AP42 13.2.4 Aggregate Handling And Storage Piles

Feb 01, 2006 When freshly processed aggregate is loaded onto a storage pile, the potential for dust emissions is at a maximum. Fines are easily disaggregated and released to the atmosphere upon exposure to air currents, either from aggregate transfer itself or from high winds. As the aggregate pile weathers, however, potential for dust emissions is greatly reduced.

The Life Cycle Energy Consumption and Emissions of Asphalt
