• Abstract:
  Fugitive dust emanating from vehicle traffic on unpaved roads and runways can have significant impacts on safety, health, quality of life, and the cost ; of maintenance. Managing dust provides a means of reducing these impacts. Shearing forces created at the interface between the surface and vehicle ; tires produce dust on unpaved surfaces. The dust produced becomes airborne as a result of turbulence created by moving vehicles. Once airborne, ; different monitoring techniques can be used to assess the amount of fugitive dust produced and to measure the effectiveness of dust management ; strategies. Communities can manage dust by properly constructing and maintaining the unpaved surface, reducing vehicle speed on roads, and with the ; proper use of dust palliatives. The proper gradation of aggregate, the right profile, and good drainage are all necessary for reducing fugitive dust from ; unpaved roads and runways. Moreover, reducing vehicle speed on unpaved roads can dramatically reduce the amount of fugitive dust and result in ; longer periods between maintenance events. Several different types of palliatives are available for both managing dust on unpaved roads and runways. ; The choice of palliative is dependent on aggregate gradation, traffic amounts, climate, and location (remote or accessible).
