SEGMENTAL BLOCK PAVEMENTS - OPTIMIZING JOINT WIDTH AND JOINT MATERIAL

Following a study of the mechanisms occuring within the bedding and the joints of segmental block pavements it was realized that further work was needed to study the effects of various jointing materials and the effect of varying the joint width between individual segmental blocks. A method of evaluating the interfacial strength of the joints by extracting individual blocks was developed. A range of optimum widths and materials for the joints was identified. A site survey of precise joint widths was made to relate the optimum conditions determined by the experiments with the practical conditions achieved during construction. (Author/TRRL)
