Tire Road Wear Particles (TRWP) from Measurements to Stakes
摘要
This paper presents a new methodology to evaluate the Emission Factors for PM10 and PM2.5 from tire wear using an on-road driving collecting device to capture the Tire Road Wear Particles (TRWP) directly at the source. Special attention was paid to ensure a maximal reduction of the usual biases associated to this kind of approach: the test track was systematically cleaned prior to all the tests, only one vehicle was allowed during the tests, the design of the collector was made to maximize the collection of TRWP of the tested tire. The results show emission factor values significantly lower compared to those commonly reported in the literature. The discrepancy calls for further tests to confirm the results.
