The Research on the Index of High Temperature Performance of Asphalt Mixture in Airfield

In order to solve current airfield asphalt road surface high temperature performance evaluation index defective problem, we apply the humbug wheel tracking test, general rutting test and uniaxial penetration test ,and use different evaluation index to carry on the analysis. Test results show that shear strength index and rutting test index on the contrary, regression dynamic stability can't distinguish between SMA - 13 and AC - 20 high temperature performance advantages and disadvantages, creep slope and dynamic stability index consistent; At the same time, the use of bailey method design parameters and asphalt cement parameters on its verification found that bailey method can further explain mixture grading high temperature performance advantages and disadvantages, ratio of filler to bitumen and dynamic stability, shear strength, creep slope has a good correlation, and asphalt film thickness and its correlation is poor. So suggest using dynamic stability and humbug wheel tracking creep slope, rutting depth combination evaluation mixture at high temperature performance advantages and disadvantages.
