MEASUREMENT AND PREDICTION OF FORWARD MOVEMENT AND RUTTING IN PAVEMENTS UNDER REPETITIVE WHEEL LOADS

A three-dimensional mechano-lattice stress-strain analysis has been used to predict rutting and permanent forward displacement behavior of pavements subjected to 14,630 one-directional passes of a 226-kg (500-lb) loaded pneumatic tire under very well-controlled conditions. The two pavement sections tested consisted of crushed prospect dolerite with 10 percent clay, each placed in an indoor test track with different compactive efforts and moisture contents and a thin coating of bituminous materials. The favorable comparisons between these predictions and the measured values seem to support the mechano-lattice analysis as a pavement analysis tool. (Author)
