Pavement Condition Survey at a Motorway Section in Croatia: Maintenance and Rehabilitation Activities

Abstract

The condition of semi-rigid pavement at the motorway section from Zagreb to Kutina, initially opened to traffic in the late 70s, is described and the plan for maintenance and rehabilitation work by individual subsections is outlined. A detailed account is given of the method used to determine types of pavement damage (cracks, evenness, rutting and skid resistance). The evaluation of pavement condition was performed using the pavement surface condition index (whose values range from 0 to 5) based on the OECD methodology for assessment of pavement condition. The resulting maintenance activities may be described as complex and rather extensive tasks that must be repeated in appropriate time intervals and which will significantiy improve motorway pavement serviceability. Based on preliminary analyses, the proposal is given for the maintenance and rehabilitation of driving, overtaking and stopping lanes for individual motorway subsections.
