Crash Test on Guardrail Systems Embedded in Asphalt Vegetation Barriers in Accordance with GDOT Design Specifications

The Georgia Department of Transportation (GDOT) authorized a series of tests to be performed on guardrails installed in accordance with GDOT Standard Detail S-4-2002, which was used in Georgia prior to 2017 and includes an asphalt mow strip with nearby curb. The University of Nebraska’s Midwest Roadside Safety Facility (MwRSF) was selected to perform the tests in accordance with AASHTO’s Manual for Assessing Safety Hardware (MASH 2016). A single crash test was performed using Test Vehicle 1100C, a small passenger car. The crash test results exceeded multiple MASH safety evaluation criteria, including occupant compartment deformation, windshield crushing, and maximum allowable Occupant Ridedown Acceleration (ORA). Thus, the Midwest Guardrail System (MGS) installed in an asphalt mow strip with a curb placed behind the barrier was deemed to be unacceptable according to the TL-3 safety performance criteria for test designation no. 3-10 provided in MASH 2016.
