Many billions of EUROs are spent on road construction and maintenance each year, and road
transport is the primary method of mobility for European citizens and products. There is a
continuing requirement for more efficient methods of pavement design, aimed at producing
solutions which are less disruptive to the environment and to the road user, as well as being more
economic and of a higher quality than those in present use. This applies, not only to the design of
new infrastructures, but also to the rehabilitation of the existing ones.
Although based on the same basic principles, current European pavement design methods are
quite different from each other, and the need for industry to cross borders calls for harmonisation
of pavement design methods. In summary, there is a gap between the actual situation with
respect to pavement design, and the ideal harmonised European pavement design method, which
will take into account actual traffic loads and climatic conditions throughout Europe, as well as
new materials and new types of pavement structures.
In order to promote European co-operation in this field, the Forum of European National
Highway Research Laboratories (FEHRL) included a project on pavement design in its Strategic
European Road Research Programme (SERRP). A proposal for an Action on pavement design
was consequently submitted to COST Transport, and a Technical Sub-Committee was set up in
early 1995, in order to prepare a work plan. COST Action 333 (Development of New
Bituminous Pavement Design Method) was formally initiated in March 1996 and, during its
period of operation a number of additional countries and organisations joined the Action. At the
end of the Action, 20 countries signed the Memorandum of Understanding and were
participating in the Action.
The main objective of COST Action 333 is to contribute to the development of a coherent, cost-
effective and harmonised European pavement design method, which will take into account
vehicle loading, climatic conditions and the use of new materials. This project focuses on
bituminous pavements (flexible and composite) while concrete pavements are studied in another
SERRP project (CON-PAV).
The Technical Sub-committee defined a detailed work programme, which focused on
information gathering, identification of requirements and selection of design elements. This
having been achieved, it is now possible to begin the task of developing the design elements and
producing a coherent, cost-effective and harmonised pavement design method that can be
applied throughout Europe. Chapter 13 (Outline Harmonised Design Method) describes the way
in which this can be achieved.
The initial work programme of COST 333 was divided in two main tasks. The first task,
corresponding to information gathering, addressed the terminology associated with pavement
design, and reviewed established pavement design methods together with the requirements and
deterioration mechanisms of the main pavement components. In the second task, the
requirements for a new improved Europeant design method were established, in terms
of traffic characterisation, climatic conditions, materials and models.
The COST Action was originally scheduled to end in March 1998. However, the support for the
Action exceeded expectations, with 20 countries participating and the possibility of undertaking
a dedicated trials programme in an accelerated pavement testing facility in Switzerland. Support
from industrial representative organisations v/as also provided during the course of the Action,
via the participation of EUROBITUME and the European Asphalt Pavement Association
(EAPA). Therefore, the Technical Committee on Transport approved a one year extension to take
advantage of this extensive pool of knowledge and expertise, as well as the results from the trials
in Switzerland. In addition, the role of design models in dealing with pavement rehabilitation
was added to the initial work programme.
As an initial output from COST 333, a glossary of terms associated with pavement design in
English, French, Gemían and Spanish was prepared, which was continuously updated during the
course of the Action, as the work in other tasks progressed.
The review of the requirements and deterioration mechanisms of the main pavement components
has demonstrated that there are discrepancies between the perceived modes of pavement
deterioration and those observed in recent or on-going pavement studies, and the modes of
pavement deterioration on which current pavem
