Regulatory requirements for vehicle maneuvers and tire traction make it desirable that manufacturers in different countries can perform the necessary tests on identical pavement surfaces of the specified frictional characteristics. The paper deals with the problems of specifying, measuring and maintaining surface friction, particularly when tests on wetted pavements are required. The various methods for measuring friction directly or in terms of texture parameters are reviewed critically. The inhomogeneity and variability of pavement surfaces is dealt with in detail and illustrated by examples. Surface course design and construction are discussed with specific reference to the requirements of test pads and proving grounds for vehicle and tire qualification tests. The author's conclusion is that at the present state of knowledge, aggregates should be obtained from common sources and simple construction methods that can be controlled within close tolerances be employed. To achieve this goal, international cooperation is a necessity. /Author/TRRL/
