Sažetak
The measurements showed that the International Roughness Index (IRI) values for the urban transport facilities predicted for reconstruction range from 5m/km to 14m/km, and for new or already reconstructed ones the values vary about 2m/km. Usual ways of repair of the pavement facilities structures in the city of Zagreb are: 1) replacement of already existing asphalt layers with a new bituminized crushed stone material base course and wearing asphalt concrete layer and 2) performance of the new pavement structure (layer of mechanically compacted course of grain stone material, bearing layer stabilized by hydraulic binder, bearing layer made of bituminized crushed stone material and a layer of splitmastix asphalt wearing course -SMA. As a large number of urban facilities is planned for reconstruction, the study was conducted to justify each repair mode. The study proposes the IRI values, obtained from the investigation measurement results upon which the reconstruction could be carried out to get the aimed IRI values ranging up to 2m/km in the end point.
