Effect of filler types and asphalt penetration grade on properties of asphalt mastic

摘要

In order to investigate properties of asphalt mastic containing limestone, pumice and natural zeolite fillers with three penetration grades of asphalt (50/70, 70/100, 100/150) experiments were performed in this study. For this aim, temperature sensitivity and softening point tests were conducted to mastics. The results indicated that the, zeolite has better high-temperature properties and limestone has better low-temperature properties. The results also analyzed by ANOVA statistically using SPSS software, which showed significantly affect the related properties of asphalt mastics.
