Step 3: Sub-grade Preparation
The roadbed is graded to a smooth level surface. This is the base upon which special material will be placed prior to asphalt.
 
THE ROADBED IS LEVELED
Graders level the road bed, followed by a roller to compact the material. Notice the improved drainage ditch on the left.
