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.
