Roadways

First, the contractor builds embankments using cuts and fills.
Next, a grader or bulldozer levels the screened dirt and fills in dips to create a surface that will support a road for decades.
After the ground is leveled, 6-8 inches of R1 type RCA is installed and compacted.
During the next step, the contactor installs drains and sewers. The center of the road must be higher than the edges of the road in order for water to properly drain into the storm sewers. Drainage is a critical element because improper drainage will greatly reduce the new pavement's life expectancy.
For lighter traffic roadways, 2-3 inches of Type 3 binder is laid and compacted followed by 1½ to 2 inches of Type 6 or Type 7 top.
For heavy highways, 4 inches of Type 1 base is first laid, followed by 2-3 inches of Type 3 binder, finished off with 1 ½ to 2 inches of Type 6 or Type 7 top.
Asphalt uses bitumen, a petroleum product, to glue together sand and crushed rock. This mixture is heated to approximately 300 degrees at the asphalt plant then it is trucked to the construction site where workers spread and compact the hot mixture onto the roadbed.
All of this work must pass strict inspections before the project can continue.
