Permanent deformation in asphalt pavement structures is one of the main pavement distress problems. The common asphalt pavement surface deformations are shoving and rutting at intersections, bus stops and bays, in heavy vehicle loaded urban streets due to acceleration, deceleration, slow moving or standing. It was determined that in many cases the failure was caused by asphalt layers fatigue and low resistance to shear flow. The laboratory research of high modulus asphalt concrete mixtures with different aggregate and binder types showed good results for city streets pavements performance improvement.
