Abstract: A new type of composite structure of tire and soil was proposed. In order to study the mechanical properties and working mechanism of it, the mechanical properties of tire materials were verified by the experiment of the tire strip firstly. Then the vertical and radial stress-strain curve of the composite can be obtained from the unconfined compression test of the tire-soil composite, values of compressive strength and elastic modulus of the respective composite were obtained in a certain compression deformation. The analysis of the relationship between the load and the deformation of the test provides reasonable mechanical parameters and reference for the application of waste tires in the practical engineering.

Keywords: tire; soil; composite structure; compression test; elastic modulus
