Asphalt Additive Technology

Recycled cellulose fiber additives make asphalt more durable.

Stone Mastic Asphalt (SMA) is an excellent surface material for roads with heavy traffic. Adding recycled cellulose fiber into stone mastic asphalt results in better road surface performance. Recycled cellulose increases the absorptive capacity of bitumen and makes the road more durable. This results in better asphalt quality and road performance, and ultimately better traffic safety. Makron has the technology to produce sustainable cellulose fiber from recycled raw material.

Process stages

Excess pulp, paper, and cardboard materials are collected from various sources, for example from print houses, cardboard manufacturers and households. The recycled cardboard or paper is transported to an asphalt additive production plant. Makron Fibretec production line takes care of the whole recycled cellulose fiber manufacturing process, from receiving the raw material, to crushing it and processing the material at different stages, to producing a finished and packed product in either pellet or in loose form. Asphalt manufacturers then mix the additive into asphalt.


Longer maintenance cycles

Adding sustainable cellulose fiber into Stone Mastic Asphalt (SMA) makes roads more durable. This leads to a longer maintenance cycle for better cost efficiency.

Better traffic safety

Higher quality and more durable asphalt results in better road performance and ultimately in better traffic safety.


Less deformation and fewer fractures

Cellulose fiber additives increase the absorptive capacity of bitumen, which results in better moisture resistance.

Wear resistant asphalt

Cellulose fiber additives increase the wear resistance of bitumen.
