This document summarizes a study on the influence of mineral fillers on the properties of hot mix asphalt. The study investigated the effects of adding hydrated lime, fly ash, and phosphogypsum as fillers to bituminous concrete mix. Tests were conducted to determine the creep characteristics, stiffness modulus, and dynamic modulus of mixes containing different amounts of the mineral fillers. The test results showed that mixes with hydrated lime as a filler generally exhibited improved properties compared to mixes with other fillers or the base mix. In particular, hydrated lime led to higher creep stiffness and dynamic modulus values, indicating it improves the asphalt mix's ability to distribute loads and resist deformation under traffic.
