The article Effect of Granular Subbase Thickness on Airfield Pavement Structural Response (K. Gopalakrishnan and M. Thompson, Journal of Materials in Civil Engineering, 2008:331342) presents a study of the effect of the subbase thickness on the amount of surface deflection caused by aircraft landing on an airport runway. In six applications of a 160 kN load on a runway with a subbase thickness of 864 mm, the average surface deflection was 2.03 mm with a standard deviation of 0.090 mm. Find a 90% confidence interval for the mean deflection caused by a 160 kN load.
