First a sand asphalt SAMI 2, 5 cm, then a leveling layer CAD-12 4 cm type, and finally the surface layer with an open mixture F-10 3cm. modified asphalt was used in all these layers BITAFLEX AM3. We thank the company provided confidence in providing it.

As for the retreading, to improve the IRI on the stretch of Route intervened and asphalt layer to achieve high durability, safety and user comfort slab repair work and potholes then apply three asphalt layers were made:

1) A layer of sand asphalt as stress relieving membrane (SAMI) modified asphalt made with BITAFLEX AM3.

2) A regularization layer on the gauge with a CAD-12 type modified asphalt mixture made with BITAFLEX AM3.

3) A surface layer with an open mixture F-10.
