Fatigue Life of Asphalt Pavements on Bridge Decks

Influence of temperature action on the fatigue effect of

With regard to the steel deck of Runyang Suspension Bridge, the influences of temperature changes of pavement on the fatigue effects of two types of welded details are investigated based on monitoring data. Because of large amount of elements in the global finite element model of Runyang Suspension Bridge, the sensitive parameters of a simplified finite element model for the fatigue analysis

Fatigue behaviour of asphalt concrete beams reinforced by

The test results showed that the mean fatigue life of hot mixture asphalt (HMA) beams had been extended to more than 8.81 times with 3-mm thick GFRP sheets pasted on the top. Second, the stress and strian behaviour of the four-point bending fatigue test specimen was simulated by the finite element method.

This system is primarily composed of an asphalt pavement, but it can include primers and paving membranes, bond coats and paving fabrics. 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 surface layer (asphalt).

Application of Epoxy-Asphalt Composite in Asphalt Paving

One of the failure mechanisms associated with asphalt paving layers, especially on steel deck bridges, is large permanent deformation, which adversely affects its long-term performance in service. Thus, epoxy resin was introduced in asphalt paving industry to tackle permanent deformation of asphalt mixtures due to its thermosetting nature. In this review, epoxy resin as a dominant component of

Structural Optimization of Steel—Epoxy Asphalt Pavement

Fatigue cracks often occur in the deck asphalt pavement of steel bridges at the top of the longitudinal stiffening rib. To prevent this issue, the traditional design strategy of the steel bridge deck asphalt pavement structure was optimized, and a new approach is presented. This optimization technique exploits the strength simulation of the steel—epoxy asphalt pavement structure, and the

Compacting Hot Mix Asphalt Pavements: Part I | Roads & Bridges

Tests have shown that reducing the air-void content of a given asphalt-concrete mix from 8% to 5% can double the fatigue life of the pavement. Thus, for a given thickness of HMA as part of the pavement structure, the ability of the mix to carry load can be increased significantly when the mix is compacted to a lower air-void content.
