Asphalt contains bitumen which acts as a binder for mineral aggregates such as sand and rocks, and is also referred to as blacktop or pavement. Poor quality asphalt can result in rutting, cracking, polishing, bleeding, weathering, potholes and other forms of pavement failure or loss of grip on the road surface.
Ideally, the aggregate would also be produced from limestone to minimize the risk of poor adhesion (stripping) occurring between the stone and asphalt, which is common with siliceous aggregates like granite. If left untreated, stripping can result in premature cracking, rutting, and reduced pavement.
Chip seal equipment is mainly used for evenly spraying liquid asphalt and clean dry aggregate on the pavement. Chip seal equipment is mainly composed of a chassis, asphalt distribution system, aggregate distribution system, gas path system, waterway system, control system, radar speed-measuring device, dynamic system and mixing system.

At one time it was thought that a prime coat was an essential element of good pavement construction. However, in recent years some engineers have eliminated the use of a prime, especially when asphalt layer(s) (surface and/or base) is 4 inches or more in thickness.
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.
Aug 27, 2020 Aggregates are the most basic material used in construction. They provide the foundation for roads, bridges, and buildings, while also making up over 90% of an asphalt pavement and up to 80% of a concrete mix. On average, 38,000 tons of aggregates are necessary to construct one lane mile of interstate highway.
