| 中文摘要: |
| 介绍了国内外就地冷再生技术的应用现状,通过PCI和SSI指标评价了旧路状况:研究了作为面层的乳化沥青就地冷再生混合料的配合比设计并进行了路用性能试验;确定了最佳乳化沥青用量和水泥用量:通过国外先进的就地冷再生机组的工程应用总结了施工工艺.研究表明就地冷再生是一种有效的沥青路面养护方式. |
| 英文摘要: |
| Application status of foreign and domestic cold in-place recycling (CIR) technique were introduced. The status of old asphalt pavement was evaluated based on PCI and SSI indexes. The mix design of CIR used as surface course was studied,and recycled mixture performance tests were also evaluated,moreover,optimal asphalt emulsion and cement content were determined. The construction techniques were summarized based on construction process with foreign advanced CIR devices. The results indicate that asphalt emul... |
