Randomized trial examines effects of recycled tire rubber on asphalt mixtures, suggesting optimal content for best properties.

Key Points

This research aims to investigate how recycled rubber from used tires influences the properties of asphalt mixtures and determine the optimal rubber content for performance.
Used recycled rubber at 0, 1, 2, and 3% in mixtures with limestone or basalt aggregate.
Applied Marshall mix design to find optimum binder content and evaluate the impact of rubber on asphalt mixture properties.
Conducted moisture susceptibility tests using Marshall immersion and indirect tensile strength tests.
Adding 1% rubber improved the overall qualities of bituminous mixtures made with limestone and basalt.
Both the stability and indirect tensile strength decreased with increased rubber concentration.
Basalt mixtures exhibited better stability and other properties compared to limestone mixtures at optimum binder content.
