Forensic Evaluation of a Rigid Pavement

Several new warehouses for an oil drilling equipment manufacturing company were constructed in 2012 in Houston, TX.  The warehouses were surrounded by three large reinforced concrete drive lanes utilized for delivery and pick-up of large-size oil equipment parts.  Shortly after construction, the reinforced concrete pavement exhibited distress in form of spalled joints at dowel locations, pumping, and localized panel failures.  CA was retained to determine the cause(s) of the distress and provide repair recommendations.  CA’s field work included soil sampling and testing, non-destructive testing of the concrete pavement, including the use of ground penetrating radar, and relative elevation surveys to verify surface drainage patterns.  In addition to the field work, CA also performed an analysis of the pavement design to determine its structural adequacy as-designed.  Ultimately, the cause(s) of the distress was determined and a repair plan was recommended.
