Embodiments are presented herein that provide a filler that is a combination of zeolite and hydrated lime. Addition of this filler to asphalt is more beneficial than addition of either zeolite or hydrated lime alone. The beneficial properties of zeolite include a controlled release of moisture that aids mixture workability and the ability of the asphalt to effectively coat the aggregate particles.
