An array of inertial barriers.

摘要

An array of inertial barriers (10, 50, 30) resting freely on a support surface (55) alongside a vehicle roadway includes a number of separate frangible containers (12), each having a peripheral side wall and a bottom portion. A core or insert (20) is positioned within each container to define an annular space between the core and the respective peripheral wall. This annular space has an average inner diameter which is at least about 25% of its average outer diameter. A dispersible material such as sand (5) is disposed in the annular spaces such that no more than 10% of the mass of sand in any container (12) of the array is disposed in an uninterrupted disc extending across the respective container (12).
