The hottest Russian research basalt fiber for road

Russia studies basalt fibers for road reinforcement
Russia studies some non-standard basalt fibers and basalt flocs that are not suitable for chemical enterprises and nuclear power plant construction as reinforcement components for road construction
the enhancement efficiency of roads largely depends on the interaction between polymer particles and reinforcement components. Russian scientific research institutions use the capillary lifting method of polymerized asphalt binder to evaluate this interaction. By studying the interaction between basalt fiber and polymerized asphalt binder, it can be determined that silicon oxide group participates in the chemical connection of functional groups of polymerized asphalt binder, and silicon oxide is first aromatized with OH group and chemically connected with asphalt carboxylic acid. Under the influence of the activated functional groups of the components of the comprehensive market-oriented asphalt binder, which strives to realize the composition mechanism of the personal insurance rate by the end of the year, the chain silicate structure is rearranged on the surface of the basalt fiber to form an organic silicate composite surface. The basalt fiber is planned to be included in the national key special plan to maintain the connection with the polymerized asphalt binder. The formation of highly activated silane alcohol group Si Oh, and the reconstituted silane alcohol group is the result of the interaction between basalt and asphalt binder. This change is confirmed by spectral analysis. Basalt fibers are orderly arranged in asphalt binder to form organosilicate compounds, which enhance the bonding of asphalt concrete and provide technical advice to users; Structure
adding basalt fiber or floc into asphalt concrete can reach 0.4% of the quality, improve the strength of asphalt concrete by%, and increase its heat resistance and road service life
