A modeling to understand where a vertical crack can propagate in pavements

Résumé

To understand how a pre-existing vertical crack can propagate and damage pavements an alternative modeling is proposed to be used. For the multilayered pavement structures, the simplified modelling, named the multi-particle model of multi-layer materials (M4) with 5n equilibrium equations (n: number of pavement layers) is linked to the Boussinecq solution for the soil (Tran, 2004) (Chabot et al., 2005). This approach has the advantage of reducing the real 3D problem to the determination of regular plane fields (x,y) per layer and interface. Heavy loads, thermal loadings and thermal shrinkage phenomena have been integrated and validated with respect to finite element computations. It shows that the bond between layers near vertical cracks is damaged by normal and shear stresses. These combined effects are proposed to be medeled to understand corner crack initiation phenomenon of cemented concrete slab. Surface observations on concrete pavements with joints help the discussion.
