Find basic tips on using our deck overlay systems. These deck overlay systems are designed to protect as well as beautify any concrete surface.
Ramböll A S, Skeppsgatan 5, 211 11 Malmö, Sweden martin.persson ltu.se martin.persson Concrete overlays on bridge decks are expected to be more durable as compared with the more common asphalt solution. Besides cast concrete overlay, see . Material properties were documented on reference specimens.
Overlays. An overlay panel carries messages and manufactured in any kind of stable plastic material such as polycarbonate, which is highly resistant to external influences. Equipped with back screen printing, embossing and adhesive tape. The printing is thus protected and the product gives a very professional impression.

paving materials (Hulsey et al., 1999). Asphalt mixture overlays are often used in overlay systems because they provide riding comfort and have a relatively low density, thus reducing the dead load of bridges (Huang et al., 2003). A bridge deck asphalt overlay system generally consists of asphalt surface layers and an
