A PROBLEM IGNORED: HIGHWAY BRIDGES AND AUTOMATED TRUCK PLATOONS
34
With automated truck platoons - trucks controlled by automatic systems that drive very close together - expected to come to Australia, one question that industry hasn’t thought about is the impact of these platoons on Australia’s aging bridge infrastructure. Here, Colin Caprani, asks if our bridges can handle it?

CORROSION REMAINS A COMPLEX CONCERN
ACHIEVING SUSTAINABLE AND DURABLE BRIDGES
Sustainability, limited resources and environmental concerns are increasingly front of mind for bridge design and optimised maintenance of bridges. It’s important to look at whole of life costs as well as alternative materials to improve in service life and to minimise greenhouse gas emissions. We spoke to Dr Richard Yeo, Program Manager, Assets, at Austroads, to find out about some of the innovative research that Austroads has been undertaking on bridges and how the results could change the way bridges are designed and constructed.
