AASHTO Flexible Pavement Design Excel Spreadsheet: Development, Validation, and Application

Let’s walk through how to construct this masterpiece.

Input design ESALs, reliability, subgrade ( M_R ), and serviceability loss. aashto flexible pavement design excel spreadsheet

Add a Solver model to minimize total pavement cost (material costs per inch) subject to:

Challenge 1: The Iterative Nature of the SN Equation Challenge 1: The Iterative Nature of the SN Equation

Challenge 2: Units Consistency

Challenge 3: Drainage Coefficients ($m_i$) Challenge 2: Units Consistency

Create a data table that varies M_R and ESALs simultaneously. Use Excel’s Data Table feature to generate a 2D matrix of required SN. Then use conditional formatting (color scales) to highlight risk zones.
