Minnesota Road Research Project: Forensic Investigation 199701
This report focuses on the first extensive forensic excavation of a paved test cell at the Minnesota Road Research Project (Mn/ROAD). A trench was dug in Cell 28 of the Low Volume Loop at Mn/ROAD to investigate a localized failure of the roadway. This report documents the trenching process and serves as a historical record of the in situ conditions of Cell 28 in the early summer of 1997. Data collected during this forensic excavation had contributed to the conclusion that mechanistic pavement design methods should include a maximum allowable stress criteria for aggregate base and subgrade. In addition, minimum hot-mix asphalt pavement thicknesses are required to prevent failures of aggregate base and subgrade. The tests performed during the investigation, as well as the analysis of available data, are discussed. The conclusions of the forensic research team as to the historical performance and subsequent deterioration of Cell 28 also are included.
