Road Contractors Insurance Minnesota Policy Information
Road Contractors Insurance Minnesota. The services that street, highway, and road contractors provide are in high demand. Roadways across the country need to be repaired, improved, and expanded, and new roadways need to be installed.
Street and road contractors build, maintain, or repair streets, highways, and interstates. After the route is designed and the land cleared, road construction consists of grading and leveling the earth, laying a bed of gravel, laying down the subsurface road bed (usually of cast-in-place reinforced concrete), surfacing the road with pavement, drying and curing, and marking lanes and crosswalks.
For some projects, mesh or reinforcement bars (rebar) will be used to strengthen the finished pavement. Road contractors may perform all of these operations or just the subsurface work. Bridges, underpasses and viaducts, and projects over or near water involve additional steps.
Surface work includes laying down the uppermost surface of asphalt or concrete which must withstand wear-and-tear from tire friction and the elements. The surface may be made of asphalt or concrete. A cold or hot mixture may be used. Cold mixtures are often used for temporary repairs and patching as they can be used at lower temperatures, but they are not as strong or durable as a hot mix, which is a combination of asphalt and concrete.
