EVALUATION OF RICE HUSK ASH AS FILLER IN ASPHALT CONCRETE-WEARING COURSE USING ASPHALT PEN 60/70 WITH ADDITION OF ASPHALT ASBUTON Maizal Kamil Department of Civil Engineering, Engineering Faculty, Syiah Kuala University Abstract The supply of stone dust as a filler and asphalt as a binder is limited, therefore it has been attempted a use of an alternative to filler and made asphalt imports. The supply problem of road material is expected to be overcome by the presence of rice husk ash as a filler and natural asphalt of Buton Island (asbuton) as a binder. This study aims to evaluate the performance of Asphalt Concrete - Wearing Course (AC-WC) mixture using rice husk ash as a filler and asphalt penetration 60/70 as binder with the addition of asbuton. The specimens made in this research are two major groups, namely: the specimens using stone dust and asphalt pen 60/70 (ABA) and the specimens using rice husk ash and asphalt pen 60/70 with the addition of asbuton (ASA). The addition was done with four variations, they were 0% (ASA 0), 5% (ASA 5), 10% (ASA 10), and 15% (ASA 15) to the total weight of the mixture. Total specimens made amounted to 75, for each type of mixture (ABA, ASA 0, ASA 5, ASA 10 and ASA 15) was made 15 specimens. Asphalt contents used were 4.5%, 5.0%, 5.5%, 6.0%, and 6.5%. Specifications used follow the standards of the Department of Settlement and Regional Infrastructure in year of 2005 by using the Marshall method.

Characteristics of mixture strength based on the condition of stability value at the average and OAC showed that ASA 10 was superior to the other mixtures. Capacity of stone dust (ABA) on the stability of the average was greater than rice husk ash (ASA 0) with the stability increased by 1.76%. Mixtures using rice husk ash as a filler with the addition of asbuton were able to compete with the mixture using stone dust as filler.

Abstract

The supply of stone dust as a filler and asphalt as a binder is limited, therefore it has been attempted a use of an alternative to filler and made asphalt imports. The supply problem of road material is expected to be overcome by the presence of rice husk ash as a filler and natural asphalt of Buton Island (asbuton) as a binder. This study aims to evaluate the performance of Asphalt Concrete - Wearing Course (AC-WC) mixture using rice husk ash as a filler and asphalt penetration 60/70 as binder with the addition of asbuton. The specimens made in this research are two major groups, namely: the specimens using stone dust and asphalt pen 60/70 (ABA) and the specimens using rice husk ash and asphalt pen 60/70 with the addition of asbuton (ASA). The addition was done with four variations, they were 0% (ASA 0), 5% (ASA 5), 10% (ASA 10), and 15% (ASA 15) to the total weight of the mixture. Total specimens made amounted to 75, for each type of mixture (ABA, ASA 0, ASA 5, ASA 10 and ASA 15) was made 15 specimens. Asphalt contents used were 4.5%, 5.0%, 5.5%, 6.0%, and 6.5%. Specifications used follow the standards of the Department of Settlement and Regional Infrastructure in year of 2005 by using the Marshall method. Optimum asphalt contents (OAC) for each mixture were 5.6% (ABA), 6.0% (ASA 0), 6.3% (ASA 5), 5.9% (ASA 10), and 5.8% (ASA 15). Characteristics of mixture strength based on the condition of stability value at the average and OAC showed that ASA 10 was superior to the other mixtures. Capacity of stone dust (ABA) on the stability of the average was greater than rice husk ash (ASA 0) with the stability increased by 1.76%. Mixtures using rice husk ash as a filler with the addition of asbuton were able to compete with the mixture using stone dust as filler.
