Abstract:
This study aims to improve the physical and mechanical properties of porous
asphalt by using the inorganic compound titanium dioxide, a versatile compound that is
the fifth most abundant substance on the earth's surface. Porous asphalt is a sustainable
and effective solution for managing stormwater and controlling urban flooding, but
improving performance while maintaining stormwater management capabilities is also a
major challenge. To address this issue, titanium dioxide has been introduced into asphalt
mixtures at various concentrations of 1%, 1.5% and 2% to study the effects of titanium
dioxide on pavement strength, stability, durability, rutting, abrasion, and wear resistance.
tear. Deformation due to changing traffic loads. This study evaluates the physical,
chemical, and thermal properties as well as permeability and porosity properties of
modified asphalt through laboratory experiments and extensive mechanical testing.
Research results show that the addition of titanium dioxide at a concentration of 2%
significantly improved the overall performance of porous asphalt by 10.7% to contribute
to urban flood control activities.
