| Abstract: | the use of Breakaway hardware has become a cornerstone of the forgiving roadside concept since its inception in the mid-1960s.NCHRP Report 350 is the main criteria to determine if a support is considered breakaway.The release mechanism maybe a slip plane, plastic hinge,fracture element,or a combination of these. The installation of Breakaway hardware should consider several factors.Otherwise,Breakaway hardware also in- creases the risk of occupants. |
