Uses of Aggregates in Construction
Aggregates can be used for many different projects within the construction sector. In concrete, an aggregate is used for its economy factor, to reduce any cracks and most importantly to provide strength to the structure. In roads and railway ballast, it is used to help distribute the load and assist in ground water running off the road.
Recycled aggregate is produced by crushing concrete, and sometimes asphalt, to reclaim the aggregate. Recycled aggregate can be used for many purposes. The primary market is road base. For information on recycling asphalt pavement into new asphalt pavement. See Asphalt Pavement Recycling.
