Comparison of Modern Concrete Pavement Performance Predictions, Thickness Requirements, and Sensitivity to Joint Spacing (Poster)

More than 25 design methods exist for jointed plain concrete pavements (JPCPs) --Many are based on the 1950s AASHO Road Test, including AASHTO 93 and CHAUSEE2 --The prominence of these methods created an expectation for JPCP thicknesses Modern JPCP design methods in North American are: --Founded in mechanistic (M) principles such as finite element analyses and; --Supplemented with empirical (E) calibration to field performance to increase the accuracy of key performance predictions of importance to owners and users, such as: Cracking in slabs, Faulting in joints, and International Roughness Index (IRI). This study extends prior work that compared AASHTO 93, Pavement ME, and StreetPave to illustrate the breadth of design variables considered and the sensitivity of required JPCP thickness to traffic magnitude, the use of dowels, concrete flexural strength, concrete modulus of elasticity, edge support, design reliability, and k-value
