通过对掺加聚酯纤维沥青混合料进行室内试验和施工工艺关键环节研究,分析了特殊路段中面层AC-20型沥青混合料的级配优化、油石比选定、路用性能的影响及施工工艺控制。结果表明:特殊路段中掺加聚酯纤维沥青混合料的级配应偏细些,最佳油石比宜在普通路段沥青混合料基础上增加0.2%,且具有良好的路用性能,并提出了施工工艺中关键环节的控制要点,可供特殊路段施工参考。
Based on the laboratory test and key research on the construction process, the gradation optimization, the ratio of stone to stone and the road performance of AC-20 asphalt mixture in the special section are analyzed. Construction process control. The results show that the gradation of asphalt mixture mixed with polyester fiber in special sections should be slightly thinner, and the optimal ratio of asphalt to asphalt should be increased by 0.2% on the basis of common asphalt mixture, and has good road performance. The key points of the construction process control points for the construction of a special section of reference.
