Printed in Belgium In Memoriam: RAY GODDARD
Ray Goddard served as the European Commission (COST Transport) representative and Scientific
Secretary on COST Action 325 (New Pavement Monitoring Equipment and Methods) Technical Sub-
Committee throughout the preparatory period during 1993 and early 1994. Following the signature of
the Memorandum of Understanding in 1994 by the founder nations, he then carried out the same duties
for the Management Committee until his untimely death in August 1994.
Ray made a huge contribution to the development of the Action as the principal link with the European
Commission, and was well known as a very efficient and hard-working individual who was also a
friend to all the Committee members. He had time for each individual, and used his linguistic abilities
very effectively to make each member feel at home and to encourage communication within the group.
We all miss him both as a friend and as a colleague.
This publication is dedicated to him in memory of his work and to express our gratitude for all his
effort. CONTENTS
