Development of Installation Guidelines for Midwest Guardrail System in Combination with Roadside Curbs for MASH TL-3 Applications
While curbs are useful for many functions, highway design policies typically discourage
the use of 6-inch- to 8-inch-tall curbs on high-speed roadways due to their potential to cause drivers
to lose control in a crash.
NCHRP Research Report 1089: Development of Installation Guidelines for Midwest Guardrail System in Combination
with Roadside Curbs for MASH TL-3 Applications,
from TRB's National Cooperative Highway Research Program,
develops guidelines for the use and placement of
31-inch-tall Midwest Guardrail System adjacent to curbs under
Manual for Assessing Safety Hardware (MASH) Test Level 3 impact conditions.
