3 The Environmental Impacts of Aggregate Extraction

As noted in one study “less than half of the land disturbed for aggregate production between 1992 and 2001 has actually been rehabilitated” [2] The province classifies pits and quarries as “interim uses of the land” and requires 100% rehabilitation of pits and quarriesMar 21, 2012 Domestic production data for crushed stone and construction sand and gravel are derived by the USGS from voluntary surveys of US producers In 2010, 13,600 aggregates The Nation’s Top 25 Construction Aggregates Producers Marine aggregates play an important role in replenishing beaches and protecting coastlines from erosion Satellite navigation may be used to position vessels precisely within licensed dredging areas Vessels trail a pipe along the marine floor at speeds approaching 15 knots and use powerful suction pumps to draw sand and gravel into the cargo Extraction of Aggregates Process CEMEX USA CEMEXFeb 05, 2018 Figure 1 shows per capita aggregate production for Australia, Canada, China, the European Union, and the United States Production is strongly related to population, and there is a huge difference in populations among these areas and each country’s aggregate production To normalise the graph, I plotted per capita aggregate productionGlobal aggregates production: 19982017 – Quarryof aggregate: stone, sand,and fines Depending on what the material is to be used for, the ideal blend of these three groups varies greatly For example, good surface material for a gravel road would need more material passing a #200 sieve than a good base materialSection III: Surface Gravel EPA
