Optimizing Mississippi Aggregates for Concrete Bridge Decks, State Study 231
This report addresses particle size distribution of material included in various maximum nominal size aggregates. This particle size distribution requires additional processing such as screening, separating, and recombining to meet AASHTO M 43 or the Mississippi Department of Transportations particle size distribution requirements. Specifiers of concrete mixtures have utilized additional requirements on aggregates by placing upper and lower limits on combined percent retained on individual sieves. MDOT has recently utilized this concept by introducing similar limits on aggregate gradations used in concrete for bridge decks. This research project investigates the workability and shrinkage performance of concrete containing aggregate gradations not meeting these requirements and compares this performance to concrete containing aggregate gradations meeting MDOTs requirements for bridge decks.
