“…Indeed, the structural role of the surfacing is an essential parameter in the global behavior of orthotropic bridge (Hameau, 1981;Héritier et al, 2005aHéritier et al, & 2005bHuurman et al, 2003;Liu et al, 2006;Medani, 2006;Méhue, 1981;Nishizawa et al, 2004;Pouget et al, 2008Pouget et al, & 2009Saubot and Loup, 2004).…”

A new approach is proposed to determine the global response of an orthotropic bridge structure from the behavior of the constituent materials that are binders, aggregates and steel. Experimental results and modeling using constitutive models (2S2P1D and DBN) developed by ENTPE team are presented for the bituminous materials in the linear domain. From these results, a transformation that is independent of the introduced models allows the bituminous mix complex modulus to be predicted from the bitumen complex modulus. Then, the response of a 3D orthotropic steel deck bridge subjected to moving wheel loads is presented using numerical Finite Element Method (FEM). The influence of temperature and viscous behavior of surfacing layers on the structure response such as deflection and longitudinal stress are emphasized.

“…Slide pusher is due to the project itself, so the gap between electromagnet and permanent magnets can be small. Moreover, pushing the deck may produce longitudinal displacement between magnet and magnetic block can change spacing through hydraulic device, producing controllable magnetic force, decreasing the corresponding method to stress, and reducing the damage to the Teflon coating [9][10][11][12].…”

Millau Viaduct crosses the Tarn Gorge and is one of the highest bridges in the world. More than 20 years after its completion, it still holds the record for the highest pier in the world. It is a shining pearl in the history of human architecture. In this study, the construction processes and strategies of Millau Viaduct are introduced in detail. Results show that after the concrete pier was poured, the bridge deck was pushed forward by applying the jacking from the tail then completed the construction of the long-span bridge. In order to reduce the impact of wind during construction, the construction team improved the construction accuracy by optimizing the bridge model and using satellite positioning. Combined with understanding and perception of the high span and high-risk construction projects such as Millau Viaduct, some methods are put forward to improve the construction technology. These construction methods could be adopted in the future to reduce the risks associated with the project.

“…Two surfacing techniques were investigated. The first is a bituminous membrane surfacing (BMS), which involves the application of a modified elastomeric and plastomeric bitumen sheet reinforced with nonwoven polyester (9)(10)(11). The membrane is unrolled on the orthotropic deck after the cold application of an elastomeric bitumen primer, containing xylene solvent, and it is afterwards overlaid with a 70-mm-thick hot-mix asphalt (HMA).…”

Although steel orthotropic deck is currently the most widely adopted solution for long-span bridges, the poor adhesion to the upper asphalt layers still represents a serious problem without a clear solution. In recent decades many techniques that involve the use of special bituminous bonding coats, reinforced asphalt membranes, net-reinforced steel deck surfaces, or epoxy asphalt binders have been applied, with varying results, to improve the level of adhesion of the asphalt pavement to the steel surface. In this experimental study, two such techniques were adopted to investigate the shear resistance of steel–asphalt pavement systems. The first technique used epoxy asphalt both as a bonding coat and as a binder of the upper asphalt layer, while the second technique involved the use of a reinforced asphalt membrane that was applied on the steel deck before overlaying with conventional hot-mix asphalt (HMA). The Ancona Shear Testing Research and Analysis shear test device was used to evaluate the shear resistance of different types of HMA–steel interfaces and to investigate the effects of temperature and normal stress. The results have been compared with the shear properties of bitumen-coated interfaces, studied in previous research. The results showed that epoxy asphalt guaranteed high performance regardless of the test temperature. However, the shear resistance of the system with the asphalt membrane was lower than with the epoxy asphalt, although it was higher than the resistance of bitumen-coated interfaces at high temperatures.
