Environment/ConditionsNorth America’s aggregate producers (makers of crushed stone, gravel, and sand) supply more than 2 billion tons (~$18B) of vital material per year to help drive our entire construction industry – including roads, bridges, residential and commercial buildings and many other civil and environmental applications. According to the United States NSSGA (National Stone, Sand and Gravel Association), every $1M produced creates 19.5 jobs, and every dollar of output contributes $1.58 to the U.S. economy.Today’s aggregate producers use the latest technology to improve quality, efficiency, and output while working to control dust and noise, all the while focusing on the safety and health of employees and the surrounding communities.Solutions:Our customers rely on PTI’s wide range of products to increase reliability and performance in the aggregate industry.
