  • Dust Suppression With Gravelpave2

    Use of Gravelpave2 for pavement surfaces to restrict dust is a very viable suggestion, provided careful selection of the fine gravel fill is followed. Dust from gravel surfaces is created when vehicles pass over the surface - greater speed = greater dust and higher into air. Most gravel surfaces will have a wide range of particle sizes - from 1" to <200 screen (clay and silt sizes) or "dust". ...
