Crushed stone screenings are the finer fraction of stone products and normally contain particles 4-5 mm 0.15-0.19 in size or smaller. As natural sand sources are being depleted, the demand for this manufactured sand will increase. Two advantages of stone screenings for highway construction are their uniform grading and crushed faces.
