Planned 2018 Enhancements

August 01, 2017

The Pavement ME Design Task Force authorized the following enhancements for delivery in 2018 :

Recalibration of the Flexible and Semi-Rigid Pavements Transfer Functions

The flexible and semi-rigid pavement transfer functions have not been recalibrated since the software was taken over by AASHTO in 2010. In FY2018, the flexible and semi-rigid pavement transfer functions will be recalibrated which will be completed by the end of this calendar year. As a result, a mid-year release of the software is planned for early January 2018.

Capability to Reset Performance Threshold Values within a Design Period

The user will be able to reset selected performance and distress values within a design period, so different pavement preservations strategies can be considered. Many agencies have requested this feature be added to the software. It will be available for the FY2018 release in July 2018.

Customization of Reports

Users will be able to identify specific distresses for determining the reliability of a design strategy for both new and rehabilitated pavement designs. Other customization features will also be integrated into the interface of the software, giving users more flexibility.

Availability of MERRA Climate Data

The Modern Era Retrospective-Analysis for Research and Applications (MERRA) climate data will be available for users in FY2018. The advantage of this enhancement is that it gives the international users access to climate data anywhere in the world.

Continuing the Move toward a New Web Technology Application

The Pavement ME Design Task Force, along with input from the AASHTOWare Technical and Application Architecture Task Force (T&AA), is continuing development of a new web technology application for Pavement ME Design. In FY2016, the initial phase of the web technology application was created as a “minimally viable product,” containing only the minimum inputs required to run a single Pavement ME Design analysis for new Jointed Plain Concrete Pavement (JPCP). The result of this effort was Pavement ME Design v3.0 (web technology application). The next phase will be implemented in FY2018.
