The binder layer is large aggregate mixed with oil, making it very strong and durable. The binder layer can be thought of as the strength of any new asphalt surface. Step 6: Install New Asphalt Surface. Once the supportive structures of a new asphalt surface are installed, the top layer of fresh asphalt is added to provide a clean, smooth ride.

Finally, aggregate moisture impacts the amount of preparation that aggregate needs before use. The more water that is present in an aggregate sample, the more time and money must be used to dry it at the asphalt plant. Because water weakens the asphalt-aggregate bond, it is essential that it is removed before use in pavement.

What is Asphalt Aggregate? (with pictures)

Robert Robillard Many parking lots are paved with asphalt. Asphalt aggregate consists of the bits of rock and gravel that are typically seen in an asphalt, or "blacktop" surface. Some standard components of asphalt aggregate include sand, gravel, crushed stone and slag.These aggregates not only add strength to the finished asphalt concrete, they also are used without the asphalt …
