Riverview Blvd. in along the Mississippi River in far north St. Louis is a problematic pavement, requiring frequent re-repair.
The Missouri Department of Transportation (MoDOT) maintains this stretch of roadway that connects a long-haul truck terminal area with I-270, linking east-west I-70 and north-south I-55 in the metro area. The resulting heavy traffic has mercilessly punished the pavement. A particular area of degradation lies at the base of a bluff, from which water seeps, and the pavement is continually wet. In addition to this surface water, the roadway is subjected to water permeating up through the road material due to hydrostatic pressure. Locally available cold mix and hot mix asphalt had been used previously on this area, with premature failure, and constant re-repairs every 10 days. MoDOT was interested in finding a permanent solution that would alleviate the labor and equipment commitment this single location was eating up.
