PCASE

Software

PCASE software is considered public information and is therefore free to all users.

PCASE software implements Department of Defense Unified Facility Criteria for the design and evaluation of airfields and roadways including:

  • Rigid, Flexible, Overlay, Aggregate, or Mat surfaces
  • Subsurface Drainage
  • Seasonal Variations
  • Evaluation Equipment Support Software
    • Dynamic Cone Penetrometer (DCP)
    • Non-Destructive Testing (NDT) using Falling Weight Deflectometer (FWD) data
  • Evaluation Analysis Software using empirical or layered elastic methodology
    • Back-calculate Modulus values based on testing data
    • Calculate allowable loads and passes based on mission traffic
    • Calculate Pavement Classification Numbers (PCN) based on mission traffic
    • Calculate overlays required to support mission traffic

PCASE 7.0 is the newest version of PCASE. It has undergone significant testing, has passed the Risk Management Framework Assessment process, and is approved for use on USACE IT systems. As with any new software release, we anticipate some minor bugs. If you encounter any issues please contact the PCASE Program Manager, George VanSteenburg at george.w.vansteenburg@usace.army.mil, 402-326-5646 or provide comments using the Comment Sheet (available for download at the link below). All 2021 PCASE training will be conducted with version 7.0. See the training page for dates.

Other Software Tools

  • Standard Detail Drawings - Standard Detail Drawings - CAD files for standard details used in the design of transportation systems from 3-260-01, 3-260-02, 3-270-1, 3-250-11, 3-250-01 and 3-230-06. The figure numbers on these drawings correspond to the old Design Guide (DG 1110-3-204).
  • PAVER™ - Pavement Maintenance Management System
  • MODBERG - Tool for calculating depth of frost penetration. Note that MODBERG is not currently certified for use on Department of Defense information systems, but still implements current criteria. The application has not been updated since 2006, so you may encounter issues with installing it on a 64-bit operating system and when installed it must be run in compatibility mode.
  • TRACK 3.1 - Railroad Track Evaluation Program. Note that TRACK is not currently certified for use on Department of Defense information systems, but still implements current criteria. It has not been updated since 2006 and must be run in compatibility mode.

Approval to Operate (ATO): Current federal regulations require all major applications and general support systems to be certified as being compliant with information technology security requirements so that information resources and data are protected adequately. PCASE has been approved for use by the Services through their respective approval processes:

Army and US Army Corps of Engineers: PCASE is approved for use through the Risk Management Framework Assess Only Process. Approval information is available in eMASS
