Occurrence of tire-derived microplastics at a curvilinear road section

Abstract

Recently, microplastics originated from tire wear particle becomes a concern. This study surveyed occurrence of tire-derived mcroplastics (TMPs) on road by μATR-FTIR with a focus on road design. More specifically, samples were taken at different part of curvilinear section. The result shows the number of TMPs were higher at inner part of the curve, due to smaller rotating radius. In addition, the number of TMPs were found to be highest at the middle of the U-turn section, due to its smallest radius of curvature.
