JT T 533-2020 Fibers for asphalt pavement.
Wood fibers. Plant fibers made from wood as raw materials for chemical or mechanical processing, as well as waste paper processing with wood fibers as the main component.
made of plant fibers.
Mineral fibers. With basalt as the main material, flocculent fibers formed by high-temperature melting, high-speed centrifugal rotation, purification processing and cationic infiltrating agent treatment, or.
Bundled fibers that are melted at high temperature, brushed, treated with lipophilic sizing, stranded and wound, and cut short.
Polymer fibers.
Chemical fibers made from synthetic polymers.
Test method for granulant content and rotational viscosity of granular wood fibers.
