Asphalt pavements on bridge decks

In chapter 2 the layers used on the bridge decks are described. In general, the asphalt bridge pavement system can be split into four different layers: a sealing/bonding layer (primer), a waterproofing layer, a protecting layer and the asphalt surface layer. These four layers are described.

GPR use on asphalt bridge decks Asphalt magazine

Asphalt pavements are good for bridge decks because they prolong their life. They are not affected by deicing salts and, if properly constructed, can waterproof the bridge floor, which prevents water and salts from damaging it. Asphalt surfaces are also highly skid-resistant, providing a safe bridge deck surface.
