Abstract

Asphalt, a popular paving material used for various applications, has taken on an increasingly significant role in promoting sustainability and environmental responsibility. One such initiative involves the incorporation of recycled rubber from scrap tires into the mix, creating a more durable and flexible pavement structure. With the growing concern over the disposal of scrap tires, using rubber waste in pavement structures is becoming a vital solution for building a more sustainable environment. By reducing the amount of non-biodegradable waste in landfills and promoting the reuse of materials, asphalt is playing a critical role in creating a more sustainable future. This experimental study sought to evaluate the cost and strength of traditional asphalt and flexible pavement with rubber crumbs, using the Marshall Stability test to assess its flow, density, and void content. The study has the following main objectives: to determine the physical and mechanical properties of Traditional Asphalt and Flexible Pavement with Rubber Crumbs; to determine the strength of Traditional Asphalt and Flexible Pavements with Rubber Crumbs; and to execute a cost analysis of Traditional Asphalt and Flexible Pavement with Rubber Crumbs and compare results. Marshall Stability test will be done on the samples of traditional asphalt and flexible pavement with rubber crumbs considering different concentrations (3%, 6%, and 9%) to estimate the strength of the pavement. The addition of rubber crumbs to asphalt mixtures resulted in lower stability values, with mixtures containing 3% rubber having a higher bulk specific gravity compared to traditional asphalt. The addition of rubber crumbs compromises the stability of the mixture, resulting in the creation of voids, lower density, and stability. As the percentage of rubber in asphalt increases, it becomes less durable, more permeable, and more susceptible to deformation.
