Durabilitas Beton Aspal Jenis Ac-Wc Menggunakan Abu Arang Tempurung Kelapa Sebagai Bahan Pengisi (Filler) Dengan Variasi Waktu Rendaman
The asphalt mixture consists of aggregate, Filler, and asphalt. Commonly used materials as Fillers are cement, sand, lime, and rock ash. However, these materials have limited availability, are relatively expensive, and are non-renewable materials. One alternative to the Filler is coconut shell ash which is a waste from the coconut processing industry and is a renewable natural resource. The purpose of this study was to determine the maximum percentage of coconut shell ash for the AC-WC mixture which has a durability value and what is the value of the residual strength index of the AC-WC asphalt mixture using coconut shell ash Filler. This study used the asphalt content used in the determination of KAO of 4%, 4.5%, 5%, 5.5%, and 6%. While the Filler variations used were 0%, 2%, 4%, 6%, and 8%. This research was conducted in accordance with the General Specifications of Bina Marga 2018 Revision 2 (2020). The results of this study indicate that the mixture of AC-WC layers when soaked with variations in immersion time of 0.5 hours, 3 hours, 6 hours, 12 hours and 24 hours, the stability value and IKS decrease. The KAO value obtained was 5.60% for 0% Filler, 5.90% for 2% Filler, and 5.95 for 4% Filler. The highest stability value was obtained at 2% Filler in 0.5 hour immersion of 949.60 kg and the lowest at 4% Filler in 24 hour immersion of 228.30 kg. However, the use of coconut shell ash Filler requires more asphalt to cover the surface of the shell ash Filler.
