Abstract:
In order to guarantee asphalt concrete deck pavement's good performance of anti-water damage and anti-rutting, the paper specially studied the influence factors on the volume parameter of the asphalt mixture used in concrete deck pavement after bridge broadened. Taking three gradations of AC-13 mixtures as research object and through Marshall and Rutting test, the paper analyzed the influence factors of the volume parameter of AC-13 asphalt mixture including asphalt contents, the volume of air voids, voids in mineral aggregate and voids filled with asphalt. The results show that under the same test conditions, with the increase of rolling times, the volume of air voids and voids in mineral aggregate decrease gradually, but the voids filled with asphalt increase continuously; under the same compaction work conditions, volume of air voids of AC-13 in the rutting depth(when the content of the asphalt is about 4.0%)is nearly the same as that in asphalt mixture not undergoing rutting test, but with the increase of the content of the asphalt, the volume of air voids of asphalt mixture on both sides of the rutting depth constantly decrease, which is less than that not undergoing rutting test. 5 tabs, 2 figs, 15 refs.
