Powerful Features for Flexible Pavement Design
Powerful Features for Flexible Pavement Design Compliant with IRC 37 .
Guided Pavement Design
Ensure every design meets the mark through automated adequacy validation.
- Verifies fatigue and rutting criteria
- Easy Detection of under- or over-designed layers
- Convenient optimisation of material combinations and thicknesses
- Integrated cost analysis and comparison of alternative design options
Critical and Permissible Stress–Strain Computation
Simplify complex calculations with Roadax's interactive design interface.
- Instantly evaluates critical tensile and compressive strains
- Checks against permissible limits for a given design inputs
- Offers clear visual outputs and safety margins for confident decision-making
Multi-Layer Elastic Analysis
Conventional multi-layer elastic theory, the gold standard in pavement engineering.
- Computes stresses and strains across pavement layers
- Accounts for standard wheel loads, subgrade strength, and material properties
