Experimental Evaluation of Aluminum Bridge Deck System
TLDR
In this article, an alternative lightweight extruded aluminum deck system that has a solid surface and meets the loading requirements as well as weight and thickness limits for movable bridge decks is evaluated.Abstract:
Most of the movable bridges in the United States have open grid steel decks, primarily because they are factory assembled, lightweight, and easy to install. Open grid steel decks, however, are not as skid resistant as solid decks. Costly maintenance, high noise levels, poor riding comfort, and susceptibility to vibrations are among the other disadvantages of these decks. The objective of the research presented in this paper is to evaluate an alternative lightweight extruded aluminum deck system that has a solid surface and meets the loading requirements as well as weight and thickness limits for movable bridge decks. These aluminum deck panels with their tongue and groove connections have previously been used in Europe, mainly in Sweden. A detailed experimental evaluation of the aluminum deck system has been carried out, including static and fatigue load testing on the deck panels, as well as ancillary tests on the connections with the girders. On the basis of the in-depth experimental evaluation and the ...read more

Performance Prediction Relationships for AM2 Airfield Matting Developed from Full-Scale Accelerated Testing and Laboratory Experimentation
TL;DR: In this paper, the authors present results from nine full-scale experiments conducted on sections of AM2 matting installed on unstabilized soil and gravel subgrades with CBRs of 6, 10, 15, 25, and 100 percent, and provide improved relationships for predicting subgrade deformation underneath an AM2 installation and the associated fatigue damage when subjected to F-15E and C-17 traffic.

Structural behaviour of aluminium bridge deck panels
TL;DR: In this paper, a research program has been undertaken to develop and implement an innovative aluminium bridge deck system, which would be applicable and realizable in domestic conditions, and several service load and ultimate load tests have been carried out on the prefabricated 2.10×3.20m deck panels, in order to examine and evaluate the panel behaviour under standard truck load, and when loaded to failure.
