    • Abstract:
      On November 29, 2006, Fugro Consultants, Inc. (Fugro) initiated falling weight deflectometer testing on US 90 in Harrison County, Mississippi. This testing was performed in general accordance with our Work Authorization proposal dated November 2, 2006, which was authorized by the Mississippi Department of Transportation on November 8, 2006. Additionally, the investigation was conducted in accordance with the terms and conditions contained in our Master Professional and Consulting Services Agreement. Based on the limited availability of pre-existing structural capacity data, this testing was initiated with the understanding that direct comparisons of the impact of Hurricane Katrina and associated flooding could also be limited. The importance of keeping water out of pavement structures is fairly well documented (Ref. 1 & 2); however, it is believed that the data collected under this investigation should (at the very least) serve as a suitable benchmark for what the structural capacity of the route tested was (within 14 months of the flooding) anticipating that accelerated deterioration of this route is to be expected (Ref. 3).
