Fugitive dust and roadbed degradation are always serious concerns associated with maintaining an unpaved surface. Sand and soil particles can often be released from an unpaved road by passing vehicles, which can lead to serious safety concerns, visibility issues and may contribute to respiratory health problems in the local populations. At the same unpaved roads that experience a high traffic... read more »

Unpaved roadbeds are typically composed of a combination of gravel, sand, aggregate stone, local soil, and other small particles. Throughout the course of a year, weather and seasonal changes can gradually start to affect the relationship between these various components. Rainfall, dry conditions, the changes of seasons, and the freeze-thaw effect can cause an unpaved roadbed to develop potholes, ruts,... read more »

Dust control and maintenance of unpaved roads is a significant concern in many locations throughout the United States (and even Hawaii and Alaska) and various locations around the globe including parts of South America, Africa, and Europe. When fugitive dust particles are released into the air they can pose safety hazards, impair visibility, and potentially cause respiratory distress. Some agencies,... read more »

When calcium chloride and magnesium chloride based dust control agents first came into use, they were perceived as a cost-effective alternative to water truck delivery for controlling dust on unpaved roads. After all, water trucks required extensive man hours, available water resources, and often multiple applications each week during excessively dry conditions. As time went by, these chloride-based dust control... read more »
