Asphalt

Cellulose fibres are used in Stone Mastic Asphalt, Open Porous Asphalt and in asphalt binding layers to provide stability to the bitumen /filler matrix. Our roads are increasingly subjected to heavier traffic loading and higher traffic density and accordingly longevity and anti-rutting performance of asphalt surfaces is critical. CFF cellulose fibres have been developed over many years and are used in asphalt design worldwide providing consistently reliable performance under a variety of road user and weather conditions. CFF works alongside asphalt developers formulating designs to cater for today's and future road surface requirements.

STM CFF cellulose asphalt fibres are available as

Topcel - a single component cellulose fibre pellet.

Genicel - a multi component fibre + pellet.
