Highway Crash Barrier

Since that time, no widespread use of tires in this application has occurred. State transportation departments generally prefer sand-filled crash barriers because they have excellent absorption characteristics and are easier to erect and dismantle.

Whole waste tires can be used for artificial reefs, breakwaters, erosion control, playground equipment, and highway crash barriers.

Highway abutments. An approach to solving a safety problem by utilizing whole scrap tires was possible [5] by constructing highway abutment crash barriers made of whole scrap tires. If effective, driver fatality or severity of injury could be significantly reduced. 

A different approach is used by the U.S. Insurance Institute for Highway Safety (IIHS) and tiie European New Car Assessment Program (EuroNCAP). In their simulations of frontal collision the crash barrier only extends into 40 percent of the vehicle s width from the driver side, and the impact speed is 40 mph (64.4 km/h). In partial overlap, the force is distributed over a... 

Civil engineering uses include large diameter pipe for culverts and air ducts and energy-absorbing highway safety devices such as crash barriers filled with polyurethane foam and barrels filled with sand installed around bridge abutments. On a more down-to-earth level, the components of portable privies are frequently rotationally molded. 

Another example is the standard on classification of motor vehicle traffic accidents published by NSC. It provides a uniform method for compiling data on highway accidents. The Federal Highway Administration (FHWA) provides formulas for calculating roadway departure crashes from crash rate data. The method helps highway planners select the types and locations for barriers and guardrails and implement other safety improvements.
