The objective or this research project is to identify, quantify, and statistically characterize the components of bituminous pavements that may lead to spatial variability of pavement performance. This assessment will be based upon the extensive data set collected at the MnROAD project. Specifically, the strengths, dimensions, and magnitudes necessary for this research will be inferred from currently available Falling Weight Deflectometer (FWD) data, Ground Penetrating Radar (GPR) data, core analysis, and loading history data on the 40 various test sections. It is anticipated that a small number (e.g., < 5) of critical factors will be identified that lead to spatial variability in pavement performance. More importantly, the relative significance of each of these factors will be unambiguously quantified.
