Asphalt pavement method exclusively for bus lanes that improves pavement performance by resisting high shear forces of bus lanes and bus stops
Application
Materials
Epoxy | Elastomer asphalt modifier (RMC) | Fiber |
- Epoxy for asphalt - Main resin and hardener - Ultra strength - High water resistance | - Performance grade : PG 82-34 - High and low temperature properties improvement | - Tensile and shear resistance improvement - Crack resistance improvement |
