Comprehensive Evaluation of Asphalt-Mixture Performance Based on Principal Component Analysis

Abstract:

Making the test specimen of asphalt mixture, testing the parameters of specimen, such as bulk specific gravity, percentage of voids in aggregate, percent bitumen volume in asphalt mixtures, asphalt saturation,percent voids in coarse mineral aggregate, marshall stability, dynamic stability, marshall residual stability ratio, freeze-thaw splitting strength ratio. Based on the method of principal component analysis, the items of principal component and the contribution rate will be calculated. With the cumulative contribution rate of 90% for the standard, the principal components will be selected. Taking the contribution rate as the weighting, the comprehensive score will be calculated. The research shows that using the method of principal component analysis to comprehensively evaluate asphalt-mixture performance is workable.
