【 摘 要 】

The pavement performance of asphalt mixture is evaluated by several pavement performance indexes. Because of the lack of data, it is difficult to synthetically evaluate the pavement performance. There are 14 indexes of pavement performance which were taken as the original indexes. Based on the factor analysis, the 14 indexes were integrated into 3 items. Three dimensional space model is established based on this 3 items. With the factor scores of each sample, the discrete points were plotted in the coordinate. Fitting the distribution area of characteristic indexes by ellipsoid. The distribution area is independent of each other. The boundary of the fitting area is clear.
