Abstract :

Background and Objective: The expansion of the construction industry and many environmental problems have aimed to move towards recycling technology in the optimal management of building materials. The economic and environmental benefits of the recycling industry have made researchers conduct numerous experiments to optimize new recycled materials. In this regard, rubber waste has received special attention as one of the environmental problems. For this purpose, in the current research, the management of industrial recycling of products has been examined by modeling using multi-criteria decision-making method, in order to select the best options for crumb rubber concrete products

Material and Methodology: In the first stage, according to the opinion of experts and professors of environmental and civil engineering, among the 23 best criteria in 5 groups of economic, environmental, technical, management and insulation factors were selected. In the second stage, by taking the first questionnaire based on the Likert scale of statistical analysis with SPSS software, 17 criteria and 5 influential options were selected. Then, in the third stage, multi-criteria decision-making modeling using AHP hierarchical analysis method with EC software was used based on the data of the second questionnaire for the final ranking of concrete products.

Findings: Based on the results, the final prioritization of concrete products was determined with weights equal to 0.235, 0.219, 0.196, 0.179, and 0.17, respectively, and asphalt crumb concrete, guardrail, and partition panel were placed in the top priorities.

Discussion and Conclusion: Based on the results of the research in three stages, in all aspects of the investigation, including experimental studies and the first stage questionnaire and modeling, regarding the best products, Crumb Rubber Asphalt Concrete product as The best product was selected and based on the business model, it was possible to produce the product on an industrial scale.
