ASSESSMENT OF THE TRANSPORT AND OPERATIONAL CONDITION OF ROAD PAVEMENT AND SELECTION OF AN EFFECTIVE REPAIR TECHNOLOGY

The paper proposes a pavement-condition assessment approach based on both distress type and deterioration mechanism. Using the km 46-60 section of road 4R140 as the study object, visual records of cracking, potholes, rutting, settlement, and edge failure are linked to measurements of structural response, roughness, skid resistance, and drainage performance. Because verified diagnostic results were not provided, no invented distress percentages or remaining service life are reported. A differentiated rehabilitation strategy is developed that combines local replacement of failed layers, crack treatment, profile correction, and placement of a new asphalt-concrete layer. An illustrative life-cycle calculation shows how this integrated strategy can be compared with a simple thin overlay without presenting the example as a project estimate. The final pavement design must be supported by deflection and International Roughness Index measurements, friction testing, cores, and laboratory evaluation of the existing materials.
