Background: Number of used tires is increasing every day and the accumulation of such waste is a serious problem in terms of environmental protection and in terms of delay and deposition (End-of-LifeTires, 2019). Over the last twenty years the study of new ways to use products from recycled tires has been intensified. When developing new products, it is important to investigate how certain properties of the materials used change. According to the available literature, different variants of material composition and processing approaches have been investigated (Kowalska, Chmielewski, Guleira & Dutta, 2017; Zaoiai, Makani, Tafraoui & Benmerioul, 2015).
Objectives: The aim of this work, based on the evaluation of an experiment using a mathematical model, is to determine the required structure of the material. The possibility and correctness of using the linear model was determined.
Methods/Approach: The experiment was conducted to check the magnitude of the deformation depending on the stress.
Results: Based on the obtained results, the accuracy of the applied linear model and the influence of individual factors on the results of the experiment were evaluated.
Conclusions: Mathematical linear model estimation refers to the determination of quantitative parameters in the structure of a material. If the required deformation is defined or acceptable, other material parameters can be determined with some accuracy.
