dc.description.abstractIn New Brunswick, the occurrence of wheel track rutting in asphalt concrete is becoming increasingly common. So common, that the New Brunswick Department of Transportation has begun to investigate the extent of rutting and possible causes. This paper utilizes some of the data which has been collected by N.B.DoT., to further investigate rutting due to plastic deformation of the asphalt layers. Twenty-four sites were selected across the province with varying age and rutting performance. The rutting performance of these sites was related to several asphalt concrete parameters using a regression analysis and threshold analysis. The parameters which were studied include; air voids, asphalt content, voids in the mineral aggregate, fractured faces and Marshall stabi1ity. The regression analysis indicated that the rate of wheel track rutting did not correlate well with any of the parameters. The threshold analysis was used to identify a parameter value which separated sites with acceptable and unacceptable rutting performance. Conclusions are drawn regarding the effect of the selected asphalt parameters, and some recommendations are made regarding further research.
