Study on Splitting Performance of Non-uniform Asphalt Mixtures Under Different Influencing Factors
To study the mechanical properties of non-uniform asphalt mixtures under different influencing factors,the splitting test of asphalt mixtures with different degrees of segregation was carried out under different loading rates and test temperatures.Finding the more asphalt mortar content in the internal asphalt mixtures with different segregation degrees of the same grading,the splitting strength is affected by the change of temperature and loading rate is more significant.After aggregate segregation occurs,the more internal fine aggregates,the more structural asphalt,the higher the splitting strength.AC-13 shows better splitting performance than OGFC-16 under each degree of segregation.
