Orthotropic Steel Plates for Bridge Deck Replacement
1990A large number of our nation's bridges have reached the age where serious deterioration requires replacement of the roadway deck. Where first cost is the determining factor, replacement in kind—usually reinforced concrete—is the normally accepted method.

New Composite Pavement System for Orthotropic Steel Bridge Decks
New Technologies in Construction and Rehabilitation of Portland Cement Concrete Pavement and Bridge Deck Pavement, 2009Orthotropic steel bridge decks are widely used for large and medium span bridges, however early failure in traditional asphalt concrete surfaces has proved to be a problem on high traffic routes. Consequently, a demand exists to find a durable overlay for such bridges. In this paper, four kinds of design indices are explored, based on the primary types

A new concept of orthotropic steel bridge deck
Structure and Infrastructure Engineering, 2008A new concept of orthotropic steel bridge deck is proposed to improve its durability and economy. It is suggested to hot-roll the longitudinal ribs. Thus, the ribs can be made larger and with a more effective cross section that is not possible for cold bent ribs.

Cement-Based Transition Layer for Orthotropic Steel Bridge Decks
Pavements and Materials, 2011The mechanical behavior of wearing surface on orthotropic steel bridge deck with rib stiffener, longitudinal clapboard and diaphragm was analyzed by Finite Element Method (FEM), it shows that the higher elastic modulus of the intermediate layer, the less stress in the critical fatigue parts of the surfacing and the more favorable to the whole wearing ...

Refurbishment of orthotropic steel bridge decks by bolted solutions
IABSE Reports, 2019<p>An increasing number of steel road bridges in Germany, but also in Europe and North America, show severe fatigue damages induced by the increase in heavy traffic loads. In addition, these road bridges from the 1960s to the 1980s were executed with fatigue-critical details, which are no longer state of the art today.

Construction of Asphalt Pavement for Orthotropic Steel Deck Bridge
2021The article describes the methodology of calculating and designing of the pavement on the hoist superstructure with orthotropic steel deck of the roadway. This work is a part of the planned overhaul of unique road bridge across the Severnaya Dvina River in Arkhangelsk. In accordance with current standards, the thickness of the new asphalt pavement must

A study of open rib orthotropic steel bridge decks
2022Steel orthotropic bridge decks (SOBD) have been widely used for long span bridges, but have not been heavily employed for short and medium span bridges that encompass the majority of highway bridges in the United States. The lack of robust standards and high initial cost of fabrication have deterred the widespread utilization of these bridge decks ...

Sandwich system for renovation of orthotropic steel bridge decks
Journal of Sandwich Structures & Materials, 2010A sandwich system of two steel faces and a polyurethane core is studied as a renovation system for orthotropic steel bridge decks. An experimental program has been carried out aiming to better understand the sandwich beam flexural behavior. The temperature significantly affects the sandwich flexural behavior.

Fatigue Properties Estimates of Orthotropic Deck on Steel Bridges
Applied Mechanics and Materials, 2011For estimating the fatigue properties of orthotropic deck bridges, a finite element analysis method was provided. In the method, the models of orthotropic decks steel bridge were established by using Midas and Ansys finite element software respectively, the Midas software has tracked two kinds of live load positions that corresponding to maximum and ...
