During 1998/99, WERD asked for topics of interest affecting the European road network, with the aim of identifying any knowledge gap and to initiate future research. Long-Life Pavements (LLPs) was one of the topics suggested by the UK Highways Agency and was later endorsed by WERD as appropriate for a co-operative approach.

The European Long-Life PAvement Group (ELLPAG) was subsequently established as a FEHRL Working Group to act as the focal point for determining the way forward. Members of the Group comprise representatives of research institutes who are FEHRL members, and a member of the UK Highways Agency.

Two levels of membership of the Group have been created. Firstly, a core membership who are directly involved in the work of the Group and where representatives attend regular meetings as required. (All these members are from either the FEHRL or WERD organisations.) Secondly, there are associate or affiliate members who are kept informed of the work of the Group and contribute through supplying information as requested and commenting on draft outputs. (These members do not need to be part of FEHRL or WERD.) The current core membership is listed in Annex A.

As a result of a number of meetings of the core Group, Terms of Reference have been established for the Group and these are stated in Annexe E. In creating Terms of Reference for the Group we have had to consider the scope of the meaning of long life pavements. It has been suggested that this should not be ‘life’ related but based on the concept that a long life pavement is one that is heavily trafficked, and is designed and maintained such that no structural deterioration occurs in the main supporting layers of the pavement, whatever the traffic loading conditions. The only deterioration that occurs should be in the upper or surface layers of the pavement.

The original objectives of ELLPAG can be stated chronologically as short-term, medium term and long-term objectives:

• The short-term objective of the Group is to produce within 12 months of starting the formal project a State-of-the-art Review of current European knowledge on the design and maintenance of long-life fully flexible pavements.

• The medium-term objectives are to produce similar State-of-the-art Reviews for the other common pavement types.

• The long-term objective is to produce a user-friendly comprehensive Best Practice Guidance note on long-life pavement design and maintenance for all the common types of pavement construction used in Europe.
