The paper presents the feedback of a series of technical seminars on bituminous binder testing and specifications, the BiTSpec seminars, held in Europe to support the present work programme for developing performance related standards for the binders used in road construction and maintenance, under the responsibility of the CEN Technical Committee TC 336. The purpose of these events was to facilitate communication at European and national levels between all the stakeholders involved in the definition and the preparation of a suitable performance-related specification system for binders. The BiTSpec project started in 2002 with regional seminars held in ten different countries and ended with a European seminar held in June 2003 in Brussels. The paper also presents the synthesis of the collective viewpoints of the European organisations EAPA (European Asphalt Pavement Association), EUROBITUME (European Bitumen Association), FEHRL (Forum of European National Highway Research Laboratories), IISRP (International Institute of Synthetic Rubber Producers) and WERD (Western European Road Directors), which express their needs and requirements related to the specification system for binders.
