Dust generation and suppression issues in gravel roads Introduction: While travelling on gravel roads dust can be seen. Dust on gravel roads may be generated due to various reasons like movement of heavy loads or by heavy wind. This dust is emitted by exhaust of vehicle, wind or by the movement of vehicle. It has been seen that wind erosion does not happen unless speed of wind is greater than 25-35 kmph at 2m height (Karin Edvardsson, April 2010), this dust is mainly generated by vehicle movement
