Sustainable pavement applications utilizing quarry by-products and recycled/nontraditional aggregate materials
Quarry By-products (QB), usually less than 0.25 in. (6 mm) in size, are the residual deposits from the production of required grades of aggregates and are often stockpiled in excess quantities at the quarries. More than 175 million US tons of QB are produced every year from the 3,000 operating …
