Highways Agency Manual of Contract Documents for Highway Works

Prior to the 2002 TSRGD, roadstuds were required to be type approved by the Secretary of State of the Department for Transport. The approved products were formally listed in the HA's Standard Advice Note, SA1/2001 which formed a part of the Manual of Contract Documents for Highway Works (MCHW).

SA/2001 listed various products and but some of those are no longer available on the market. However, currently available products which meet the performance requirements of the 2002 TSRGD are now listed in the REMA web site, www.rema.org.uk, but representing members certification only. The Highways Agency has a revised document reference SA1/05 being published in August 2005 at present only available from the stationary office.

Active studs fall outside the scope of the European standard requiring type approval under directions 57 and 58 of the TSRGD. This is clarified in a recent REMA bulletin 'Retoreflecting road studs and the law'.
