温拌再生沥青混凝土工作性研究

再生沥青混凝土在旧料用量较高时,常出现拌合困难的现象,因此探讨温拌添加剂应用于再生沥青混凝土有其重要性。针对温拌再生沥青混凝土,在较高路面旧料添加量与较低试件压实温度时,评估其工作性表现,以了解温拌添加剂对于再生沥青混凝土施工作业的影响。搜集国内外温拌沥青混凝土与再生沥青混凝土相关文献,以旧料添加量与试件压实温度为变量,采用车辙试验的车辙试件滚压设备,模拟现场沥青混凝土压路机的滚压过程,评估温拌再生沥青混凝土的工作性,可为国内推动温拌再生沥青混凝土的使用提供参考。

Mix the Recycled Asphalt Concrete Temperature Mix of Regeneration Asphalt Concrete Workability Research Study

Recycled asphalt concrete at a higher dosage of the old material, often mixing difficult and, therefore, explore the warm mix additives used in recycled asphalt concrete has its importance. In this study, renewable for warm mix asphalt concrete pavement of the old material at high volume and low added specimen compaction temperature, to assess the performance of their work, in order to understand warm mix additives for recycled asphalt concrete construction jobs impact. This study collected abroad warm mix asphalt concrete and recycled asphalt concrete literature, adding to the amount of old material specimen compaction temperature as a variable, using rut rutting test specimen roiling equipment to simu- late the roiling process asphalt compactor scene assess the work of regeneration warm mix asphalt con- crete, can provide reference for domestic use to promote the regeneration of warm mix asphalt concrete.
