ABSTRACT
The road system is the primary area for managing global assets. Around 95% of the world's roads are built with flexible pavements, and bitumen is the traditional binder for road materials. As a result, several road improvement strategies have been developed such as binder modification. In order to extend the useful lifetimes of previously used road pavement materials under increased traffic loads and frequency, these solutions generally rely on improving their engineering attributes. Over the past few decades, numerous studies on polymer-modified bitumen (PMBs) with much greater benefits have been conducted in relation to the functionality and service life of a road. Due to its heating and binding properties, natural rubber, one of the most widely used polymers, has been used to modify asphalt binders to increase the useful life of pavements. Pre-vulcanized latex with percentages of 7% and 9% was the type of natural rubber utilized in this investigation. Under unaged and aged conditions, tests were conducted in the laboratory using a dynamic shear rheometer with a temperature sweep. In accordance with the results of the Black Diagram for each situation, pre-vulcanized latex can be used to strengthen the asphalt binder's resistance to aging. This is demonstrated by an increase in stiffness modulus value and a decrease in phase angle. The results of the dynamic shear rheometer test showed that the addition of pre-vulcanized latex was able to increase the Complex Modulus (G*) value, decrease the phase angle, and increase resistance to rutting parameters. Pre-vulcanized latex can increase asphalt binder behavior under high temperatures, which could improve the resulting asphalt mixtures in areas with extreme climatic conditions, according to the behavior found.
