Crushed Asphalt Driveway (Reasons to Choose) - Designing Idea

Crushed asphalt is also called pavement milling, asphalt milling, and recycled asphalt pavement. It's essentially made of former asphalt roads or projects that have been crushed into gravel. Once this has been properly crushed and screened, the end result is a very high-grade and high-quality aggregate that's coated with asphalt cement.
