摘要
主要简述中国沥青路面维修和翻新过程中的问题,乳化沥青混合料冷再生技术的技术机理、优缺点和道路工程中的应用范围。并且通过例举了不同地区、不同层位的道路工程中厂拌冷再生的应用,对乳化沥青混合料的最佳级配,乳化沥青混合料低温性能、沥青拌合厂施工工艺及现场拌和混合料施工指南都提出了合理的建议。说明厂拌冷再生技术在道路工程中有越来越广泛的应用。
The problems in the process of repair and renovation of asphalt pavement in China,the technical mechanism,advantages and disadvantages of cold recycled technology of emulsified asphalt mixture and the application range in road engineering were described.By exemplifying the application of cold mixing regeneration in road works in different regions and different levels,the optimal grading of emulsified asphalt mixture,the low temperature performance of emulsified asphalt mixture,the construction technology of asphalt mixing plant and the on-site mixing and mixing material construction guidelines made reasonable recommendations.It was showed that the plant mixed cold regeneration technology had more and more applications in road engineering.
