This paper reports on the development of a laboratory test method to assess the deterioration of concrete cracks and joints under low intensity, high cycle loading, typical of that found in industrial flooring, external hardstandings and rigid pavements. The half-scale prism specimen enables the impact of crack geometry, reinforcement and load magnitude to be assessed in relation to load transfer deterioration, without the need for full scale testing. Each element of the testing procedure has been developed to represent site conditions in respect to crack development, loading and support. A selection of the test results are presented which indicate that joint/crack deterioration consists of four distinct phases, each controlled by a different mechanism of material degradation. This information can be used to enhance understanding of joint/crack behaviour and their failure mechanisms, hence improving design and maintenance procedures.
