5.13 It is estimated that in the second half of the 1980s the total consumption of aggregates in Hampshire was between six and seven million tonnes a year, although it has fallen by perhaps as much as 25 per cent since then. Less than half of this demand has been met by land-won sand and gravel. There are movements of sand and gravel across the County boundary, both into and out of the County, but exports are generally balanced by imports. The balance of demand, amounting to around 3.5 million tonnes a year in the late 1980s, is met by other sources of material, known collectively as alternative aggregate sources. This material mainly comprises marine-dredged sand and gravel and imported crushed rock, but it also includes secondary or substitute aggregate materials. These materials can be used for the same purposes as land-won sand and gravel, although crushed rock is mainly used in road construction, repair and maintenance.
