Approval reflects alignment with evolving regulatory and performance standard for German market requirements

Ingevity Corporation (NYSE:NGVT) today announced Evotherm® P35 warm-mix additive has received approval from Germany’s Federal Highway Research Institute, known as BASt, for use in warm-mix asphalt applications. Approval signals that Evotherm® P35 meets the institute’s rigorous requirements, positioning the technology for use in one of Europe’s most demanding regulatory environments.

The approval follows several years of technical evaluation, including performance testing alongside conventional hot-mix asphalt under real-world traffic and environmental conditions.
