FAQ How does E-Flex GF 250 enhance asphalt paving performance? E-Flex GF 250 significantly improves asphalt durability by enhancing flexural strength and resistance to life-shortening impacts like rutting and cracking. The carefully calibrated fibers distribute easily throughout the asphalt mix to create a robust internal structure. This reinforcement helps extend pavement life while potentially reducing overall material requirements, offering both performance and sustainability advantages. And it’s the logical way to maximize the strength and longevity of asphalt paving projects. What makes E-Flex GF 250 different from other REGEN Fiber products? E-Flex GF 250 stands apart from our other products in a unique way. While it’s made from virgin glass fibers, these materials are manufacturing scrap from windmill blade production. So while comparable to virgin fiber, E-Flex GF 250 still diverts material from waste streams —giving new purpose to clean, high-quality glass fiber that would otherwise be discarded. With fiber lengths ranging from 12 mm to 25 mm, it’s specifically engineered for asphalt paving applications. And it’s 100% recycled in the USA, supporting American jobs. What sustainability benefits does E-Flex GF 250 offer for paving projects? E-Flex GF 250 significantly improves asphalt durability by enhancing flexural toughness and resistance to wear and tear, like rutting and cracking. The fibers are easily incorporated into asphalt mixes. This reinforcement helps extend pavement life and brining long term savings for the end user, offering both performance and sustainability advantages. And it’s a logical way to maximize the strength and longevity of asphalt paving projects.
