Effect of Fillers on the Moisture Resistance and Performance of HMA

The main objectives of the proposed study are two-fold: (1) To evaluate the effects of various types of inert and active fillers on the moisture resistance and laboratory performance of asphalt mixtures. (2) To propose change to the specifications to optimize the use of mineral fillers in hot-mix asphalt (HMA).
