DEFORMATION PARAMETERS OF THE ASPHALT MIXTURES IN PAVEMENT CONSTRUCTION LAYERS

摘要

The quality of the road is affected by the correct design, materials used appropriately,climate impacts and technological discipline. Deformation properties of mixtures used forconstruction of pavement construction layers detected by dynamic methods and fatigue -as a functional test - allow to design the road to suit the anticipated traffic load throughoutits life. Quality of mixtures is also expressed by the resistance to permanent deformation.Complex modulus of stiffness, principal curves and fatigue can reliably characterize theproposed mixture of asphalt bonded aggregate and additives. On the circular test trackwere evaluated mixtures with conventional asphalt binder, modified binder and additives.
