Both calculators run independently — change the inputs on either side to compare results.
Civil
Flexible Pavement Design Calculator
Calculate the required asphalt pavement layer thickness based on traffic loading (ESALs), subgrade strength (CBR), design reliability, and climate zone using the AASHTO flexible pavement method. Used by highway and airport pavement engineers.

Civil
Retaining Wall Design Calculator
Calculate active, passive, or at-rest lateral earth pressure on a retaining wall given soil properties, wall height, and surcharge loading. Use it when designing gravity walls, cantilever walls, or checking overturning stability.
