As a result of meetings with producers, a committee of Highway Department engineers recommended that a study be made of various type of aggregates from statewide sources; the objective being to arrive at a standard of evaluating unit weight of aggregates of various but commonly recognized characteristics. It was further desired that a factor be determined which could be applied to a given aggregate for computing its unit weight with reasonable accuracy; taking cognizance of specific gravities and densities as influenced by particle shapes and gradation.
