• Abstract:
  A thickness design method for jointed fiber reinforced concrete pavements is developed by modifying the current PCA "Thickness Design for Concrete Highway and Street Pavements" based on the fact that the fatigue properties of fiber reinforced concrete (FRC) are different from those assumed in the design procedure for conventional concrete pavements. To recognize the unique fatigue properties of FRC, new endurance limit and fatigue S-N curves (Fatigue Stress Ratio versus Number of Load Repetitions) must be established from test data of the FRC. It is impractical or impossible to develop a uniform endurance limit and S-N function for all kinds of FRC because the fatigue properties of FRC vary significantly with fiber type, fiber content, aspect ratio, bonding and anchorage feature, and mix design. However, an evaluation of steel fiber reinforced concrete pavements in field application (Haines Avenue in Rapid City, South Dakota) demonstrates how the fatigue properties of a specific FRC are determined and used in the modified thickness design method. Both the theoretical analysis and the field inspection indicate that the steel fiber reinforced concrete pavement is very strong against transverse fatigue cracking. On the other hand, the deflection at joints becomes the major concern of FRC pavement design because of reduced thickness and increased flexibility. The PCA erosion criterion, which is derived from critical deflection and subbase pressure near joints, provides a useful control over erosion and other distresses in association with slab joints.
