Arizona DOT Specification- Asphaltic Concrete Friction Course ( Asphalt-Rubber)

Asphalt-rubber asphaltic concrete friction course (ARACFC) is the asphalt rubber version of the 407 Standard Specifications for ACFC. Crumb rubber is blended with the asphalt cement to form an asphalt-rubberbinder. The blending takes place in a reaction tank at temperatures between 325°F (163°C) and 375°F (191°C) for at leastonehour. During this time,the rubber partially melts and is thoroughly mixed with the asphalt cement to form a binder material.
