Value-Added Reuse of Recycled Asphalt Pavements

ITRI has developed a bio-agent for asphalt regeneration that increases the bonding between new and recycled asphalt and thus improves the mutual compatibility of the materials. The agent is applicable to recycled pavements with a viscosity of up to 1 million poise, improving the ratio of recycled pavement usage by more than 40%, which effectively reduces the need for new pavement material and asphalt. ITRI has secured certification of the agent by passing weathering tests of pavements containing recycled asphalt treated with this agent. The product is now fully in compliance with legislative requirements and is competitive against imported agents in terms of cost. Additionally, ITRI has set up a demonstration platform for the trial production of asphalt regenerating agents.
