若在再生沥青混合料中掺加70%旧路面材料,则有助于环境保护和不可再生资源的重复利用,因此该做法受到了公路工程人员的亲睐并且他们对其展开了大量的研究。该文提出了采用显微图像技术来观察沥青混合料中新沥青结合料与再生料中沥青结合料的融合,并定量评价新旧结合料的融合程度,量化了生产参数如拌和温度、拌和时间对掺加的再生沥青结合料胶团与新沥青结合料融合过程的影响即对其消失历程的影响。
The incorporation of 70% of the old pavement materials into the recycled bituminous mixture contributes to environmental protection and the reuse of non-renewable resources, and is therefore favored by highway engineers and they are extensively studied. This paper presents the use of microscopic image technology to observe the asphalt mixture of new asphalt binder and renewable materials in the asphalt binder fusion, and quantitative evaluation of the old and new binder fusion degree, quantified the production parameters such as mixing temperature, mixing time on The effect of the blended regenerated bitumen binder micelles and the fusion process of new bitumen binders is the effect on the vanishing process.
