  • The Environmental Impact of Asphalt Plants

    Asphalt plants, or more accurately asphalt pavement mixing facilities, are industrial operations that mix liquid asphalt binder (also called asphalt cement) with crushed rock, gravel, and sand (collectively called ag gregates) to make pavement Asphalt binder, the glue that binds the aggregates together, is one of manyThis process has many significant environmental impacts [1] Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath Not only does this lead to a loss of existing animal wildlife, it3 The Environmental Impacts of Aggregate Extractionmental impacts from quarrying carbonate rocks in karst Documentation of the relationships between carbonate rock quarries and environmental problems in karst has existed for nearly fi fty years, but is scarce There are numerous articles in the literature thatPotential Environmental Impacts of Quarrying Stone in
