Book Description
Two vehicle crash tests were performed on a retrofit concrete glare screen slipformed on top of an existing 32-in. high concrete safety shape barrier. The concrete glare screen is intended as a replacement for the current standard expanded metal mesh glare screen. This concrete glare screen is 20 in. high, 6 in. thick at the base and tapers slightly to 5 in. thick at the top. Reinforcing consists of two longitudinal #4 bars tied to vertical #5 hoops (inverted U-shaped stirrups). At the base of the glare screen is a 3/4-in. chamfer to match that at the top of the concrete barrier. The two test vehicles included a pickup truck ballasted to 5390 lbs. travelling 55.3 mph and impacting at 20 deg; and a large car ballasted to 4360 lbs, travelling 56.2 mph and impacting at 25 deg.

Book Description
A comprehensive research program was conducted to appraise performance of concrete median barriers. Investigations included twenty-four crash tests which evaluated performance of barrier profiles, precast designs, and end treatments. Theoretical investigations using a mathematical crash simulation program identified a new barrier shape which was crash tested to compare performance with currently used profiles. Load and stability criteria were determined from experiments and used to analyze barrier alternatives.
