Abstract
The results are reported of four full-scale crash test conducted on inertia barriers using scrap tires as containers for the sand mass. The first barrier utilized additional tires with empty beverage cans in the annular space and handed together for a support base. The bases of the scrap tires collected under the front of the impacting vehicle (a 4290 pound 1967 Dodge Monaco at 64 mph) and caused it to ramp upward. The second scrap tire-sand barrier utilized a 14 gage welded wire cage to support the modules. The ramping of the vehicle was stopped smoothly.
