readers used either popup filter bags, or a filter can with keeny tubes to prevent dust while filling from the bulk tankers. Front and rear conveyor chain seals respond to the inload pressure to further seal the hopper.

Dust control while spreading is primarily controlled by heavy duty dust curtains to control dust splash back and wind drift. In more dust sensitive situations, a spray system is used to suppress fugitive dust.

In a presentation by Tim Ziegler of the Center for Dirt and Gravel Road Studies at Penn State given to the Marcellus Center for Outreach and Research¹, pointed to additional advantages of FDR. First, the new base is dust free while awaiting paving, and second, the new road is only inches higher than the old base. By not adding height, the new road does not increase the runoff impoundment from heavy rains.
