Roads are made by engineer's designing and then putting the plan together.
Construction equipment is brought in to level the area or to add material to the area that the road is to be built. Material may consist of dirt, sand concrete or tar for black tops (highways). These materials are then placed on the area and then refined.
First, the contractor builds embankments using cuts and fills.
Next, a grader or bulldozer levels the screened dirt. Leveling bumps and filling in dips creates a surface that will support a road for decades.
The screened dirt is sprayed with water and compacted to its maximum density. During this stage, the contractor installs drains and sewers. The center of the road must be higher than the edges so water will run off into the storm sewers. Drainage is a critical element because improper drainage will greatly reduce the new pavement's life expectancy.
All of this work must pass strict inspections before the project can continue.
To complete the earthwork, the contractor places gravel in 12-inch layers on the road bed. Workers moisten and compact each layer. Layers are added and compacted until the road bed reaches the height called for in the design.
