Layer Coefficients for New and Reprocessed Asphaltic Mixes

laboratory and field measurements are consistent with the materials tested. The resilient modulus values measured show that different layer coefficients should be given to the recycled and reprocessed materials depending on the nature of the components. A list of layer coefficients is proposed for pavement design.

Pavement Structure Pavement Interactive

A flexible pavement structure is typically composed of several layers of material each of which receives the loads from the above layer, spreads them out, then passes them on to the layer below. Thus, the further down in the pavement structure a particular layer is, the less load (in terms of force per area) it must carry (see Figure 1). Figure 1.

" Causes Of Pavement Bending Damage " — Steemit

This damage has the characteristics: the width of the gap of the pavement damage is smaller or equal to 3 mm, the cause of the damage of the flexible pavement is the material for the poor pavement, the ground less stable. So that this fine crack can absorb or pass water into the surface layer (seep).
