Research on Old Asphalt and the Regeneration Agent Compatibility Test

Abstract

The key to recycling of old asphalt mixture is waste asphalt recycle, three regenerants were used as modifiers for old asphalt mortars, three major indexes and rotary viscosity after mixing it with waste asphalt recycle and measured, and simulating a transfer of the old asphalt mortars, then which evaluate on compatibility of the old asphalt and regenerant, to provide reference basis for the choice of regenerant.
