Using Titanium Bars to Strengthen Bridges
A proposed ASTM standard will allow titanium alloy bars to be used as near-surface mounts in civil structures.
Posted: August 3, 2018
The ASTM International (West Conshohocken, PA) committee on reactive and refractory metals and alloys is developing a proposed standard (WK63793) that allows titanium alloy bars to be used as near-surface mounts in civil structures that are used to repair and strengthen concrete bridge girders and extend the life of older bridges. Techniques involving the use of titanium near-surface mounts offer an effective system for the repair of deficient civil structures in the United States and globally.
Jill Adkins, ASTM member and infrastructure development manager at Perryman Company (Houston, PA), noted that there are no specifications covering this use for titanium. The proposed standard will be an internationally recognized material specification that can be used as a reference document in design guides and individual state department of transportation (DOT) specifications, along with other governing bodies such as the American Association of State Highway and Transportation Officials (AASHTO). To purchase these standards, call 877-909-ASTM or contact sales@astm.org.
