应用层次分析法,结合沥青路面的主要路用性能,确定了沥青路面的改性因素层次结构图。以SBS、PE和EVA等3种材料作为沥青路面改性材料性能的研究对象,建立了适用性分析模型,旨在通过此模型构造判断矩阵求解出特征向量,最后根据排序结果,从改性沥青的路面性能改善情况确定3种材料的适用性,为不同环境不同要求时改性材料的选用提供适用性参考,并应用此模型分析得出了兰州市沥青路面的改性材料适用情况。
Analytic hierarchy process, combined with the main road performance asphalt pavement, asphalt pavement to determine the modification factor hierarchy diagram. Three kinds of materials such as SBS, PE and EVA are taken as the research object of the performance of asphalt pavement modified materials, and the applicability analysis model is established to construct the judgment matrix through this model to solve the eigenvector. Finally, according to the sorting results, The improvement of pavement performance to determine the applicability of three kinds of materials for different environments, the selection of modified materials to provide applicability of reference, and the application of this model analysis of the asphalt pavement in Lanzhou City, the application of modified materials.
