Abstract

One important part of the asphalt mixture is the aggregate gradation. Characteristics of concrete asphalt mixtures such as stability and flow are strongly influenced by aggregate gradations. The purpose of this study is to obtain the Marshall characteristics of asphalt concrete mixtures using artificial aggregates with BBA (Bitumineux pour chausées Aéronautiques) gradation and FAA (Federal Aviation Administration) gradation. Artificial aggregates that have been obtained in previous studies are the materials that will be used in this study. From the results experiment it was found that the asphalt concrete mixture using BBA gradation had the highest stability compare to the stability of FAA gradation with value of 2055,9 Kg and 2039,1 Kg respectively. The highest flow value in the BBA gradation mixture was 3.63 mm while the FAA gradation mixture was 3.60 mm. For Marshall Quotient values, the mixture of BBA gradation is 566.8 Kg / mm and FAA gradation mixture is 571.8 Kg / mm. Salah satu bagian penting dalam campuran beraspal adalah gradasi agregat. Karakteristik campuran aspal beton seperti stabilitas dan flow sangat dipengaruhi oleh gradasi agregat. Tujuan penelitian ini untuk mendapatkan karakteristik Marshall campuran aspal beton yang menggunakan agregat buatan dengan gradasi BBA (Beton Bitumineux pour chausées Aéronautiques) dan gradasi FAA (Federal Aviation Administration). Agregat buatan yang sudah diperoleh dalam penelitian sebelumnya menjadi bahan yang akan digunakan dalam penelitian ini. Dari hasil pemeriksaan didapat bahwa campuran aspal beton yang menggunakan gradasi BBA mempunyai nilai stabilitas tertinggi yaitu sebesar 2055,9 Kg, sedangkan nilai stabilitas campuran gradasi FAA sebesar 2039,1 Kg. Nilai flow tertinggi pada campuran gradasi BBA yaitu sebesar 3,63 mm sedangkan campuran gradasi FAA sebesar 3,60 mm. Untuk nilai Marshall Quotient campuran gradasi BBA sebesar 566,8 Kg/mm dan campuran gradasi FAA sebesar 571,8 Kg/mm.

Abstract

The type of damage to the pavement layer is cracking and permanent deformation. The mechanism of cracking in the pavement layer occurs because of the tensile force at the bottom of the pavement layer due to the wheel load of the vehicle. One parameter of a mixture to achieve strength and durability as needed is the relationship of stress and strain which shows the stiffness of a mixture. Indirect Tensile Strength is a method used to show the stiffness of a mixture. As infrastructure development in Indonesia continues to increase, the availability of natural aggregate materials is decreasing. One of the uses of geopolymer can be used as artificial aggregates to replace the depleted natural aggregates. The purpose of this study was to review the stiffness modulus of concrete asphalt mixture with the use of artificial aggregates made from geopolymer by using open gradations of BBA (Beton Bitumineux pour chausees Aeronautques). From the test results using the Dynapave UTM30 tool at 20 °Celsius and 60 °Celsius, stiffness modulus values of the asphalt mixture are 3542 MPa and 147 MPa. The increase in temperature causes a decrease in the stiffness modulus value of 96%, so that the increase in temperature will be accompanied by a decrease in the stiffness modulus.
