摘要：

首先采用干燥条件和浸水条件下的劈裂试验研究了水泥加料顺序对半柔性再生混合料性能的影响,在此基础上提出击实试验法与修正的马歇尔试验法相结合,并基于性能评价的混合料配合比设计程序,包括材料选择、级配设计及性能评价。研究结果表明：先添加水泥的半柔性再生混合料具有密实的整体结构,且抗水损坏能力较强;半柔性再生混合料具有良好的高温抗车辙能力、低温抗开裂能力、抗水损害能力以及抗收缩能力。结合依托工程发现,基于改性乳化沥青-水泥双胶结料的半柔性再生技术是一种经济有效的路面大中修养护方式,有着良好的经济效益、社会效益和环境效益,具有重要的推广应用价值。

Abstract:

Dry and immersion split tests with different cement sequences were carried out, in which performances of semi-flexible recycled mixtures might be affected. The properties of mixtures were based on the compaction test method, the Marshall test method and performance evaluation. A design procedure which included original material selection, gradation design and performance evaluation was proposed. The results first indicated that semi-flexible recycled mixtures with added cement had a denser structure and good moisture stability. Also, semi-flexible recycled mixtures had good high temperature stability, moisture stability, resistance drying shrinkage and temperature shrinkage. The actual project showed that semi-flexible recycled technology had an economic and environmental significance and the application deserved promotion.
