Abstract Paramount to sound aggregate resource management is an awareness of what resources exist. For the past six years, New Brunswick has been conducting granular aggregate resource inventories in and around urban centres as a means of documenting, both qualitatively and quantitatively, these resources.These aggregate studies require extensive ground truthing due to the often small nature of the surficial features as well as extensive foliage. Approximately 35% of the province's land mass has been mapped at a 1:50,000 scale as part of this on-going program. Reports are published annually and include data on size analysis, lithology soundness, abrasion and absorption.Aggregate deposits in New Brunswick frequently reflect the local bedrock lithology and, whereas much of New Brunswick is underlain by soft, friable sandstone of Pennsylvanian age, it is necessary to transport aggregate for higher-specification use considerable distances. Alternatively, the construction industry must turn to crushed stone as a source of asphaltic or concrete aggregate.Over 40% of New Brunswick's land mass is owned by the Crown, and aggregate resources are managed under the Quarriable Substances Act. Under this legislation, permit applications are reviewed by a Land Management Advisory Committee which consists of representatives from the various government departments involved.
