Interactive Guide

Choose between flexible (asphalt) or rigid (concrete) pavement based on your project requirements.

Enter expected traffic load in msa (million standard axles) or ESAL (equivalent single axle loads).

Specify material characteristics for each pavement layer including CBR, modulus values, etc.

Consider climate, rainfall, temperature, and groundwater conditions that affect pavement performance.

Analyze the recommended layer thicknesses and design parameters for your pavement.
Quick Tips
  • Higher traffic loads require thicker pavement sections
  • Poor subgrade (low CBR) needs thicker sub-base
  • Consider drainage for long pavement life
  • Rigid pavements perform better in heavy traffic
