Abstract:

The Low-Profile barrier and its sloped end treatment were crash tested in the 1990s and found to comply with Test Level 2 (TL-2) criteria for terminals and redirective crash cushions as recommended in National Cooperative Highway Research Program (NCHRP) Report 350. The 20-inch tall Low-Profile barrier system offers advantages over traditional 32-inch tall portable concrete barriers. The reduced height provides enhanced driver visibility in highway work zones and other appropriate locations. The Low-Profile end treatment was originally designed and tested under the assumption that it would be attached to the pavement or subgrade using vertical steel pins spaced at equal intervals along the centerline of the end treatment. The purpose of these steel pins was to control the lateral deflection of the end treatment during impact. While these steel pins do an excellent job of controlling the lateral deflection, the introduction of holes into the pavement or subgrade is not desired in many applications. The purpose of the research presented herein was to determine if a non-pinned Low-Profile end treatment can comply with applicable crash test standards. The non-pinned Low-Profile end treatment performed acceptably for Tests 2-34 and 2-35 according to the criteria set forth in the "Manual for Assessing Safety Hardware" (MASH).
