融雪材料对沥青混凝土性能的影响研究

摘要

From the point of view of engineering application of salinized soil at coastal area, experimental study is performed for improvement with cement. On the basis of understanding the mechanism of improving strength of salinized soil with cement, the changing rules of shearing strength, compression strength, water sensitivity, thaw collapsibility and expansibility of salinized soil at coastal area along with dosage and age of modifier are analyzed. The result shows that: the shearing strength, compression strength and water sensitivity of improved salinized soil with cement has improved obviously. Thaw collapse and expansion is controlled effectively. The soil could be used for filling of subgrade of high class highway.%通过对使用融雪材料环境条件下,沥青混合料SMA-13L的马歇尔稳定度、水稳定性、低温性能、路面抗滑性能的研究测试,探讨了不同融雪材料对沥青混凝土路用性能的影响,为冬季公路融雪除冰提供参考。
