Asphalt Surfacing
Quality Asphalt Construction
Asphalt or Hotmix as it is often called, is produced in a plant that heats and mixes aggregate and sand then adds bitumen into a composite mixture.
Laid by Hand or Paver
Before being applied to the roadbase a bitumen primer seal or emulsion tack coat must be used.
Depending on the size of the project, the asphalt can then be laid either by hand spreading or through a machine called a paver. This is usually applied to a thickness of around 30mm thick, or more if required. It is then rolled and compacted shortly after being applied before it cools.
Asphalt & Bitumen Used Together
Asphalt has a smooth stone free surface finish and will generally cost more than bitumen due to the extra cost of materials, labour and machinery required.
Some projects are able to make use of both asphalt and bitumen. Asphalt may be used around the house while a bitumen seal can be used if a long driveway is present.
