摘要：提出了一种确定土壤霜冻敏感性的新冻结试验，以取代目前由工程兵部队指定的标准 CRREL 冻结试验。该测试将确定土壤霜冻敏感性所需的时间减少了一半。它还可以确定冻胀和融化弱化敏感性，并考虑冻融循环的影响。新的冷冻测试通过完全自动化温度控制和数据观察，消除了人为因素引起的测试结果的大部分变化。关键词：机场；易受霜冻影响的土壤；路面设计；道路。
Abstract : A new freezing test for determining the frost susceptibility of soils is presented to supplant the standard CRREL freezing test currently specified by the Corps of Engineers. This test reduces the time required to determine the frost susceptibility of a soil in half. It also allows for the determination of both the frost heave and thaw weakening susceptibilities and considers the effects of freeze-thaw cycling. The new freezing test eliminates much of the variability in test results caused by the human element by completely automating the temperature control and data observations.
