GEOLOGICAL CONSIDERATIONS AFFECTING AGGREGATE SPECIFICATIONS
The development and application of testing procedures to assess the properties of aggregate resources have been studied for most of the 20th Century. Even so, the resulting testing procedures do not always ensure that the aggregate will perform well in service. The influence of geologic factors on rock properties and their suitability for use as aggregate has been recognized, but geologic factors have not received the same emphasis in the literature as engineering aspects. This paper describes the geologic factors that affect rock properties, and encourages the broader use of geology in the development of empirical tests, establishment of specification limits based upon such tests, and interpretation of the results of those tests for selection of aggregates for use under specific conditions of service.
