Prediction models for pavement wear and associated costs

• Prediction models that describe changes in the condition of various portions of a road structure constitute a valuable tool for evaluating the service life and economics of a road structure or of a surfacing measure. Prediction models also constitute the core of planning systems - Pavement Management Systems - which are based on changes in the condition of various road structures and asphalt layers depending on traffic and time. The prediction model discussed in this report describes the magnitude of wear of pavement and of rut formation created by vehicles with studded tyres. The objective was to develop a computer based prediction model for the rut formation that is caused by wear from studded tires. The model shall both provide a prediction of the wear resistance of the wearing course based on data regarding the type of wearing course, the properties of component materials, and a model of the rut profile based on data for type of road, traffic load, etc.
