Abstract

Wheel tracking experiments were carried out on dense graded mixes containing a commercial aggregate. The binders used in these experiments consisted of a straight AR1000 and three blends of polymer modified asphalt. In all cases the AR1000 was used as base asphalt and three different polymer types were compared. These mixes showed various propencities for resistance to permanent deformation. The results correlated well with the fundamental rheological properties of the binders.
