The rapid growth of heavy traffic and increase in standard axle load has prompted scientists to research new and durable road construction materials and compounds for use in pavement structural layers. The International Roughness Index IRI and rut depth are one of the operating indices that measure the condition and lifetime of pavement structures. It is known that the quality properties of materials and pavement structural layers have a direct influence on the durability and life time of wearing courses. This article presents investigations of different quality indices of road construction materials including the service indices IRI and rut depth of wearing courses. The article will also describe and interpret how the properties and qualities of road construction materials influence and cause variation in service indices of wearing courses.

Keywords: International roughness index; rut depth; service indices; roughness; pavement structural layers; wearing courses.
