The strongest dust control palliative we offer. A blend of lignin and asphalt creates a paved road appearance. Eliminates the need for watering for the duration of the season. Requirements for preparation: Surface needs to be bladed, free of excess loose gravel, and pre-watered with a moisture content 3 to 4 inches deep. If treated area is a roadway, a 3 percent crown is recommended to keep water from pooling in the center of the road.
