| 摘 要： | 以贵阳-清镇高速公路为依托工程,采用室内承载板法分析了红粘土压实度、含水率、稠度、龄期与回弹模量的关系,以及最不利条件下,回弹模量与压实度的关系.采用路面材料强度仪进行了未泡水的CBR试验、泡水24、48 h和96 h的CBR试验.结果表明,红粘土回弹模量与含水率关系可以用幂函数拟合;回弹模量与压实度和稠度指标具有良好...

| Abstract: | Based on Guiyang-Qingzhen Expressway construction project,using indoor loading plate,the relations of resilent modulus with physical indexes of red clay such as compaction degree,water content,consistency and age were analyzed.The relation between resilent modulus and compaction degree under the worst unfavourable condition was also tested.Using pave material strength instrument,a serials of CBR tests under the conditions of unimmersion,immersed for 24 h,48 h and 96 h were performed.The results show that(1)... |
