Cellbit and Cellbit 10 – Cellulose Pellets

Project Info

Case Study

Raw wood cellulose pellets mixed or not mixed with bitumen for the construction of mainly SMA roads or highway projects.


Stone Mastic Asphalt (SMA) was developed in Germany 30 years ago.Since then it has spread throughout Europeand across the world. In Germany alone approx. 100 million square metres areapplied every year. The resistance to permanent deformation on heavily trafficked roads is a result of the high content of large sized aggregates. This causes a distinct mineral aggregate distribution, hence SMA is also known as gap graded asphalt. The aggregate structure is firmly bonded togetherby a strong aphalt mastics consisting of sand, filler,bitumen binder and CELLBIT 10 fibres.
