Abstract

Sustainable and durable road pavement requires appropriate maintenance and repair strategies. National road authorities collect data describing pavement condition every several years and use specific life-cycle analysis methods to draw up priority plans for maintenance activities. The pavement performance models (PPMs) create a basis for the life-cycle and cost-benefit analysis as they help to evaluate pavement condition as well as to predict pavement deterioration. The objective of this research is analysing different PPMs of rut depth propagation and to compare predicted rut depth with measured during service of the road. Four PPMs were analysed during this research based on a traffic flow or construction age. The pavement performance prediction models were applied to predict the increment of rutting for eleven road sections based on their bearing capacity properties.
