What We Did


Maintaining the integrity and individual nature of the track is critical to any race venue repaving or repair project. The MIS project, set to the exacting standards of the International Speedway Corporation Design and Development, included reconstruction of the pit road area, removal of the existing asphalt surface, repaving of the 2-mile long track and construction of a 1.5-mile long road course in the track in-field.

The pit road project was completed in just 30 days. The second phase saw completion within a tight 90-day window despite many engineering challenges. The MIS track has variable banking, with its steepest point at 18 degrees, a pitch requiring us to modify existing equipment to adhere to smoothness standards. A laser survey of more than 100 million data points guided engineers in replicating all points of the original pavement surface, maintaining the track’s unique character and track geometry.
