Effects of Asphalt Concrete Gradation, Air Voids, and Test Temperatures on Rutting Susceptibility by Using the Hamburg Wheel Tracking Device (HWTD)
This study analyses the effect of gradation in different asphalt concrete (AC) mixtures using the Hamburg Wheel tracking device (HWTD) destructive test. Eight Superpave III (SP III) mixtures with different gradations were collected in New Mexico and tested at three different temperatures (40 °C, 50 °C and 60 °C) and three different air voids (AV) contents range. Coarser and finer gradations were defined using the maximum density line. Three finer gradation and five coarser gradation mixtures were compared. Coarse gradation showed better results in all three different test temperatures and AV contents ranges. An AV contents range from 5 to 6.5 percent was considered as optimum for this study. A relation between AV contents and temperature test was not observed.
