| Abstract | ||
| The production of rubber tires is about tens of millions annually due to the increase in the production and development of cars every year. Rubber tires need hundreds of years to decompose because one of their components is sulfur. This indicates that there is a clear environmental and economic catastrophe. The best solution is recycling rubber in different fields. The most important of which is concrete as the main backbone in the field of engineering and construction. In this study, the effect of rubber is discussed as coarse aggregate in the form of shredded rubber and as fine aggregate in the form of grinded rubber in concrete used for rigid pavement. Samples were prepared to conduct the necessary tests to study the behavior of rubberized concrete in terms of compressive, tensile strength, impact energy absorption and loading. The results showed that using ten percentage of grinded rubber was the optimal amount as the mixture had properties that were very similar to the properties of ordinary concrete regarding compressive strength, indirect tensile strength, and density. five percentage of shredded rubber caused a decrease in compressive strength, indirect tensile strength and density of sample C by about 85%, 96.5% and 97%, respectively. five percentage of grinded rubber caused a decrease in compressive strength, indirect tensile strength, and density of sample C by 69.57%, 59.6% and 93%, respectively. | ||
