The Method in Which Asphalt is Produced
Asphalt is formed in an asphalt plant and it can either be a mobile mixing plant or a fixed plant. Asphalt plant can be produced up to 800 tons/hour and the hot mix asphalt’s average production temperature happens to be between 150°C and 180°C. However, with the help of the novice technologies, asphalt can be produced at low temperatures too.
The Reasons Behind Using Asphalt in Place of Concrete
Once concrete was used to pave parking lots, roads, and other projects, but asphalt paving is highly preferred today. Concrete is formed using aggregate, such as sand and crushed rock besides water and cement. When the mixture dries, it becomes an unforgiving and stiff solid which becomes susceptible to breaking and cracking, particularly when the surface underneath it happens to be uneven.
Similar to concrete, asphalt is prepared with the use of aggregate. However, its binder happens to be bitumen which is a sticky and dark substance which is the resultant of crude oil. When parking lots, roads, and driveways are constructed with asphalt construction, then hot asphalt is poured into a bed of weightier aggregate before pressing it with the help of a steamroller.
With the cooling of the asphalt with the surrounding temperature of the air, it becomes sufficiently strong to survive automobile traffic. Though asphalt happens to be excessively durable and hard, yet it proposes sufficient flexibility for accommodating limitations in underlying surfaces which is a feature which concrete lacks.
Asphalt happens to be a 100 percent recyclable item and because of the demand of asphalt for the purposes of recycling, this material hardly takes up valuable and confined landfill space. The construction projects of asphalt can be opened and finished for traffic faster compared to concrete construction projects.
The repair and maintenance of asphalt pavement happen to be less expensive and faster compared to cement pavement too. Repairing little cracks in asphalt walkways and driveways is very easy and so, homeowners can handle the maintenance project themselves.

The Components of Asphalt
The constituents of asphalt comprise four chief classes of compounds:
- Polar aromatics that comprises high molecular weight phenols plus carboxylic acids that are formed by the material’s partial oxidation.
- Naphthene aromatics that comprises of a partly hydrogenated polycyclic aromatic compound.
- Asphaltenes comprising high molecular weight phenols plus heterocyclic compounds.
- Saturated hydrocarbons are the percentage of asphalt’s saturated compounds which associate with its softening point.
