Modeling and testing of road surface aggregate wearing behaviour

The amount of urban dust and especially the particulate matter (PM) production is closely related to the wearing resistance of the aggregates on the road surface. In this research, the Aachen Polishing Machine (APM) was used to conduct wearing tests; the APM uses real vehicle tires. The obtained results were analysed with a rubber-road wearing model. Based on the spectral analysis of the texture, the wave length coinciding with the most wear of...
