Many unpaved roads require dust control measures throughout the course of the year. However, magnesium chloride and calcium chloride dust control agents have been known to have some significant drawbacks. Wild animals that are in search of minerals tend to be drawn to chloride-treated roads and the runoff pollutes local watersheds. When you also consider that chloride-based agents require multiple... read more »
The use of a prime coat is common in many bituminous pavement projects. A prime coat is meant to protect the subgrade road bed from the effects of water, excess moisture and weathering. Any significant moisture in the subgrade affects its strength and integrity. This can lead directly to early degradation of the road surface, or even outright failure. When... read more »
Lignosulfonates have been used as a dust control measure on unpaved roads for many years. They are essentially a byproduct from other industries; for example, they are a common waste product in wood pulp processing. While these industries see the sale of lignosulfonates as a cost-effective maneuver, they do have some significant disadvantages when it comes to long-term dust control... read more »

Synthetic polymers such as polyvinyl acrylic and acetate polymers are byproducts from the pain and adhesive industries. They are sold as a road maintenance and dust control compounds for unpaved roads, to improve profit margins and reduce disposal costs. Synthetic polymers have several notable drawbacks. On a chemical level the polymer chains are rather large and tend to bind more... read more »
Lignosulfonates, more commonly known in dust control as lignin, is a byproduct of the wood pulp processing. In order to increase profit margins, the wood pulp industry commonly sells lignin as a dust control product. Lignosulfonates come with some considerable drawbacks. They are chemically corrosive by nature. Over time this corrosive effect can weaken welds and damage storage tanks. They... read more »
Excess dust on unpaved roads can lead to several hazards. The dust poses a threat to respiratory health and affects road safety. If unpaved roads are left untreated it can also lead to bigger problems like road deterioration, and excess soil runoff. Many companies that offer dust control services use calcium and magnesium chloride based sprays. These agents can have... read more »
