dc.description.abstractIn New Brunswick, the occurance of wheel track rutting in asphalt concrete is becoming increasingly c o m m o n .

This paper utilizes some of the data which has been collected bv N. B.DoT», to ^_ / • further investigate rutting due to plastic deformation of the asphalt layers.
