Description:
The report describes a field study of PM-2.5 and PM-10 (particulate matter with aerodynamic diameter less than 2.5 and 10 micrometers, respectively) emissions from a public paved road in Overland Park, Kansas, adjacent to a 200-acre construction site which will ultimately have 4 million square feet of office, retail, and service space. This study represents the first direct measurement of PM emissions from a roadway impacted by trackout mud/dirt from a construction site. Because the road surface loading visibly varied along its length, the roadway represents a nonuniformly emitting line source requiring adaptation of the exposure profiling method used in prior paved road studies. Multiple profiling towers were used to determine the dependence of PM emissions on distance from the access point where trackout originated. In addition to the trackout mud/dirt measurements, an ambient carbon particulate monitor provided data to distinguish the vehicle exhaust from resuspended road dust. Mud/dirt trackout from an active construction project is found to result in approximately 6 g of PM-10 and 0.2 g of PM-2.5 emissions for every vehicle passing over the affected roadway.
