SECTION II SUMMARY The crushed stone industry converts naturally occurring stone deposits into a crushed stone form for use in the construction industry (81% of the output) Crushed stone, as interpreted in this study, includes: traprock, calcareous marl, shell marble, mica schist, slate, and other miscellaneous stone excluding granite, limestone, dolomite, sandstone, quartz, and quartzite The quality of crushed stone aggregates influences the durability and performance of pavement and concrete as they are the dominant component in the mix H TES analysis for crushed stone aggregate quarry site selection: the case of limestone terrain around HarerDire Dawa towns, Eastern Ethiopia SpringerLinkTES analysis for crushed stone aggregate quarry site The paper presents the results of hygienic assessment of metallurgic slag crushed stone to be added to natural materials in highway building The re program has included the measurement of content of watersoluble forms of metals, the evaluation of the acute toxicity of waste after oral administration to mice and rats, the study of the toxicity of waste by biotesting and the activity of natural radionuclides[Hygienic assessment of metallurgical slag crushed
