Do you have any suggestions for blockout materials on the
|Date||September 18, 2017|
For a replacement to wood blockouts in approach guardrail transitions, one could use steel sections. In the mid to late 1990s and later in mid 2000s, we used a steel tube shape (TS7x4x3/16) with sloped top for blockouts that matched up to W6x9 steel transition posts.
For W6x15 posts, one might use (1) a steel tube section of similar depth to wood section and shortened length or (2) a WF section of similar depth to wood section and shortened length with a backup plate between rail and block. The shortened blocks have been used in the stiffened thrie beam region.
Let us know what option you like best so that we can suggest a few options. Thanks!
