The best methods of haul road dust suppression

Construction and building teams need to be able to manage soil disturbance where they are working. Loose soil can result in increased sediment in nearby lakes and rivers, cause problems with air pollution and visibility, and even affect the health of nearby residents. Large areas of Australia are affected by loose soil and dust disturbance during house-building, construction work and mining and resources production. One of the most vulnerable areas of dust movement is haul roads, which are used by larger vehicles to access the site. Site owners and managers are responsible for this environmental disturbance, and need to take steps on haul road dust suppression as soon as possible.

How dust is disturbed by heavy vehicles

In the past, access roads to construction or mining sites were not paved, or even covered with gravel, meaning the heavy vehicles travelled directly over soil that had already been disturbed by movement. Recent awareness of the environmental impact of haul roads, including air pollution and soil erosion, has meant that there is now more pressure to manage these roads more effectively, using a combination of road planning, stabilisation on the path, and road dust suppression products designed to prevent the soil from being eroded. All of these steps can help a construction team to manage dust more effectively at the site.

Transforming haul roads

The first step in managing dust from haul roads is to stabilise the ground and the road. Many sites choose to use lower gradients in the road, meaning that lorries and haulage vehicles do not have to travel up the road in higher gear, and there is less friction in the road. Laying pavers in the road can also help to prevent the wheels from disturbing soil, helping to prevent dust being lifted into the air. Transforming the road itself can help to prevent soil erosion.

Using stabilising products

In addition to controlling haul road dust through the careful planning of roads, it is also possible to add chemicals and Road Stabilisation Applications to the soil in order to prevent it from loosening. Watering the roads is one effective way of preventing soil erosion, and there are also chemicals that can help to prevent soil from being disturbed in this manner. This can help to ensure that there is little air pollution and soil erosion from haul roads.
