Calculation:

Designer/Checker:

Input:

Metric Units

Required Equivalent (18 kip or 80.07 kN) Single Axle Loads (ESALr)

Standard normal deviate (ZR)

Std. error of traffic pred/perf. prediction (So)

Terminal serviceability index (pt)

Diff. between des. and term. service indexes (dPSI)

Concrete modulus of rupture (flexural strength) (Sc - psi or kPa)

Drainage coefficient (Cd)

Load transfer coefficient (J)

Elastic modulus of concrete (Ec - psi or kPa)

Modulus of subgrade reaction (k - pci or MPa/m)

Proposed slab depth/thickness (D - in or mm)

Output:

ESAL =
