PREDICTING AGGREGATE PERFORMANCE OF THE IGNEOUS AND METAMORPHIC ROCKS, NORTHERN ONTARIO

A major field mapping and laboratory testing program was carried out to assess the potential for using a variety of igneous and metamorphic rocks on the Canadian Shield. The purpose was to identify a series of quarry sites along major highways to provide sources of aggregates for highway maintenance and construction. Most rock units had not been used before, and the assessment was designed to yield base-line data and information for predicting potential aggregate performance. Experience indicates that accurate field observations could predict the overall quality of the rock at 86% of the sample sites. The Micro-Deval Abrasion Test data, when used without any other data, was able to predict the overall quality in 64% of the test sites. The use of field observations with only the results of the Micro-Deval Abrasion test yielded 94% accuracy in predicting the physical quality of the rock unit.
