Use different grades of asphalt to lay the asphalt layers of a road. Lay an asphalt base layer with low bitumen content to provide a stable surface, a binder layer with intermediate bitumen content, and a surface layer containing the highest grade material with the highest bitumen content to withstand the stresses of road transport. Tend a paver to lay the asphalt or use different techniques and instruments.

Relationships with occupations
Pave asphalt layers is an essential skill of the following occupations:
Civil engineering worker: Civil engineering workers perform tasks concerning the cleaning and preparation of construction sites for civil engineering projects. This includes the work on building and maintenance of roads, railways and dams.
Road construction worker: Road construction workers perform road construction on earthworks, substructure works and the pavement section of the road. They cover the compacted soil with one or more layers. Road construction workers usually lay a stabilising bed of sand or clay first before adding asphalt or concrete slabs in order to finish a road.
Road maintenance worker: Road maintenance workers perform routine inspections of roads, and are sent out to perform repairs when called for. They patch potholes, cracks and other damage in roads.
Pave asphalt layers is optional for these occupations. This means knowing this skill may be an asset for career advancement if you are in one of these occupations.
Road construction supervisor: Road construction supervisors monitor the construction and maintenance of roads. They assign tasks and take quick decisions to resolve problems.
Rail layer: Rail layers construct railway tracks on prepared sites. They monitor equipment that sets railroad sleepers or ties, usually on a layer of crushed stone or ballast. Rail layers then lay the rail tracks on top of the sleepers and attach them to make sure the rails have a constant gauge, or distance to each other. These operations are usually done with a single moving machine, but may be performed manually.
