Aashto Flexible Pavement Design Excel Spreadsheet !!exclusive!!

A AASHTO flexible pavement spreadsheet includes:

The required Structural Number is compared against the sum of contributions from individual layers—surface course (asphalt), binder course, base course, and subbase course—to ensure the total exceeds the required value. aashto flexible pavement design excel spreadsheet

The structural number ($SN$) is solved iteratively using: $$\log_10(W_18) = Z_R \cdot S_o + 9.36 \cdot \log_10(SN + 1) - 0.20 + \frac\log_10[\frac\Delta PSI4.2 - 1.5]0.40 + \frac1094(SN + 1)^5.19 + 2.32 \cdot \log_10(M_R) - 8.07$$ iterative process that balances traffic loads

Designing flexible pavements using the is a complex, iterative process that balances traffic loads, soil strength, and material properties. Using an Excel spreadsheet transforms this tedious manual calculation into a rapid, accurate engineering tool. 1. The AASHTO 1993 Design Equation aashto flexible pavement design excel spreadsheet
