• 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.
