Abstract:The modulus of asphalt mixture is an important parameter in asphalt pavement structure analysis.The tests for dynamic modulus and static resilient modulus were conducted reguarding three kinds of high modulus asphalt mixtures,SBS modified asphalt mixture and A-70# asphalt mixture.The distribution and influencial factors of modulus and the correlation between the two kinds of modulus were analyzed.The results indicate that the modulus of high modulus asphalt mixture is significantly larger than that of the contrastive asphalt mixture at the same testing conditions,and the magnification of dynamic modulus increases with the decrease of frequency.The static resilient modulus of asphalt mixture has an exponential relation with the dynamic modulus at low frequency,and the values of static resilient modulus can be used to estimate the dynamic modulus if the test conditions are limited.
