Experiment Data Analysis of Comparative Test Research on Expressway Asphalt and Asphalt Mixture

Abstract:

Nine test lab comparative test indexes of asphalt and asphalt mixtures are analyzed by consistent statistic analysis method of ASTM E691 and Robust statistical analysis method, analysis results indicate that two methods are basically in consistent with each other, but dubious analysis index is added in Robust statistical method, and reliability is possibly enhanced on data analysis. Combined with advantages and disadvantages of two methods, the paper suggests that two statistical method can associated with each other in statistical data analysis.
