Long-term Performance of ABC
Details
• There is a reason that we use ABC• High traffic volume
• Impacts to the travel time
• Safety of workers and travelers
• So why should we sacrifice durability?• We don’t want to come back in ten years to do it again
• Impacts to travelers will most likely not reduce over time
• AASHTO Technology Implementation Group (TIG)• Established in 2001
• The start of the development of ABC in the US
• Mantra: Get In, Get Out, and Stay Out
• Get in and Get Out• Accelerated Construction
• Reduce impacts
• Stay out• Use high quality prefabrication to extend service life
• Durability is the key
• Major focus on speed• Weekend construction
• Overnight construction
• What about durability?
• Yes and no
• In this workshop, we will look at the history of durability of ABC and how we move forward• Review of in-service performance
• New specifications for durability
• Recommendations to improve durability
