THE EFFECT OF RECLAIMED ASPHALT PAVEMENT (RAP) WASTE AS AN ADDED MATERIAL TO COARSE AGGREGATE IN CONCRETE MIXTURES ON THE COMPRESSIVE STRENGTH OF CONCRETE

Asphalt road maintenance aims to ensure the safety and comfort of road users. One form of asphalt road maintenance is leveling and stripping the existing road surface using a Cold Milling Machine which produces reclaimed asphalt pavement (RAP) material which has the potential to be recycled as a coarse aggregate for concrete mixtures. The research aims to utilize RAP waste as an additive to coarse aggregate in concrete mixtures with variations of 0%, 3%, 5%, 7% and 9% of the weight of coarse aggregate. The design of the fc25 MPa concrete mix refers to SNI 03-2834-2000 and uses cylindrical specimens with a height of 30 cm and a diameter of 15 cm. Testing the compressive strength of concrete at the age of 28 days used SNI 03-6429-2000 for the quality of concrete fc' 25. The results of this research are expected to provide an overview. The effect of the percentage of RAP waste addition on the compressive strength of concrete. It can be concluded that the optimal RAP waste content for the concrete mixture is 3%. With the addition of variations of 5%, 7% and 9%, the compressive strength value of the concrete decreased.
