eng.pavement-design-AASHTO Calculator
Calculates flexible pavement design thickness using the AASHTO 1993 method from traffic loading, subgrade modulus, and reliability. The AASHTO pavement design equation balances traffic loading (ESALs) against pavement structural capacity (SN) and subgrade strength (Mr).
Inputs
W18 Esals
Reference formula or conversion factor shown for context.
Cbr Subgrade
Reference formula or conversion factor shown for context.
Reliability Pct
Reference formula or conversion factor shown for context.
Results
resilient modulus MR (psi)
Sample size or count used in the calculation.
estimated SN (AASHTO iterative)
The value at the specified point or condition.
ZR for 95% reliability
Reference formula or conversion factor shown for context.
