本文通过室内击实试验研究了风积砂的最佳含水量和最大干密度；且通过静载荷试验，对风积砂的压实特性进行了研究。

When rolling the roadbed, the best degree of compaction is 93%~95%. When taking Aeolian sand for preventing the water rising, the Aeolian sand replacement should be set above water table, which should normally be made at 50~80 cm depth of soil base with 15~20 cm thickness of replacement for medium wet subgrade and 20~30 cm for wet subgrade. When using stabilized soil inorganic binder for prevention and control of the frost damage, the thickness of the binder is about 25 cm The mass proportion of cement, coal and Aeolian is about 6:40:54 and lime, fly ash and aeolian is about 14:30:56. Based on these, comparative evaluation for various preventing and curing measures of the Aeolian subgrade was given.

通过对试验数据分析得到了其冻结规律，采用碾压击实法，其最佳压实度度为93%~95%；采用风积砂换填隔水法，风积砂垫层时位置应在地下水位以上，一般应在土基50~80 cm深度处铺筑，换填厚度在中湿路基为15~20 cm，潮湿路基为20~30 cm；采用无机结合料稳定土防止、防治风积土路基道路冻害，厚度均应在25 cm左右，其中水泥、煤渣、风积土的质量比约为6：40：54，石灰、粉煤灰、土三者的质量比为14：30：56，在此基础上，对各种措施的防治效果进行了对比评价。

Against these frost damages, took the measures which were presented against the basic causes for the prevention and curing of the frost damage, for instance, rolling the roadbed, replacing the Aeolian sand and stabilizing the soil of inorganic binder and so on, and did experimental study indoor for every preventing and curing measure. The rule of frost damage has been concluded based on the analysis of experimental data.

针对这些冻害，从其产生的根本原因出发，采取碾压击实路基、风积砂换填、无机结合料稳定土路基等措施对其进行防治，并进行了路基风积土冻结试验、碾压击实试验、风积砂换填试验、水泥煤渣稳定土层和石灰粉煤灰稳定土层试验研究。
