Thin Bituminous Surface Overlay and Surface Treatments are typically protective intervention in pavement maintenance with a minimum thickness of around 12-15 mm, or about half the thickness of similar sized conventional asphalt wearing course mixes. The Ultra Thin Overlays have minimum thickness of around 3-4 mm and, as thin overlays and surface treatments, but in different way, they allow to extend the durability with limited costs, reducing the points of weakness, sealing cracks and voids, improving water removal and reducing aging and raveling. The paper describe how opportune and targeted mix design can increase the skid resistance, the optic performances, acoustics and the superficial outflow, the resistance to the abrasion, high temperatures, etc.

Abstract

Thin Bituminous Surface Overlay and Surface Treatments are typically protective intervention in pavement maintenance with a minimum thickness of around 12-15 mm, or about half the thickness of similar sized conventional asphalt wearing course mixes. The Ultra Thin Overlays have minimum thickness of around 3-4 mm and, as thin overlays and surface treatments, but in different way, they allow to extend the durability with limited costs, reducing the points of weakness, sealing cracks and voids, improving water removal and reducing aging and raveling. The paper describe how opportune and targeted mix design can increase the skid resistance, the optic performances, acoustics and the superficial outflow, the resistance to the abrasion, high temperatures, etc.
