For a period of more than six years the Research Division has had under observation the concrete pavement built without transverse joints on U.S. 31-W between Franklin and the Tennessee Line. The primary reason for observing performance year after year is to record the incidence of cracks and other more serious defects; but also the grooving of cracks in 1949 and the application of different joint sealing materials became an important part of the observations.
