| 摘 要： | 以陕西省某高速公路扩建工程为依托,对路基黄土填料掺加石灰进行改良,并开展室内常规土工试验,研究了改良黄土的路用性能。结果表明:①石灰土比黄土的最佳含水量大;②石灰土CBR值较黄土的CBR值提高了14.9倍;③石灰土浸水后的CBR值较浸水前的CBR值有所提高;④石灰土的膨胀量明显减小,水稳定性有较大的提高。

Experimental Study on the Pavement Performance of Lime-loess |
| |
| Abstract: | The loess filler must be improved by mixing lime for the subgrade based on a highway extension project of Shanxi, and routine laboratory soil test is made to research the pavement performance of the lime-loess. The results show that ①the lime soil has greater optimum moisture content than the loess; ②the CBR value of the lime soil is 14.9 times CBR value of the loess; ③compared with before flooding, the CBR of the lime soil is increased after flooding; and ④the swelling capacity of the lime soil is significantly reduced, and water stability has greatly improved. |
