Cellulosic Fibers

Cellulosic fibers are one of the main components of TMA (Stone Mastic Asphalt). Together with bitumen, fine aggregates, and fillers, they form the "mastic" part of the TMA. This mastic section fills the voids between the coarse aggregates, allowing the stones to touch each other, which is what makes TMA the most robust asphalt paving system known.

In TMA, cellulosic fibers help prevent bitumen runoff, seepage, and shedding, which can occur due to the high amount of bitumen used in the mix. These fibers ensure the stability and integrity of the bitumen, enhancing the overall performance of the asphalt.
