...Asphalt Emulsions For Cost-Effective Dust Control
PEP (Penetrating Emulsion Prime), DUSTAY, DUSTBUSTER, AEP-L. These are some of the names for SemMaterials economical dust palliative products, formulated to work with local materials and local conditions. How do they work? The water and emulsifying agent act as carriers for the tiny asphalt droplets to penetrate and fully coat the surface. The soapy emulsifier makes the water "wetter", to aid in the dispersion. As the emulsion cures, the water evaporates, leaving the asphalt to encapsulate the dust and protect the surface.
Environmentally Friendly Water Based Emulsions
Because the emulsions are water based, they are easy to handle. After the emulsion has cured, the asphalt waterproofs the surface, and doesn't run or wash off into fields or streams.
Lasting Results
The asphalt not only keeps the dust down, but actually upgrades gravel roads. The traffic load is an important factor on the durability, but our customers usually find the treatment lasts for the entire season. Typically, it will be applied in the spring, and not need re-treatment until the next spring. And then, often a single application at a lower shot rate will suffice. The application also prepares the surface for possible future asphalt treatments, such as chip seals, cold mix and hot mix.
