The pulverizing process allows all these goals to be met. Pictured at the left is a pulverizing machine, working on the primary access roadway to the Kenosha County Airport. The machine reduces the existing asphalt pavement to a crushed aggregate base course and blends it with the underlying base material. The composite mixture is then shaped, watered to optimum moisture content and compacted. The new base can be opened to traffic immediately behind the process while it awaits the placement of new HMA pavement.
Traffic continues to flow on the important access road.
In the photograph to the right, the entire pulverizing equipment train can be seen. The pulverizer is being followed by a vibratory roller, providing the new base surface. The grader can be seen shaping the processed material in the shoulder area. Once the new pavement is constructed, it will begin an entire new service life, essentially free of any reflective cracking. Throughout the process, no material was wasted, traffic was not inconvenienced unduly and the time required to complete the work was reduced to a minimum.
