PRODUCTION OF CRUSHEDSTONE AGGREGATE In operating a quarry and crushing plant, the drilling pattern, the amount of explosives, the size shovel or loader used to load the stone, and the size of the primary crusher should be coordinated to assure that all stone from the quarry can be economically utilized. CHAPTER 14. AGGREGATE PRODUCTION
(1) Composition. Provide coarse aggregate that is crushed or uncrushed gravel, chat, or crushed stone. (Consider limestone, calcite cemented sandstone, rhyolite, quartzite, basalt and granite as crushed stone). When using quartzite, include supplementary cementitious materials to prevent ASR. Mixtures utilizing quartzite must
