It can then be transported to an asphalt or concrete plant and incorporated into new pavement, or recycled in place to form the base or subbase for new pavement. Some methods used include: Inplace recycling. Rubblizing of concrete pavement. Existing concrete pavement is broken into gravelsized particles.
