Dust Control For Roads: 5 Best Methods

Let’s take a look at five of the best solutions for dust control out on the road.

Why Is Road Dust Control Important?

Dust suppression methods have been used for decades in the U.S. Recently, government agencies have tightened regulations across service industries, designed to advance the technology used to combat airborne dust particles.

Of course, there are many community and environmental factors to consider when it comes to dust suppression systems. Here are reasons why dust suppression is necessary.

Health And Safety Purposes

When dust particles are inhaled, it can result in serious health issues like lung diseases and respiratory problems. Fine particle matter like silica dust, for example, can contribute to silicosis and even lung cancer. You can protect the health and safety of workers and nearby residents with the use of dust suppression.

Protect The Environment

Environmental degradation can occur when dust settles in soil, water, and vegetation. It’s no secret that dust can contribute to air pollution, as well.

Efficiency

Dust may interfere with machinery and equipment currently in use. This can lead to both increased downtime and maintenance costs. Effective dust suppression systems can undoubtedly improve the efficiency of the equipment on-site.

Keep The Community Clean

Dust from roadways can have negative impacts on the surrounding communities. Dust suppression systems can improve community relations while more importantly keeping the area safe.

Best Road Dust Control Solutions

Here are five of the best dust control solutions detailed below.

Dust Control Polymers

A layer of polymers can help fill gaps on road surfaces, forming a tough surface that keeps it stable. They are mixed with water and ultimately spread on top of the road. This results in a thin layer that adheres to the particles, preventing more dust from being lifted and airborne.

Polymers are typically quite effective on highly trafficked roads. These products are weather-proof, meaning they will make an impact no matter the conditions. The only downside is the cost as polymers are a more expensive option compared to water suppression.

Chemical Dust Suppressants

Chemical dust suppressant options include calcium chloride or magnesium chloride. Both of these agents work by pulling moisture out of the air and onto the road. These chemicals are hygroscopic, binding with the road surface to keep dust particles damp even when the outdoor conditions are quite dry.

Chemical treatments last longer than water suppression, typically enduring weeks or even months of traffic. However, these chemicals are potent, so they need to be handled with care, at all times. The chemicals are especially beneficial when used in remote or industrial locations.

Water Dust Suppression

Water suppression is the easiest and most efficient method of dust control. Water applied to unpaved roads binds dust particles, preventing them from getting airborne. This method works best for controlling dust accumulation on a temporary basis, especially prior to rainy seasons.

Fixed sprinkler systems, as well as water trucks and sprays are responsible for applying this solution to the roadways. Water suppression needs to be applied regularly for the best results possible.

Gravel And Aggregate Surfacing

Crush stone or gravel when placed on road surfaces will increase weight and texture in order to prevent dust buildup. This method essentially acts as a shock absorber between loose soil and the weight of a vehicle.

While this is an inexpensive option overall, it will require regular refilling since gravel will shift over time. This method is best for areas that receive only some traffic and need minimal dust control.

Dust Suppression System Services

Dust suppression refers to the techniques and methods applied to ultimately control and reduce airborne dust particles in several different environments. There are many common creators of airborne dust, such as quarries and mines, construction sites, both paved and unpaved roads, material handling facilities, and more.

Particulate matter from the aforementioned sources can become fugitive when they combine with either wind or mechanical force. Unfortunately, these particles pose substantial health risks to workers and any individuals nearby. This can also wear equipment down and cause environmental damage.

Dust suppression systems mix water, chemicals, and various other materials to prevent dust from entering the air. These systems can also trap and eradicate dust once it is in the air. The overall goal is to keep individuals and the environment clean and safe.
