Massachusetts companies launch additive for recycled asphalt

The Warner Babcock Institute for Green Chemistry LLC (WBI) and Collaborative Aggregates LLC, both based in Wilmington, Massachusetts, have announced the commercial availability of Delta S, which they describe as “an easy-to-use liquid additive that reverses aging and oxidation in reclaimed asphalt for exceptional performance and longevity.” Delta S also performs as a warm-mix asphalt (WMA) additive, significantly reducing paving temperatures and minimizing energy consumption, according to the companies.

Delta S is designed for use in any traditional hot-mix, recycling, in-place recycling or warm-mix asphalt application. Renewably sourced, this plant-based solution is designed to reduce paving costs by increasing the amount of reclaimed asphalt that can be effectively used while reducing paving temperatures needed for optimal performance, according to the companies.
