In a recent post I expressed some doubt about the usefulness of the UK’s TD 9/93 (part of the “Design Manual for Roads and Bridges” (DMRB)). If any users of TD 9/93 also have some doubts, help may be available – it looks as if the UK government approves the use of alternative standards such as those produced by Turkey.
This seems to be the implication of some text in another volume in the DMRB : “Part 2 – GD 01/15 – Introduction to the design manual for roads and bridges (DMRB)”. This volume has a section on “mutual recognition”, which in paragraph 1.7 says:
1.7 Where there is a requirement in the DMRB for compliance with any part of a “British Standard” or other technical specification, that requirement may be met by compliance with:
a standard or code of practice of a national standards body or equivalent body of any EEA state or Turkey;
any international standard recognised for use as a standard or code of practice by any EEA state or Turkey;
a technical specifcation recognised for use as a standard by a public authority of any EEA state or Turkey; or
a European Technical Assessment issued in accordance with the procedure set out in regulation (EU) No. 305/2011;
Since arguably the DMRB is itself a “technical specification”, it looks as if, rather than use the DMRB, UK road designers can go to design standards from other countries such as Turkey and Iceland (Iceland is part of the EEA).
