Abstract

This paper presents findings of an investigation of the safety performance of culvert safety grates when installed on slopes as steep as 3:1, as recommended by the AASHTO Roadside Design Guide (RDG). LS-DYNA modeling was used to identify critical impact conditions for roadside culvert grates installed on 3:1 slopes. Two full-scale vehicle crash tests were conducted under the guidelines of NCHRP Report 350 on a 6.4- × 6.4-m (21-×21-ft) culvert safety grate installed on a 3:1 slope. The full-scale crash tests demonstrated that the AASHTO RDG recommended safety grates provide acceptable safety performance when installed on 3:1 slopes.
