ABSTRACT

Road damage has been a major problem in the mobilization of people and goods. Therefore, it is essential to develop a pavement technology capable of autonomously self-healing when subjected to damage. To achieve this, a thorough evaluation of its characteristics and performance at the laboratory scale becomes necessary. As the length of roads utilizing asphalt materials continues to increase annually, there is an urgent need to explore alternative binders to fossil-based materials, favoring mining products found on Earth's surface. This study addresses this concern by combining oil asphalt binder and rock asphalt from Buton Island. This study combined oil asphalt binder and rock asphalt from Buton Island, as an effort to switch the use of binder from fossil materials to binder from mining products on the Earth's surface. The paper offers comprehensive insights from characteristical investigations, Marshall parameters, and stiffness modulus analyses, aiming to assess the impact of varying percentages of calcium Alginate capsules. The Marshall test results demonstrate a decrease in Marshall stability parameters with the addition of calcium Alginate capsules. However, this decrease remains within the acceptable threshold, along with parameters like VIM, VMA, VFB, and flow. Moreover, the test results indicate that calcium Alginate capsules contribute to increased cavity formation and improved melting in the mixture. Tensile test results do not directly show the effect of stiffness to the mixture containing calcium Alginate, but this mixture has good visco elastic properties when it gets repeated loads. The decrease in performance observed in the Marshall test revealed that the stiffness modulus also declines as the percentage of calcium alginate capsules increases.
