Grants and Contracts Details
This section of roadway was constructed in the mid 1980's of 10-inch PCC pavement on six inches of DGA. The driving lanes in each direction have exhibited mid-slab transverse cracking along with differential settlement relative to the inside lane and the outside shoulder. In addition, faulting of the transverse joints and at mid-slab cracks has also been observed. The causes of these distresses are not entirely known at this time. A rehabilitation plan has been developed to replace the existing driving lane in both directions. At the present time, the inside lane has exhibited some transverse cracking in a few isolated areas, but has not exhibited the settlement which has occurred in the outside lane. To assist in the evaluation of the rehabilitation alternatives, the Transportation Center will conduct a field evaluation to determine the in-situ pavement conditions. This investigation will include Falling Weight Deflectometer Testing, pavement coring and subgrade investigation, along with ground penetrating radar surveys.
