Book Description
A composite structural system consisting of an orthotropic steel bridge deck, waterproof prime, binding course, and wearing surface is complicated. To simplify the analysis of such systems, general elastic and continuous structure theory is applied to the asphalt pavement on steel bridge decks to determine the magnitude of the strain. Large differences in mechanical results have been previously obtained in assessments of steel bridge deck pavements. Few studies have focused on the mechanical state and time-dependent response of a realistic steel bridge deck wearing surface because of the difficulty of measuring the strain of the pavement on a steel deck of a long-span bridge that is in service. This study performed static and dynamic loading tests on an actual long-span steel bridge and analyzed the characteristics of the time-dependent strain response of the bridge deck wearing surface. The results demonstrate that the asphalt wearing surface exhibited significant loading time and rate-dependent characteristics under both static and dynamic loading conditions. The test analysis results also revealed that the axle load, vehicle speed, and longitudinal slope of the bridge had significant effects on the mechanical responses of the bridge deck wearing surface. Based on a comparison between the finite element numerical simulation results and the measurements obtained from testing the actual bridge, the magnitudes of the mechanical strain responses of the wearing surface on a steel bridge deck under the dynamic wheel load of a vehicle were analyzed assuming that the wearing surface is elastic and that the elastic modulus can be determined from a four-point bending test. However, the cumulative effect of plastic deformation must be considered when analyzing the fatigue damage of a permanent wearing surface.

Book Description
Many inspections of the pavements of orthotropic steel bridge decks show longitudinal cracks above the connections of the deck plate to the main girders and ribs. by using a simplified model for analysing the behaviour of the pavement and comparing the theoretical results with damage records, the ultimate resistance of the pavement is defined, and minimum stiffness requirements for orthotropic decks are derived. these serviceability limit states have been included in a recent draft of the german steel road-bridge code din 18809. theoretical studies of the material behaviour lead to proposals for the minimum strength requirements for bituminous pavements, which may be used in conjunction with the results of material tests. this procedure will improve the strength design of bituminous bridge pavements.

Book Description
This book presents new studies dealing with the attempts made by the scientists and practitioners to address contemporary issues in pavement engineering such as aging and modification of asphalt binders, performance evaluation of warm mix asphalt, and mechanical-based pavement structure analysis, etc.. Asphalt binder and mixture have been widely used to construct flexible pavements. Mechanical and Chemical characterizations of asphalt materials and integration of these properties into pavement structures and distresses analysis are of great importance to design a sustainable flexible pavement. This book includes discusses and new results dealing with these issues. Papers were selected from the 5th GeoChina International Conference 2018 – Civil Infrastructures Confronting Severe Weathers and Climate Changes: From Failure to Sustainability, held on July 23 to 25, 2018 in HangZhou, China.
