WinJULEA This is a demo version of the software, which  is under development for the AASHTO 2002 design guide. The copy posted here is the one available on the NHI course 131064 CD (FHWA, April 2002). No support or manual is available.

CHEVPC This is a PC version of the Fortran program of the Chevron Elastic Layer Analysis program.

WESLEA  Waterways Engineering Station Elastic Layer Analysis Pavement Suite.

AASHTO_EALF.xls An Excel Tool developed by Dr. Bayomy for the AASHTO Equivalent Axle Load Factors for Flexible and Rigid pavements.

AASHTO_Rigid.xls An Excel Tool developed by the FHWA Long-Term Pavement Performance (LTPP) program to supplement the AASHTO pavement rigid design system. For help on the use of this Excel tool, you can download its instruction text file.

PCAPAV For damage analysis of PCC pavements based on the PCA design method. This DOS-based program was released in 1990. Download Example File.
You can obtain information on how to obtain your own copy from the American Concrete Pavement Association (ACPA) web site.

DARWin 2.0 (Pavement Design, Analysis and Rehabilitation for Windows). 
This is a proprietary AASHTOWARE computer software product. The UI have a license for this software. It is available at the Highway Design Lab (BEL 117). Campus students are required to use it for their design activities. Video students are also encouraged to use it if they have an access to it, but not required. To obtain your copy, contact AASHTO.

WINFLEX 2000  A mechanistic-empirical overlay design system for flexible pavements. This software is developed by Dr. Fouad Bayomy under research contracts with Idaho transportation Department (ITD) at the UI Center for Transportation Infrastructure (CTI) of the National Institute for Advanced Transportation Technology (NIATT).
