Abstract
An end treatment array for crash attenuation includes a transition barrier module formed of side walls, end walls, a top wall, and a bottom wall, wherein the module walls together define an enclosed interior space. The end treatment array further includes a containment impact sled having an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module.

24. A containment impact sled for use in an end treatment array for attenuating the forces generated by a vehicular impact, the containment impact sled comprising:
-
a frame extending in an axial direction and comprising; a first side frame member; a second side frame member spaced from the first side frame member; and an end frame member extending across a width of the frame and securing the first side frame member to the second side frame member, said frame members together defining an interior space; wherein the containment impact sled is adapted for attachment to an adjacent barrier module in an assembled end treatment array in such a manner as to contain a substantial portion of said adjacent barrier module within said interior space when the end treatment array is assembled. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A method of assembling an end treatment array for protecting a fixed structure from an impact by a passing vehicle, the method comprising:
-
securing a plurality of ballast-filled hollow plastic barrier modules together in an axial array; securing one end of a transition barrier module to one end of the array of ballast-filled hollow plastic barrier modules, the transition barrier module being unfilled with ballasting material; and securing a containment impact sled to the other end of the transition barrier module, wherein the containment impact sled comprises a frame defining an interior space, the securing step including disposing the frame about the transition barrier module so that a substantial portion of the transition barrier module is contained within the interior space. - View Dependent Claims (32, 33, 34)
