“…The gradation used in this study was the Asphalt Concrete -Binder Course (AC-BC) [12], the design RAP gradations obtained from the gradation filter analysis experiment were within the upper and lower limits of the reference gradation used in the study, as result of combined gradation between the new aggregate and the RAP aggregate, was set adjusted to be line in the middle line of Asphalt Concrete -Binder Course (AC_BC) gradation [4], while the gradation slag aggregate gradation was similar to the reference gradation because slag aggregate for all filter sizes was available, as shown in Fig 1.…”

“…To rejuvenate the RAP asphalt, its characteristics are close to controlling asphalt penetration 60/70, Reclamite® rejuvenating material was used by using an approach to the softening point value and its penetration. An optimum Reclamite® content of 23% was obtained to be mixed into the RAP asphalt which was expected to restore its characteristics so that it approaches the control asphalt pen 60/70 [4].…”

“…Both for its rheological properties and its mechanistic properties, where the modification is other than improving the overall mixture, is also environmentally friendly. An example is the utilization of waste, namely the use of RAP technology which is the result of the process of pavement scraping and utilizing artificial aggregates, one of which is the slag aggregate [4,5].…”

One of the design parameters using mechanistic methods for structural evaluation of asphalt pavement is the modulus value obtained from the DSR test for asphalt modulus and UMATTA test for mixture modulus. Tests were carried out on hot mix asphalt with sixteen combinations using reclaimed asphalt pavement, EAF slag and a combination of both with a percentage of up to 30%. The result of the mixture modulus showed that the mixture with a combination of slag and Reclaimed Asphalt Pavement (RAP) gave better performance compared to the control mixture using asphalt pen 60/70 and natural aggregate. The development of the mixture modulus model was analyzed statistically with the classical assumption test and the determination of dependent variables based on the existing theoretical model. The asphalt stiffness modulus was taken from the calibrated DSR test results, asphalt mix volumetric plus the variables of the RAP and slag percentage in this study. Of the several models obtained, there were two different mixture volumetric parameters the void in mix and void filled with asphalt in the mixture both models were validated to the stiffness modulus of the mixture. From the test results obtained, the closest ratio range was the stiffness modulus of mixture model with the void in mix parameter.

“…Research on the conservation, reuse, and recycling of building materials is conducted to maximize the mechanical qualities of recycled materials, notably road pavement materials. The quality of this RAP material has undoubtedly declined throughout its service life, as evidenced by changes in gradation [12][13][14][15], asphalt aging, and mix fatigue [16]. For this reason, modifications are needed so that it can be reused as a material for constructing new road pavements [17].…”

The Effect of Recycled Material and Buton Granular Asphalt (BGA) on Asphalt Concrete Mixture Performance

Pavement recycling is an appropriate technology for constructing and restoring road pavement structures due to the limited supply and high cost of pavement materials. This study aims to improve the recycled mix's performance by replacing the fine aggregate in the recycled mix for road pavement with Buton Granular Asphalt (BGA). The percentage of recycled material (Reclaimed Asphalt Pavement/RAP) in the mixture was limited to 20% and 30% by weight of the total mixture. BGA was added by 3%, 6%, and 9% in each mixture with the RAP variation. Mixture performance was obtained through Indirect Tensile Strength (ITS) testing. The ITS test results showed that the ITS value of the mixture with RAP and BGA increased by an average of 4.7–15% compared to the mixture without RAP and BGA. The Toughness Index (TI) value increased by 3.5–19.8% with the addition of RAP. With the addition of 3% BGA, the TI value tends to increase and subsequently decrease up to 9% BGA levels. The result indicated that adding 30% RAP and 3% BGA to the mixtures improved pavement performance and could be a solution to increase the elasticity and fracture resistance of the mixture.
