This paper describes the construction and testing of a concrete block pavement. The test pavement, 6 M x 3 M, was constructed on a heavy clay subgrade; it had a tapered sub-base varying from grossly inadequate to reasonably strong. The effect of sub-base thickness on surface deformation and the development of interlock between the individual blocks are examined and various types of failure described. The overall behaviour of a block pavement is compared to that of traditional asphaltic materials and conclusions are drawn regarding the depth of sub-base required for UK roads. Before describing the experiment the paper gives a brief history of the use of concrete blocks both in the UK and abroad. /Author/TRRL/
