Experimental Study on the Effects of Reclaimed Asphalt Pavement towards Marshall Parameters on Asphalt Course-Wearing Course

Abstract

Road pavement is one of the most important parts to provide better transportation services, for humans and or goods. To get a good road pavement, proper asphalt mixture design is needed under the required standards. In designing asphalt mixture, a large amount of materials is needed but, those materials will not be available forever. With those material limitations, alternative material is needed as a substitute, especially waste materials. One of the alternative material that could be useful is Reclaimed Asphalt Pavement (RAP). This study aims to determine the effect of RAP towards asphalt concrete mixture, based on its Marshall parameters. The method that was used in this study is a stability test, using Marshall Method. The test was carried out on asphalt concrete mixtures with four different types of RAP content, which were 25%, 50%, 75%, and 100% and with an optimum asphalt content of 5,5%. Based on these results, it was found that with the addition of RAP, it could increase the stability value of asphalt concrete, with an optimum content of RAP that can be used is 52,08%. The result shows that not only RAP could be used as an alternative, but also gives good results towards the stability value of asphalt concrete.

Oli Sisa Sebagai Bahan Peremajaan Reclaimed Asphalt Pavement (RAP) Pada Lapisan Asphalt Concrete Binder Course (AC-BC) Jalan

“…Reclaimed Asphalt Pavement (RAP) dan/atau Reclaimed Aggregate Material (RAM) diperoleh dari lapisan perkerasan yang kemudian didaur ulang pada fasilitas Hot Mix Asphalt Plant. (Geraldin & Makmur, 2020) Proses daur ulang perlu dilakukan dengan banyak pertimbangan. Beberapa lapisan perkerasan yang sudah lama perlu untuk dikeruk dan digantikan dengan material baru.…”

Study on the Suitability of Reclaimed Asphalt Pavement Aggregate (RAPA) in Hot Mix Asphalt Production

“…Many materials are required to design an asphalt mixture, but these resources are not easily available near the construction area and due to limited sources. Therefore to reduce this limitation, an alternative waste material to be substituted with virgin aggregate satisfies the standard specification suitable alternative material is Reclaimed Asphalt Pavement (RAP) (Geraldin & Makmur, 2020;Hrůza et al, 2020;Pourtahmasb & Karim, 2014).…”
