文章认为,改性沥青混合料设计应针对沥青路面中可能出现的主要病害,如车辙或开裂,以采取相应的对策。笔者就几年来的试验和研究,对改性沥青混合料设计中沥青基料、外掺剂的选择、集料级配、外掺剂剂量以及改性结合料用量的确定,提出了具体的方法和图表。同时指出,为确保所设计混合料性能的可靠性,必须进行有关试验验证。此外,还就改性沥青路面结构提出了建议。
The article holds that the design of modified asphalt mixture should be aimed at the main diseases that may occur in the asphalt pavement, such as rutting or cracking, so as to take corresponding measures. The author of the past few years of experiments and studies, the design of modified asphalt mixture asphalt binder, the choice of external admixture, aggregate gradation, dosage of external admixture and the amount of modified binder to determine the specific method And chart. Also pointed out that in order to ensure the reliability of the performance of the design of the mixture, the relevant test verification must be carried out. In addition, the proposed modified asphalt pavement structure.
