Quantification of Influence Factors in the Studded Tire Wear Using the Prall Device

Studded tire wear is widely considered to be a critical aspect that conditions the ride quality in cold regions. This research provides a comparative analysis of the influence of certain factors on pavement wear caused by studded tires. Abrasion resistance measurements were conducted on aggregates and asphalt specimens, using the Nordic Ball Mill apparatus and the Prall apparatus, respectively. This approach ensures an understanding of the interaction between these variables and the resultant wear response of the asphalt mixture. Tests relied on three different types of asphalt mixtures (ESG, dense-graded asphalt; EG, coarse-graded asphalt; and SMA, stone matrix asphalt), different percentages of reclaimed asphalt pavement (0%, 10%, and 20%), and different aggregate hardness. Image analysis methodology was used to assess the coarse-sectional area of the sample covered by coarse aggregates. The results showcased that harder coarse aggregates were less prone to wear. Comparisons indicate that the SMA10 yields higher abrasion resistance than the remaining mixtures used in this study. The percentage of the cross-sectional area covered by coarse aggregate influences the mixture abrasion value.
