摘　　要：为了解季冻区的掺灰土在经过冻融循环作用后的强度变化规律,选取试验路段具有代表性的土样,在室内将原路基土与掺灰土经不同冻融循环次数下的CBR试验结果进行对比分析,试验结果表明:掺灰可以明显提高季冻区路基土经冻融循环作用后的CBR值。To understand mixed dust in high latitude area after freeze-thaw cycle effect the strength of the change law of selecting representative soil samples test section, the inside will contains the original roadbed soil and lime soil under different freezing and thawing cycles under the CBR, comparing the test results show that mixed ash can obviously increase the subgrade CBR value of the soil after freezing and thawing cycle effect.

关 键 词：路基 掺灰土 冻融循环作用 CBR值
