What is the difference between a dust suppression and stabilisation binder?
The generation of dust on unsealed roads is caused by the loss of fine particles (typically those particles less than 0.075mm) from the loosening of the pavement materials at the surface and the disturbance of the wearing course caused by the action of traffic and climatic conditions, typically due to wind action. Dust suppressants tend to glue the fine particles together where as a stabilisation may or may not bind the smaller and larger particles together when applied in a stationary of mobile mixing plant. Dust suppressants are usually sprayed on the surface on a regular basis whereas stabilisation binders are mixed into the material and typically have a life exceeding 5 years.
