Influence of Traffic Load on the Crack Widths of Full Jointless Bridges

Abstract:

Traffic load not only increases the original crack widths of the reinforced approach pavement of full jointless bridges, but also generates the development of new small cracks. Using lab experiments, this paper mainly studies the influence of traffic load on the crack width of the approach pavement of full jointless bridges. The results show that the load of traffic not only increases the crack width, but also increases the vertical settlement. In order to control the crack width we need to consider the influence of the traffic load. And the traffic load influence factor here we choose to be equal to 1.45.
