Recycled Asphalt Driveway: ProsCons

Often referred to as recycled asphalt pavement (RAP), recycled asphalt is simply old asphalt that is then ground into an aggregate size. When it's compacted, the material is able to harden and bind together. This makes it a great pick for use on driveways because it serves as a strong and cost-efficient base or sub-base material.
