Stop manual iterations. Calculate ESALs, structural number (SN), and layer thickness in minutes. Introduction Designing a flexible pavement that balances cost, durability, and safety is challenging. The AASHTO 1993 method requires iterative calculations, reliability factors, drainage coefficients, and layer coefficient adjustments—all prone to human error when done manually or with a basic calculator.
That’s why I developed a that automates the entire process. flexible pavement design excel spreadsheet
Simplify Your Road Designs: Flexible Pavement Design Excel Spreadsheet (AASHTO 1993) Stop manual iterations
If you find this useful, please share it with your engineering network. Feedback and feature requests are welcome. A spreadsheet won’t replace a full pavement design package, but for 80% of routine projects—parking lots, low-volume roads, site access, and preliminary studies—it’s more than enough. It saves time, reduces errors, and gives you a documented calculation trail. Feedback and feature requests are welcome
