Abstract
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. The mixture of zeolite and hydrated lime is easier to handle and integrate into a process than use of either compound alone, and it offers a number of other benefits.
