Title: Minimum Thickness of Asphalt Concrete Pavement for Small and Medium-Span Beam Bridge
Abstract: A suitable temperature field to import solid model is established according to the climatic characteristics of the Inner Mongolia Autonomous Region and it makes an analysis on the effect of changes of pavement modulus and thickness on pavement force. The result shows that various control indexes of the pavement can have smaller values on condition that the modulus ratio of the upper and lower layer of the pavement is respectively1400/1800, 1600/1800, and 1600/1600. And the proper smallest thickness of the asphalt concrete pavement is9cm. Through analyzing the working condition of asphalt concrete bridge deck pavement under the different waterproof bonding layer thickness and different waterproof bonding layer modulus, it can be sure that the thickness of waterproof and cohesive layer can be taken at 5mm and the modulus can be taken at 100~200MPa.
