Webdefects [3]. Therefore, it is necessary to develop the stress-strain models of SFP. As a first study on the stress–strain relationship of SFP containing waste tire rubber (WTR) and natural zeolite as cement replacement on filling mortar, in this study, a stress-strain model under uniaxial compressive load is developed [4]. WebCrumb rubber mortar (CRM) made from scrap tires can be used in highway, high-speed railways, and airport pavements as a structural material, which may help to solve the problems of raw material shortage and waste tire pollution at the same time. To develop it, a systematic study of the stress-strain behavior of CRM under static and dynamic … WebStress-Strain Curve of Rubber.
