 This study examined the physical and rheological properties of asphalt cement mixed with recycled rubber from military boots. It was found that adding rubber to the asphalt cement increased its stiffness and improved the martial stability and dynamic modulus of the resulting asphalt mixes. Additionally, this method of rubber recycling allows for proper disposal of the material while also improving the mechanical properties of the asphalt mix.
