  • Multifunctional Additives
    Publication number: 20170306152
    Abstract: This disclosure provides for compositions and applications thereof of multifunctional additive systems for asphalt modifications. These systems comprise multiple functional additives in one source, and thus can reduce or eliminate the need for multiple redundant equipment, such as pumps and meters for the addition of each additive. In certain embodiments, the additive system is such that it can be stored and/or transferred without the need for or with reduced need for mixing.
