ABSTRACT
Aggregates used in Norway are mainly derived from Quaternary glaciofluvial sand and gravel deposits and crushed hard rock. Gravel and Hard Rock Aggregate Databases are computerised databases which provide an inventory of all known deposits in the country along with information on their volume and quality. The construction industry and the State Road Authority are the most important consumers of sand, gravel and hard rock aggregate in Norway. Increasing environmental awareness limits industrial activity with the vicinity of housing and recreational areas. The Gravel and Hard Rock Aggregate Databases contain a range of data which allows different user groups to extract information for their separate purposes. Sand, gravel and crushed hard rock aggregates are Norway's most important construction materials, with an annual market value of approximately NOK 2300 million.
