Variability In The Hamburg Wheel-Tracking Device (Hwtd) Data And Results, Ilerioluwa S. Giwa
LSU Master's Theses
Over the years, the Hamburg Wheel-Tracking Test (HWTT) has become one of the most popular devices used for characterizing asphalt mixtures for rutting potential and moisture susceptibility. However, although the HWTT is a reliable standard test for evaluating asphalt mixtures, it is not exempt from variability in the test data and result. Variability in the HWTT test data and results have been majorly attributed to imprecision in the test practice and due to some limitations in the HWT device setup.
The primary goal of this study is to evaluate the variability in the HWTT data and result by investigating a …
