ABSTRACT
Access to allow orderly development and rehabilitation of lands endowed with construction aggregates needed for building and engineering construction has become an important concern in many regions of Canada. Shipments of all aggregates combined, including in detail, natural gravel, sand and crushed gravel, and crushed stone and miscellaneous stone, are based on quantities reported by operators of sand and gravel pits, dredges or quarries. The value of Canadian shipments of all construction aggregates combined was $1.2 billion in 1993, based on final statistics, or $972 million, in 1986 dollars adjusted for inflation. Shipments of sand and gravel amount to about 250 million tonnes per year, or about 73% of the total volume of all construction aggregates shipped, based on 1991-1993 data inclusive. Expenditures for building and engineering construction influence to a substantial degree demand for aggregates. The trends from 1974 to 1993 in average real unit values of sand and gravel, on a regional basis, have been relatively flat.
