渗透和迁移到土壤基质中的水相比，未经处理的土壤。因此，工程防水性可能是机场和交通部寻求减轻霜冻作用方法的可行解决方案。
Frost action (heaving and thawing) is a perennial problem encountered in the design, construction, and management of civil engineering structures, particularly road pavements in cold regions and areas that experience seasonal sub-freezing temperatures. This paper reviews the existing methods for frost heave mitigation and proposes an innovative approach through engineered water repellency. Soil was collected from a test plot at the Charlotte Douglas International Airport and treated with a commercially available organosilane. Preliminary results indicate an increase in the maximum dry density from 17.54 kN/m3to 17.66 kN/m3and a decrease in the optimum moisture content from 17.36% to 11.75% after treatment. Data obtained from performance tests carried out under sub-freezing weather conditions indicated that the treatment was effective in limiting the infiltration and migration of water into the soil matrix when compared with the untreated soil. As such, engineered water repellency may be a viable solution for airports and Departments of Transportation seeking methods to mitigate frost action.
