The calculation process is summarized in Figure 5.37:
Check Deformation
Sub-base
Check Deformation Foundation
Check
Fatigue and Breaking strain
Check Remaining Aspects
Traffic load
- Maximum wheel load - Tyre pressure
Sub-base information
- Viscosity
- Dynamic elasticity module
Establish layer thickness, in programme
Calculate stresses strains and
displacements
Check Pressure Strength Foundation
Optimize construction
Material properties
- Viscosity
-Dynamic elasticity module
Figure 5.37 Procedure for Dimensioning pavement Structure
After a initial pavement design calculation has been made it is tested against the different failure mechanisms that can occur. This next sections explain, step-by-step, what must be done.
