Paving contractors work on various projects in the construction industry. Paving companies require personnel skilled in laying asphalt and mixing concrete. Putting together block or slab patios requires a different level of skill. Some may also hire bricklayers.
Asphalt or blacktop surfaces have to be laid in precise weather conditions. They also need regular maintenance. A blacktop driveway has to be resealed every year, done by the application of a coat of coal tar. Because of this, some homeowners prefer concrete driveways, which generally require less maintenance. Some contractors may specialize in one or the other. Paving materials need to be mixed using special equipment and machines. Contractors hire drivers to move equipment to and from the work site, as well as workers to perform the actual building of the paved area.
Asphalt and concrete are laid on top of fill material. Gravel is placed over a layer of scalping stone. Some contractors may only lay gravel and maintain gravel spaces, which commonly requires the addition of new stone.
Paving contractors may build new paved areas, in such cases the contractors are often involved with the design process. They may also completely resurface areas. However, much of their work is routine maintenance and repairs. Patching cracks in both asphalt and concrete surfaces is essential. They may also replace large paving stones on a patio.
Some contractors mostly do residential paving work, including driveways, car ports and patio areas. Others do larger scale projects that might include corporate parking lots and private roads. Road repair itself is often handled by government personnel, but this too may be outsourced to contractors.
Paving maintenance and replacement will continue to be a prospering industry.
