Abstract:

AASHTO M 43 “Standard Specification for Sizes of Aggregate for Road and Bridge Construction”

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 Transportation’s 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 MDOT’s requirements for bridge decks.
