Abstract

Representative soil was evenly applied to an 800-m section of road surface. The test area was of sufficient length to allow for measurement at constant speeds of up to 72 km hr−1. SCAMPER and TRAKER™ mobile measurement vehicles made repeated test runs while an instrumented tower measured upwind-downwind horizontal PM10 flux. AP-42 methods were used to collect silt samples and calculate PM10 emission factors. Both silt loadings and vehicle speeds were varied during the experiment. Street sweeping the as-found roadway showed an initial rise in PM10 emission rates. Both TRAKER and SCAMPER measured rapid decay of PM10 emission rates after depositing soil. Both the tower flux and AP-42 silt loading measurements were consistent with the mobile methods. Decaying particle suspension rates suggest emission rates are a function of both vehicle speed and silt loading. Mobile methods allow a cost-effective method of rapidly measuring PM10 emissions from roadways.
