SPR-4914: Review of INDOT Standard Aggregate Gradation

The objective of this study is to assess the benefits or disadvantages of adopting AASHTO gradation classification (M 43) in Indiana. It is anticipated that this will potentially reduce confusion and cost for aggregate producers who operate in Indiana and neighboring states when the national standards (AASHTO) are followed. An added benefit in adopting AASHTO aggregate sizes could be an improvement in quality of concrete produced resulting from more optimized gradation. If found to be beneficial, the study aims to provide guidelines for the implementation of AASHTO standards.
