HYDRATED LIME ADDED DIRECTLY TO ASPHALT CEMENT AS A MULTI-FUNCTIONAL MODIFIER FOR ASPHALT MIXTURES

摘要

A hot mix asphalt composition and method are shown in which hydrated lime is added directly to the asphalt binder prior to the addition of the asphalt binder to the mineral aggregate constituent of the composition. The lime-asphalt mixture is then added to the mineral aggregate. The lime component is added to the asphalt binder in an amount which exceeds about 10 % by weight, based upon the total weight of asphalt binder in the composition.
