Penggunaan limbah alam abu sekam padi sebagai bahan tambah filler dalam beton aspal campuran AC-BC

Abstract

The development of infrastructure facilities in the present is increasingly rapid. This increase directly impacts the development of transportation, especially land transportation. In the development of land transportation, this requires sustainable road infrastructure which will require a lot of material as road material. To overcome the above problems, it is necessary to find alternative materials so that they can be utilized, available natural resources, one of which is rice husk ash waste in Kapanewon Godean, Sleman Regency, rice husk ash waste so that it can be used to meet these needs, research is needed so that it can be useful properly. Rice husk ash waste will be used as a filler in asphalt concrete AC-BC mixtures. As the main component in the AC-BC mixture is the largest portion of the aggregate which amounts to almost 93 to 95% of the unit weight, and the remaining amount of asphalt weight as a binder. The AC-BC mixture is usually used for the surface layer (wear layer) whose gradation is used continuous gradation that meets the specifications of Bina Marga 2010 Revision 2. This study aims; to determine the portion (%) of rice husk ash waste as a filler additive, and to find out the results of the study using, marshal test characteristics, so that the optimal asphalt content (KAO) will be produced. From the results of Job Mix Design (JMD) which will be carried out to produce Stability Value Flow, VMA; VFWA, VITM and optimum asphalt content (KAO). then from the KAO, samples are made which are added with rice husk ash waste with portions of 0%, 1%, 2%, 3%, 4%, 5% and 6%,
