Concrete pavement response to temperature. Civil engineers at West Virginia University have developed a three-dimensional model to predict the response of jointed concrete pavement to temperature variations ( The International Journal of Pavement Engineering , Sept. 2004). To validate the model, its predictions were compared with field measurements of key concrete stress variables taken at a newly constructed highway. One variable measured was slab top transverse strain (i.e., change in length per unit length per unit time) at a distance of 1 meter from the longitudinal joint. The 5-hour changes (8:20 p.m. to 1:20 a.m. ) in slab top transverse strain for six days are listed in the accompanying table and saved in the SLABSTRAIN file. Analyze the data, using a nonparametric test. Is there a shift in the change in transverse strain distributions between field measurements and the model? Test, using α = .05.
