A pulverizer rips up the old asphalt and base. |
|
|
A grader brings the road to the desired grade, making it passable for temporary traffic. |
|
|
Next, a truck spreads a prescribed amount of cement over the pulverized road base. |
|
|
Hooked up to a water truck, the pulverizer mixes the cement, water and pulverized roadway down to a depth of 6 to 10 inches. |
|
|
The base is compacted, cured, and topped with a riding surface, usually a chip seal or hot-mix asphalt. |
