VARIABILITY IN MEASUREMENT OF IN-SITU MATERIAL PROPERTIES

Research is currently being conducted in Kentucky to evaluate the long term performance of several pavement sections. A total of 20 sites are being monitored throughout the state. This paper outlines the findings of the research study to date, relating to the variability observed in each of the test sections. In addition, variability at various load levels is also evaluated. Methodology is outlined regarding the use of statistics to determine the most appropriate values for rehabilitation design. Variability observed on other larger projects is also evaluated. Data is presented outlining observed annual variations in various seasons.
