REPORT OF AGGREGATES AND WASTE MATERIALS WORKING GROUP
This report is concerned with five items: (A) The derivation of technical coefficients (given as an appendix) for estimating the consumption of aggregates by various construction sectors. A table gives estimates of the annual production of different types of aggregate and the amount used for different purposes; (B) determining the consequences of exploiting alternative aggregates to sand and gravel. It is concluded that crushed rock can be used in concrete, light-weight aggregates may also be used if design criteria are more stringent, lower-grade and waste materials may be used as road fill and in sub-bases, and that an increase in the cost of aggregate has more effect on the overall cost of roads than of buildings; (C) reviewing test criteria in British Standards and other specifications, which in the light of present knowledge, are not considered to be unduly restrictive; (D) surveying waste materials. The current production utilization and amount of stockpiled materials are summarized in a table. The major waste materials are discussed individually and a map shows their distribution. Details are given of an analysis of the social cost of using colliery spoil in road construction; (E) investigation of the part played by the cost of transport on the choice of aggregates. Various forms of transport are discussed including road, rail, water, conveyor belt and pipe-line systems. The report also includes details of a number of recommendations that are made for further research.
