Civil
Pavement Thickness Design Calculator
Estimate the required pavement thickness for roads or parking lots based on traffic volume, subgrade strength, and design life. Essential during roadway design to prevent premature structural failure.

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.
