    Aggregate is used in construction to create stable foundations for things like roads and railroad tracks Aggregate is also used to make concrete and asphalt For this reason, asphalt and concrete plants are often built next to quarries Asphalt is an oily substance that is mixed with aggregateMost old pits and quarries are not being properly rehabilitated As noted in one study “less than half of the land disturbed for aggregate production between 1992 and 2001 has actually been rehabilitated” The province classifies pits and quarries as “interim uses of the land” and requires 100% rehabilitation of pits and quarries3 The Environmental Impacts of Aggregate Extractionthe 2007/2008 recession, total aggregate production has fallen to its present levels from a high of nearly three billion annual tons in 2006 In 2012, the national average selling price of construction aggregate was approximately $890 per ton FOB (freight on board loaded on trucks at the mine):Valuation of Aggregate Operations for Banking Purposes
