Abstract
The effect of fine aggregates with different gradations, sizes and volume fractions on the compressive strength and creep behavior of asphalt sand was investigated by a systematical experimental study. The fine aggregates were referred to those of sizes smaller than 2.36 mm. 8 types of asphalt sand specimens were designed and used for the uniaxial compression and creep tests conducted at different loading conditions. Obtained experimental results show that the volume fraction was found to have significant effect on the properties of asphalt sand, however, the different size does not result in significant differences in compressive strength and creep behavior of the asphalt sand with 64% volume fraction of fine aggregates.
