Title: Influence of TLA ash on high-temperature performance of asphalt mortar
Abstract: The extracted TLA ash and 2 kinds of contrast mineral powders were mixed as asphalt mortars with the base ESSO A-70 asphalt.The contrast DSR experiments were made under different temperatures with different ratios of filler to asphalt.The results show that the anti-rutting factors of the asphalt mortars with ash are obviously bigger than those with contrast powders to indicate its good high-temperature performances.Meanwhile,the anti-rutting factors have good correlations of exponential function with the ratios of filler to asphalt and good correlations of linear function with temperatures.The gradients of regression formulas for asphalt mortars with ash are the biggest to indicate the obvious influence of ash on the high-temperature performances of asphalt mortars.Therefore,there is a good tough effects of ash to the high-temperature performances of asphalt mortars.
