摘要
文章对不同年份赤泥基层材料的性能进行了对比分析,试验结果表明,1年、3年、10年赤泥混合料7天抗压强度均可达2.9 MPa以上,28天抗压强度达到3 MPa以上,远远超过路基标准;三种混合料的回弹模量基本相同,保持在580 MPa左右;抗冻性方面,3年和10年混合料要优于1年混合料;运用液塑限联合测定法测定液塑限,发现其值有随年份递减的趋势。
In the paper, we made a comparison of the property of red mud in different ages. The results of the experiences show that the compressive strength of seven days and twenty-eight days are all over 2.9 MPa or 3 MPa, which is far beyond the standard of the road base; The EO value of soil base resilience modulus of the three are all around 580 MPa. For the frost resistance, the base material of 3 ages and l0 ages are better than the 1 age. We also texted the pile structure integrity of the materials, and the result showed that its value reduced with its storing time.
