冷补沥青混合料具有不受天气条件限制、随用随补等优点,但是由于缺乏冷补沥青混合料路用性能关键评价指标体系、优化的配合比设计和相应的试验方法,造成其质量良莠不齐,不能充分发挥冷补沥青混合料的优势。针对这一系列问题,笔者针对安徽省公路现状和气候特征,自主开发了AH型冷补沥青混合料,进行现场铺筑、跟踪、检测,提出了AH型冷补沥青混合料的适用范围、关键评价指标以及AH型冷补沥青混合料的强度稳定时间。
Cold-asphalt mixture with weather conditions, with the use of such as with the advantages, but due to the lack of cold-fill asphalt road performance key evaluation index system, the optimization of the mix design and the corresponding test methods, resulting in its quality varies greatly , Can not give full play to the advantages of cold-fill asphalt mixture. In response to this series of questions, the author independently developed AH-type cold-fill asphalt mixture for the road conditions and climatic characteristics in Anhui Province, paving, tracking and testing on site, and put forward the applicable scope of AH type cold-fill asphalt mixture, the key Evaluation index and strength stabilization time of AH type cold-fill asphalt mixture.
