Up until the mid-late 1970s, ash (aka 'clinker' or 'cinders') was routinely used as a bedding material for all sorts of pavings, but the demise of the coal-fired power stations, along with the concurrent reduction in other coal-powered industries such as textiles (up here in the north), steel-making, etc., saw the volume of available ash reduced and it has now been …
Typically, aggregate used in HMA production will have a bulk specific gravity between about 2.400 and 3.000 with 2.700 being fairly typical of limestone. Bulk SSD specific gravities can be on the order of 0.050 to 0.100 higher than bulk oven dry specific gravities, while apparent specific gravities can be 0.050 to 0.100 higher still.
