The layers perfectly united support traffic loads
In a preliminary operation, surface deformations are eliminated through cold milling machines equipped with fine milling drums in order to create a uniform road surface, slightly rough. The texture of the road produced by fine milling offers an ideal base assuring an excellent adherence with the fine pavement layer to be applied. A paver with an integrated spraying module is preferably used when paving the thin layer. An adhesive layer of bituminous emulsion modified with polymer for sealing the base is automatically applied. At the same time, it paves an asphalt fine surface of only 1.2 to 2.0 cm thick.
Rollers create a uniform road surface
Compaction is a great challenge when paving fine layers in hot applications since it requires that the layers homogeneously compact themselves, but without causing irregularities on the surface. Dynamic compaction with oscillation is ideal by assuring that the underlying cold layer is not damaged by compaction. It is also possible the static compaction, but with no vibration.
The economic use of the material saves costs
The thickness of small layer of the new surface course helps to keep down the costs of this rehabilitation method. The fine layers pavement in hot applications uses about 30 Kg to 50 Kg of asphalt mixture per m2 of the new surface course which is up to 50% less in comparison with the conventional measures of grinding and filling. Because it is useful for saving natural resources, paving fine layers in hot applications is also beneficial for the environment.
