Test and evaluation of a tire-sand inertia barrier. Paper presented at the 54th Annual Meeting of the Transportation Research Board (TRB), Washington, January 1975.

Four tests with tyre-sand inertia barriers are reported. Such barriers are intended for sites where debris scatter from sand tyres is not likely to fall on the paved roadway. The inertia barrier uses a base that is crushable, plywood disks, scrap tyres, sand and a waterproof covering. The principle of the conservation of momentum is used in the design.
