Russia-located Uralasbest manufactures basalt fiber additive for asphalt concrete

Stilobit, a stabilizing additive containing basalt fiber, is manufactured by the subsidiary company of ОАО Uralasbest. It extends service life of the road surface, makes it resistant to rutting, and prevents segregation of asphalt mixture.

The main activity of Global Basalt Engineering LLC is creation of effective productions on release of continuous basalt fiber (СBF) with technologies of the last generation and composites on the basis of СBF (Basalt Fiber-Reinforced Polymer Composites as BFRP).

This additive was used for the construction of many roads in the Moscow and Leningrad regions, Avtodor toll motorways, the Olympic facilities in Sochi.

Stilobit contains basalt and chrysolite fibers impregnated with a bituminous binder. It is the basalt fiber that makes the composition resistant to rutting, and provides asphalt wearing course reinforcement. Chrysolite increases the fatigue strength of asphalt concrete, replacing cellulose offered by import counterparts of Stilobit.

The product is sold in all regions of Russia, and also is exported to Kazakhstan and Belarus, showing the growing demand. However, a limit of production capacity currently makes 15,000 tonnes, and it is an annual output of basalt fiber stabilizing additive. Thus, an additional line is scheduled to be launched in 2017.

A group of scientists headed by professor V. Mozgovoy suggested applying composite rebar to protect roads from damage caused by ruts.
