rubberized asphalt mixing method

Glossary: Rubberized Asphalt Concrete (RAC)

Mix design of asphalt and rubberized asphalt paving mixes is a trade-off between high binder content to enhance long term durability and performance, and sufficient in-place void space to avoid rutting, instability, flushing and bleeding.

Asphalt Rubber Hot Mix-Gap Graded (ARHM-GG) Overlays

Rubberized asphalt is a hot-mixed asphalt pavement containing crumb rubber. The crumb rubber serves as a “modifier” of the liquid asphalt. It’s addition gives the liquid asphalt greater viscosity (resistance to flow) and improves other properties which re
