The 685 mm high version (SBC01a) is similar to the Texas T201 and California Type 26 bridge railings which have not been crash tested although their reinforcement details are similar to other 685mm high tested bridge railings. SBC01b and SBC01c have been crash tested and satisfy AASHTO Performance Level 2 and 3 respectively. The Performance Level 2 and 3 versions are listed in the 1990 FHWA memorandum on crashtested bridge rails as systems 17 and 22 respectively. This drawing and specification address only the bridge railing and not the design or detailing of the bridge deck. Only reinforcement directly related to the bridge rail is shown. Bridge decks should be designed to develop the full strength of the bridge railing.  Y "* COMPONENTS ă Concrete shall develop a minimum 28day strength of not less than 28 MPa. The concrete shall use a cement conforming to AASHTO M85 (ASTM C150) Type I or II. Reinforcing steel shall be Grade 400 MPa and shall conform to either of the following: (a)XEpoxycoated deformed bars as specified in AASHTO M284M (ASTM D3963M).(# (b)XAASHTO M31M (ASTM A615M) deformed and plain billet steel reinforcing bars for use with calcium nitrite corrosion inhibitor (30% calcium nitrite solution).
