Asphalt pavements on bridge decks

2021-6-23  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.

Fatigue Life of Asphalt Pavements on Bridge Decks

2017-1-24  In Europe bridge asphalt pavements are paved on the insulations (waterproofing). Asphalt pavement on the bridges consists of a protective layer and wearing course. These layers are usually made of mastic asphalt MA, asphalt concrete AC and stone mastic asphalt SMA. Due to the specific conditions of the load on a bridge decks, asphalt mixes with a high content of mastic and closed structure are preferred. There are a mixture of mastic asphalt MA and SMA for the protective layer and asphalt concrete, SMA for wearing course [4,7]. Figure 1 shows the typical layouts pavement layers on the bridge decks.
