TRB Webinar: Design of Interchange Loop Ramps and Pavement/ Shoulder Cross-Slope Breaks
TRB conducted a webinar on Monday, November 13, 2017 from 2:00 PM to 3:30 PM ET that featured research from the
National Cooperative Highway Research Program (NCHRP)’s
Web-Only Document 227: Design Guidance for Interchange Loop Ramps and Pavements/Shoulder Cross-Slope Breaks.
This webinar presented information about how to develop improved design guidance for interchange loop ramps. Presenters described the new design guidelines based on observational field studies and safety analyses. They also reviewed AASHTO’s current design policy for cross-slope breaks on superelevated horizontal curves, based on vehicle dynamics simulation modeling and a crash analysis.
The slides are available. Contact Reggie Gillum at RGillum@nas.edu for a copy of the recorded webinar.
