Abstract

Durabilitas campuran beton aspal mempunyai pengaruh terhadap kinerja dan umur layanan suatu jalan. Durabilitas yang tinggi memberikan indikasi bahwa jalan tersebut lebih awet dan mempunyai ketahanan dari pengaruh cuaca dan air.Penelitian ini bertujuan untuk mengatahui kinerja durabilitas campuran beton aspal dengan melakukan modifikasi rendaman Marshall dan variasi suhu pemadatan. Modifikasi rendaman Marshall yang dilakukan adalah 1, 2, 4, 6 dan 8 hari serta variasi suhu pemadatan dimulaidari 90oC, 100oC, 110oC, 120 oC dan 130oC. Untuk melihat kinerja durabilitas campuran beton aspal digunakan indikator Indeks Kekuatan Sisa (IKS), Indeks Penurunan Stabilitas, yaitu Indeks Durabilitas Pertama (IDP) dan Indeks Durabilitas Kedua (IDK). Penelitian ini dilakukan di laboratorium Transportasi dan Jalan Raya Fakultas Teknik Universitas Tadulako.Dari hasil penelitian menunjukkan bahwa durabilitas campuran beton aspal masih memenuhi persyaratan bina marga yaitu nilai IKS lebih besar 75%. Durabilitas tertinggi dicapai pada suhu pemadatan 120 oC dengan lama rendaman satu hari. Nilai Indeks Kekuatan Sisa (IKS) menurun dengan meningkatnya durasi rendaman. Indeks Durabilitas Pertama (IDP) umumnya mengalami kehilangan kekuatan, kecuali pada rendaman 4 hari mengalami peingkatan kekuatan. Indeks Penururnan Stabilitas tertinggi terjadi pada suhu pemadatan 120oC. Indeks Durabilitas Kedua (IDK) pada berbagai suhu pemadatan dan variasi rendaman umumnya mengalami kehilangan kekuatan kecuali pada variasi redaman 4 hari justru terjadi penambahan kekuatan sebesar 3.4% atau naik sekitar 56,57 Kg

Abstract

One cause of the poor quality of some concrete blocks in the city of Palu is the lack of cement used in the concrete block. This is caused by the high price of cement so that income of concrete blocks maker decreases. To find a way out of these problems, a lot of waste material that can be used in the manufacture of concrete block, one of which is coal fly ash. The purpose of this activity is to introduce the use of coal fly ash in the manufacture of concrete block to business partners of  the concrete block makers in Palu city. The purpose of this activity is to make concrete block business group partners can increase their income without compromising quality concrete block produced.Activity counseling / coaching and mentoring manufacturing concrete block using coal fly ash has been done to the concrete block makers. To facilitate the implementation of the concrete block-making, each made the graduated graduated barrel of sand, cement and coal fly ash graduated. To facilitate the implementation of the concrete block-making, made barrel graduated ie graduated sand, cement and coal fly ash graduated. The composition of the mixture is introduced to the partners is 0.75 sacks of cement: 0.25 sacks of coal fly ash and ± 300 kg of sand or 1 cement barrel dose: 1  coal fly ash barrel dose and 2  sand barrels doses. The results of this activity is to get that quality of concrete blocks produced by using coal fly ash strongly increased compressive strength but does not increase the quality of concrete blocks (Remain quality II). This activity was also found that any use of the three sacks of cement will result in an additional gain of ± 130 concrete blocks. This indicates that the use of coal fly ash in the manufacture of concrete blocks to provide added value to the concrete blocks makers.
