The design principle for repair solutions
Types of road damages, causes and diagnosis

Once a summary has been drawn up for each type of cut encountered, it is important to carry out a computational analysis which will enable us to decide on :

• the structure's compliance with traffic requirements (design and permissible values);

• the thickness of a particular layer;

• the bearing capacity of the subgrade ;

• freeze-thaw compliance (IA ≥ IR).

This analysis is carried out in accordance with the calculation phase detailed in pavement design standard NF P 98-086, and generally using ALIZÉ software.

The calculation flowcharts are shown...
