Work Zone Traffic Management Synthesis: Tiedown Methods for Precast Concrete Safety Shaped Barriers

This report is a synthesis of research findings and current practices regarding the design and application of systems for anchoring (tieing down) portable concrete safety shaped barriers (CSSBs) to highway pavements. The presented information is based on a literature review, field observation and discussions with highway officials in a selection of states. The report presents design graphics on a number of methods for controlling sliding, tilting and overturning of portable CSSBs, identifies areas for research, and makes recommendation regarding practices and information that should be included in the AASHTO Roadside Design Guide.
