RAW MATERIALS AND APPLICATION Recycled Crumb Rubber in Rigid Pavements: Assessing Structural and Environmental Impact

Rubber disposal challenges include pollution from landfilling and incineration, leaching harmful chemicals, and releasing toxic emissions. This study investigates using crumb rubber in concrete to mitigate environmental impact. 

Concrete is a widely used material for constructing infrastructure worldwide. However, all infrastructure elements have a certain lifespan and will eventually fail. Rigid pavement, a common application of concrete, also has a limited lifespan, beyond which it will fail. Plain concrete provides high strength in pavement; however, it possesses low elasticity and tensile strength. In contrast, concrete with high strength and tensile strength is desired.
