About the research

The objective of the study wass to evaluate the effectiveness of two dust control additives that have been used but subject to limited systematic studies. The two suppressants were ground asphalt shingles and soapstock (a soybean oil byproduct). These materials were compared with untreated sections, as well as lignin and calcium chloride that are currently widely used as dust palliatives
