What We Did
Increasing ride quality was the main goal when repairing the vehicle evaluation track at Chrysler Group World Headquarters in Auburn Hills, Michigan. The 1.8-mile track consisted of two straightaways connected by a steering and handling section and two high-slope parabolic return loops, with 31 degrees (60 percent) slopes.
The project required pavement repair of failed areas, cold milling, and installation of a course with variable depth and asphalt wearing material with unique frictional qualities. Specialized equipment on the project included a custom-designed paver using a computer-controlled, high-density parabolic screed, specially designed support equipment to hold paving equipment and asphalt material transfer devices in place for work in high-slope sections, and asphalt rollers equipped with drums shaped to mirror the parabolic curvature of the track.
