Generally it's crushed and a percentage of the final mix uses the recycled crushed asphalt. The quality of the asphalt is lower with higher amounts of recycled materials so high traffic roadways like highways may use 30% recycled asphalt. While lower traffic roadways or things like bicycle paths can use a higher percentage with new binder in the mix.
