Performance Investigate of Fine Aggregate Size and Content on Asphalt Mastic

Article Preview

Abstract:

The objective of this study is to investigate and evaluate the compressive strength and creep behavior of fine aggregates on asphalt mastic. The variables that are considered in the study include the size and content of fine aggregates. Eight types of mastic specimens consisting of bitumen with various volume fractions of different kinds of fine aggregates were used. Unixal compression and static creep tests were realized at different loading conditions. The results found that, in general, asphalt mastics made with different aggregate sizes but same volume fraction (64%) have slight difference in compressive strength and creep values. However, those values show significant differences for mastics made with different volume fractions but same aggregate size (between 2.36 and 1.18 mm). Moreover, the asphalt mastic with 64% volume fraction has better deformation resistance.
