| 摘 要： | 为了深入分析冷再生混合料的级配问题,用美国伊州贝雷法进行冷再生混合料级配设计优化研究,并采用乳化沥青和水泥两种添加剂来改善冷再生混合料性能.通过分析比较旧沥青混合料和经过沥青抽提试验后的旧混合料的筛分结果来确定原始旧混合料用作骨料的级配,再分别选用旧沥青混合料原样筛分和抽提筛分曲线来添加一定比例的新骨料和水泥来配置冷再...

| Abstract: | In order to deeply analyze the gradation of cold recycled mixture,the optimization of cold recycled mixture gradation was carried out by using Bailey method,both emulsified asphalt and cement were utilized as additives to improve the properties of cold recycled mixture.Then,the screening of RAP material and that of aggregate in RAP material were compared to determine the gradation of RAP material,certain percentages of new aggregate and cement were added to form the skeleton of cold recycled mixture by usin... |
