Concrete barriers prevent vehicles from entering the opposite lane and going off the road.
An important factor in the design of concrete barriers is impact load, which a vehicle exerts …

A new concrete barrier (NCB) design that separates the opposing lanes in roads was
presented and tested experimentally. The proposed design comprises three parts. The …

The traditional, triangular yield-line method used by most departments of transportation for
analyzing concrete traffic barriers and bridge rails has been largely unchanged since 1978 …

The numerical simulation for a new type of precast concrete barrier for viaducts is carried out
systematically. To obtain an accurate representation of the damage state of the concrete …

Reinforced concrete bridge parapets have important safety roles in the highway system.
Currently AASHTO and FHWA require all new permanent installation of bridge rails on the …

Test levels are defined for different types of bridge barriers utilized for different cases of
traffic conditions. The specifications for crash test levels including impact speed, impact …

For the past decade, Glass Fibre Reinforced Polymer (GFRP) has been significantly utilized
as an alternative to steel reinforcement, as the corrosion of black steel reinforcement …

This paper summarizes the research work done in Canada on steel-and GFRP-reinforced
concrete barriers. AASHTO LRFD Bridge Design Specifications specify a triangular yield line …

The main objective of this research is to design a concrete barrier that is reinforced with
glass fiber reinforced polymer (GFRP) materials. The design is based on the MoDOT Type D …

US roads carry a mix of motor-vehicle traffic, including motorcycles, passenger vehicles,
buses, trucks, recreational vehicles, and other specialized vehicles. Occasionally, tractor …
