The report contains a state of the art review on strain alleviating (or stress absorbing) membranes or membrane interlayers, commonly referred to as SAMS and SAMIS respectively. These are laid over cracked pavements in order to reduce the incidence or severity of reflection cracking and consist essentially of a film of rubber or polymer modified binder covered with a layer of aggregate. Information is given on the early use of rubbers and polymers in bituminous binders and on the development of current materials. Details of the polymers and rubbers available in Australia are provided, together with an indication of their usage in each state. Australian sealing practice with rubberised binders is discussed in the text and more detailed information is provided in the appendix. Information on laboratory research and on the results of field trials is given and the advantages and limitations of both SAMS andd SAMIS are covered. The report recommends areas where future development and research work should be undertaken and an extensive bibliography is provided. (Author)
