Asphalt Recycling

Hot recycling is the process of combining RAP with new or “virgin” aggregates, new asphalt binder, and/or recycling agents (as required) in a central plant to produce a recycled mix. Hot recycling utilizes the heat-transfer method to soften the RAP to permit mixing with the virgin aggregates and asphalt binder and/or recycling agent.
