1993 Aashto Guide For Design Of Pavement Structures To Excel Upgrade Your BrowserThe new procedure, MnPCC-ME, is based on the AASHTO Mechanistic Empirical Pavement Design Guide (MEPDG) Version 1.1, but restricts the user to predetermined design input parameters. MnPCC-ME matches the MEPDG predicted performance at a fraction of the computation cost. In addition, MnPCC-ME provides alternative reliability analysis, which is based on a Monte Carlo simulation of pavement performance predictions based on typical variability in slab thickness and flexural strength for Minnesota pavements. The MnPCC-ME program requires virtually no run time and outputs a project report with the recommended design thickness for given performance criteria and reliability level for the specified reliability analysis. Although this tool was developed for Minnesota local conditions, the approach developed in the study can be adopted by other transportation agencies for their region and conditions.

The new procedure, MnPCC-ME, is based on the AASHTO MechanisticEmpirical P avement Design Guide (MEPDG) V ersion 1.1, but restricts the user to pr edetermined design input parameters. MnPCC-ME matches the MEPDG predicted perfor - mance at a fraction of the computation cost. The user is able to modify key design inputs for state and local pavement projects; the parameters include district climate les and trafc load spectra les (based on his - torical Minnesota DOT weigh-in-motion data). In addition, MnPCC-ME provides alternative reliability analysis, which is based on a Monte Carlo simulation of pavement performance predictions based on typical vari - ability in slab thickness and exural strength for Minnesota pavements. The MnPCC-ME program requires virtually no run time and outputs a project report with the recommended design thickness for given per - formance criteria and reliability level f or the specied reliability analy - sis. Although this tool was developed f or Minnesota local conditions, the approach developed in the study can be adopted by other transportation agencies for their region and conditions. 1993 Aashto Guide For Design Of Pavement Structures To Excel Update Its DesignThe Minnesota Department of Transportation (DOT) recently decided to update its design procedure for rigid pavements. The Minnesota DOT had previously used its RIGIDP A VE software as the basis for jointed plain concrete pavement (JPCP) design for projects in Min - nesota. This software used a design procedure based on the AASHT O 1993 procedure for rigid pavements, informally referred to here as AASHTO93 ( 1 ). As noted by the pavement research community and observed empirically in the longevity of the JPCP at the Min - nesota Road Research Project (MnROAD)AASHTO93 is a purely empirical and generally conservative design procedure ( 2, 3 ). The Minnesota DOT also desired a rigid companion to its estab- lished exible pavement design procedure, MnP A VE ( 4 ). MnP A VE has been widely adopted in Minnesota and provides users with a contemporary mechanisticempirical (M-E) design for exible pa vements, whereas RIGIDP A VE does not offer the same for rigid pavements. This difference in state pavement design tools compli - cated alternative bids for a given paving project.
