       Notes - general: The effects on pavement wear of changing the
                        trafficking line on a DBM pavement were estimated
                        using elastic theory.  This was followed by an
                        accelerated trafficking test on a DBM pavement at the
                        Pavement Test Facility, to allow the theoretical
                        estimates to be tested.  Pavement wear in the
                        trafficking test was assessed in terms of cracking
                        measured at the pavement surface and permanent
                        deformation.  The rate of  cracking was substantially
                        reduced following the change of the trafficking line
                        and final deformation was uniform over a wide part of
                        the trafficked area.  Both results were broadly in
                        line with theoretical predictions.  However, only
                        quite small amounts of  deformation were produced in
                        the test, due to the strong foundation.  The results
                        may not, therefore, necessarily apply to major
                        structural rutting; a weaker foundation would probably
                        have to be used in the PTF to simulate the development
                        of major ruts under traffic.
