You use asphalt every day. But have you ever stopped and wondered to yourself, “Hey, how is asphalt made?” If so, you are not alone. Despite being such an integral part of everyday life, few people know how asphalt is made.
So, without further ado, the process for making asphalt!
- Predose: A belt weigher is used to weigh the aggregate components of asphalt pavement. A belt weigher is used so that the materials can simultaneously be weighed and taken to the next step in the process.
- Drying: The asphalt components are dried in a rotary drying drum at roughly 300 degrees.
- Reweighing: Since drying can alter the weight of the aggregate, it has to be reweighed after drying.
- Storage: The dried components are then sifted and store in silos.
- Mixer: After being transferred to the mixer, binding element, or liquid asphalt is added to the aggregate. Both aggregate and binder are mixed thoroughly to form the paving material.
- Storage Round 2: After mixing, the asphalt is stored in a heated silo. If the asphalt mix cools it cannot be compacted.
- Application: The asphalt is transported by dump trucks to the job site for application.
Hopefully now you know a little bit more about asphalt than you did before!
