This paper presents the development and testing of single slope barriers with independent foundations that can be installed at a wide range of site conditions. The researchers developed designs of barriers with foundation systems by conducting a seri

In work zones in which space to place a temporary concrete barrier (TCB) is limited (e.g., zones to expand or repair a bridge), the barrier must be restrained to prevent large, lateral deflection from vehicular impact. This paper presents the develop

In 2009, the Manual for Assessing Safety Hardware (MASH) was adopted as an updated replacement of NCHRP Report 350. Under MASH, the impact severity of Test Level 4 (TL-4) (Test 4–12) was increased by 56%. Test vehicle mass was increased from 17,640

Median barriers are commonly used to separate opposing lanes of traffic on divided highways and to separate managed lanes from general purpose lanes. Concrete median barriers (CMBs) are often preferred on urban freeways with narrow medians because of

Performance limits of commonly used barriers in terms of acceptable vehicle impact heights were identified using non-linear finite element methodology. Finite element models for four widely used guardrail systems were developed. The selected guardrai

When concrete barriers are installed adjacent to drop-offs or steep roadside slopes such as 1.5H:1V, a cast-in-place concrete moment slab is usually attached to the base of the barrier to resist lateral and overturning forces during vehicle impact. C

Temporary barriers are often required to provide positive protection for motorists and workers in a highway work zone. Most highway work zones are restricted in regard to available lateral space for accommodating traffic and the work activity. Conseq
