Lignin fiber is an organic fiber made from waste newspaper or pulp through chemical treatment and high-temperature processing. It is mainly divided into two types: flocculent and granular.
Basalt fiber, steel fiber, and lignin fiber improve structural performance, crack resistance, and extend pavement lifespan.
Powder water reducers and anti-rutting additives integrate smoothly into mixes, enhancing workability and simplifying construction.
All products are safe, sustainable, and suitable for highways, bridges, airports, municipal roads, and heavy-load infrastructure projects.
