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

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
POC is Mr. George VanSteenburg, George.W.VanSteenburg@usace.army.mil

Air Force: PCASE is on the Approved Software list
POC is Mr. Cecil (Lanar) Hastings, cecil.hastings@us.af.mil

Navy: PCASE is in the NAVY Approved Software portfolio
POC is Mr. Marshall Davis, marshall.b.davis@navy.mil

PCASE 2.09.08 is the current version of PCASE 2.0. It has been in use for over 15 years and updated periodically, but will no longer be supported after December 2021.

**New** PCASE 7.0 Release Candidate 6.0 is the newest version of PCASE. This release candidate is stable, has undergone significant testing, has passed the Risk Management Framework Assessment process, and is approved for use on USACE IT systems, but is still going through additional testing to ensure all computations are correct. We are posting PCASE 7.0 to afford users the opportunity to review and provide comments using the Comment Sheet (available for download at the link below).

Download the PCASE 7.0 install file at the link below and install (requires administrator rights). It may be installed on the same computer with PCASE 2.09.08. Both versions operate independently.

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.
