STUDY OF RECLAIMED ASPHALT PAVEMENT MATERIALS WITH WASTE ENGINE OIL AS REJUVENATOR USING DYNAMIC SHEAR RHEOMETER

CIVIL ENGINEERING

Developing countries requires large quantities of materials, where continues development of infrastructure is necessary, requirement of construction materials is continuously increases exponentially. The transportation development can be profitable by using the recycled aggregates acquired form existing pavement practices. When an asphalt pavement needs to be replaced, the existing pavement is removed. This acquired material, known as reclaimed asphalt pavement (RAP), is then used with new asphalt roads. The reuse of RAP needs to be treated before using it with new asphalt. RAP are weathered during their course of use. Repeated exposure of RAP to ultraviolet rays and moisture deteriorates the properties of the aggregates and binders. It is adequate to treat RAP before using with new asphalt. This study focuses on the possibility of using waste engine oil as a rejuvenator for the higher percentage of reclaimed asphalt pavement that could meet the increasing demand in a more sustainable way. Testing was conducted for asphalt binder testing and laboratory mixture testing. Asphalt binder testing consisted of dynamic shear rheometer
