Statistical Analysis of Unbound Subgrade Pressure Measurements
The objective of this paper is to present statistical analysis of unbound subgrade pressure measurements. A heavily instrumented, flexible pavement was constructed and received an uncharacteristically low amount of rainfall for several months thereafter. The large amount of data acquired under the relatively constant moisture conditions during this period served as an excellent tool to analyze variability form a full scale pavement test, especially in the context of measurement redundancy and appropriate analysis techniques. The analysis presented in this paper focuses on measured subgrade pressures and is part of a more comprehensive effort to assess all pavement layers. It was shown that sensor redundancy alone may lead to erroneous conclusions if the redundancy is taken as a substitute for variability analysis. Future work aims to demonstrate optimal techniques useful for generating meaningful conclusions by incorporating sensor redundancy, measurement variability, and construction variability.
