The contractor will obtain the literature and software necessary to evaluate the NCHRP 1-37A rigid pavement performance models, known as the 2002 Mechanistic-Empirical Pavement Design Guide. The contractor will assure the reasonableness of the performance models for cracks, faults, spalls, punch-outs, and international roughness index (IRI.) Measured IRI will be tested against computed for the given distress measures and pavement attributes. A sensitivity analysis will be conducted by varying all related inputs at once. The software and design procedure will be demonstrated and tested at a State DOT. |
