Phase III Iowa Pore Index: Morphometric Properties of Aggregates

This study aims to develop a new specification for fine aggregate quality. This specification will be based on more characterizing the quality of fine aggregates by applying chemical and pore system tests to them, similar to what is done with coarse aggregate, as well as measuring the sizes and shapes of their particles more quantitatively with new technology, the Camsizer P4. All fine aggregate sources currently approved by the Iowa DOT will be analyzed in this new method. In addition, this study will assess the extent to which manufactured sand has equivalent quality to natural sand as well as analyze coarse aggregates using the Camsizer P4.
