Abstract
The property of aggregate has a significant effect on the performance of asphalt mixture because of its high proportion. Asphalt mixture prepared by some kind of aggregate cause the inadequate compaction problem, which results in moisture damage due to its large air void. Limestone manufactured sand is considered as one of the useful solution to overcome the compaction problem. In this paper, fine aggregate is substituted by different proportion of limestone manufactured sand (LMS). The effect of replacement ratio on volume properties and pavement performance is studied. The results show that the limestone manufactured sand can improve the pavement performance and is benefit to the compaction of andesite asphalt mixture. Furthermore, this research also provided some valuable parameters for guiding the pavement construction in the future.
