In a head-to-head pavement competition that started in 1994, the asphalt section is still going strong, but the concrete one has been completely removed and replaced with asphalt.

Some transportation agencies today share the belief that Hot Mix Asphalt (HMA) pavements in high-stress intersections will rut. These same agencies believe that building high-stress pavements using Portland Cement Concrete (PCC) is the only effective means to remedy this problem.
