The RER01 or RLR01 rubrail is attached using an FBB04 guardrail bolt.11 TIMBER MEDIAN BARRIER POST11 PDE1511 11 RS noted we should have a tolerance on the dimensions between bolt holes. Since the holes are 4 mm larger than the bolts, I used a tolerance of + or 4 (MHR:9/12/93) Tolerances removed as per reviews (MHR:121594). There are three holes in the post so that the same posts can be used with (1) wbeam barriers, (2) wbeam barriers with rubrails and (3) thrie beam barriers (MHR:9/12/93). Paul Huck notes that the minimum inertial properties are calculated based on minimum dimensions of a rough sawn post. Dimensions for a surfaced post would be somewhat less. I have removed the "rough sawn" phrase so the spec covers the minimum dimensions of rough sawn or surfaced timber posts (MHR:9/12/93). I changed things again and now calculate properties based on nominal dimensions as per reviewer's recommendations (MHR:121593) Dusel says that 10 mm tolerance on W is inconsistent with the grading specifications. The best I could come up with from the Wood Handbook is to show this tolerance as 12. I have gone back and changed all the wood post width tolerances to be 12 instead of 10. (MHR: 111493). The post review group recommended removing tolerances and let the grading specs take care of that (MHR:121593).)0*0*0*ԌDusel also suggested that instead of the phrase "with a stress grade of 8 MPa" I should use "having a minimum design stress value of 8.27 MPa for extreme fibers in bending." While I agree that is the stress referred to by the stress grade value I think it is best to stay with the terminology used in the timber industry so I have left it simply as a stress grade.

Floyd Bowlby thought the two lower holes are too close for proper manufacturing (there is only 10 mm of material between holes). I rechecked the dimensions and they are correct as shown. Dusel also thinks the 60mm hole should be moved up 10 mm to prevent water ponding. Since the detail shown corresponds to current BCT posts I've left the detail as is (MHR:10193). Floyd Bowlby suggested we require grade SYP No.2 or better. The Wood Handbook says that either stress grade or finish grade should be specified but not both so I have left the spec in terms of the 8 MPa stress grade (MHR: 101393). I am using the same post for both the BCT and MELT. There are three sources for this drawing. The FHWA MELT drawings, the 1979 guide (P6079, although this is not the short post) and a drawing by SYRO (SK8681). Unfortunately they are all a little different. I have relied primarily on the FHWA MELT drawing. The rail height of the FHWA version is about 10 mm higher than the SYRO version (MHR:31094). In discussions with Steve Eastman and)0*0*0* Jim Hatton I have standardized on the ET2000 post which can be used for the MELT and BCT. The breakaway hole size was changed to 64 mm which is a standard bit size and big enough to allow the pipe sleeve to fit inside. The breakaway hole has also been moved up 14 mm.
