CalME Change Management
CalME is expected to be updated from time to time. The following are some of the reasons that will trigger an update:
•To fix software bugs,
•To add new features: such as supporting new materials, new pavement structure types,
•To update models, either due to better calibration with updated PMS data, or due to improvements in the models
Each major CalME update requires a decision document that outlines the reason for the update, description of changes, and expected difference in design (if applicable).
A list of the major changes since the release of CalME v3 and the associated decision documents are shown in the following table:

CalME-V3-DD001 |
3/3/2020 |
The CalME v3 version released in January 2019 used materials representing 5th percentile performance to account for between project variability. This was used as an interim solution for between projects variability while CalME was being calibrated with field performance data from the PMS. CalME models have now been calibrated with field performance data. The materials as well as calibration factors have been updated to more explicitly account for the 95% design reliability. |

This version was the last version before being upgraded to v3DD002. It includes several minor bug fixes on the user interface. |

CalME-V3-DD002 |
12/1/2022 |
This release includes addition of recycled materials in the standard materials library, updated damage models for cement stabilized materials, and updated calibration for overlay designs.
There are several user interface changes as well: •The enforcement of design rules are delayed until user tries to start M-E simulation. •The ability to generate initial guess design is added for new construction designs. This can now be done without running empirical designs. •In keeping with the cracking plot, the result plot shows failure probability for rutting in stead of average rut depth. •A bug/issue reporting system has been added. •This online help has been rewritten to match the new version. |
