Abstract The condition of bonding between asphalt pavement layer can influence the behaviour of pavement structure in supporting vehicle loading. In strong bonding condition, the adjacent pavement layers will act together to support pavement loading and the other way in weak bonding condition the layers will act independently with the result that stress in every layer of pavement become higher and will decrease pavement life consequently. This study described the investigation of bonding condition using teorethical model and laboratory test. Those are developed using CIRCLY5-SAP2000 Program and Modified Direct Shear Test respectively. The results shown that there is the range of bonding parameter which starting from weak bonding until full bonding using theoretical and laboratory model. Futhermore the analysis shown that ignoring bonding condition between pavement layer will become one of factors which cause early damage in pavement structure.Keywords : Bonding, Direct Shear Test, SAP2000, CIRCLY5

Abstract Bioasphalt are asphalt produced from non-food ingredients which can be renewed. In addition to being used as a binder in asphalt mixture, since it is derived from lignin-containing biomass, bioasphalt also has the potential as rejuvenator for a mixture containing reclaimed asphalt pavement as well as additive for warm mixed asphalt technology due to its rheological properties that can reduce mixing temperatures up to 20°C. America, Europe, Japan and Australia have started their research on bioasphalt since the last few years. Indonesia itself can produce bioasphalt from coconut shells, but the research related to bioasphalt potency in paved mixture technology is still very limited. To prove the potential of bioasphalt, research needs to be done by evaluating the performance of bioasphalt available in Indonesia as a rejuvenator in Hot Mix Asphalt containing Reclaimed Asphalt Pavement and as an additive for warm mixed asphalt technology. Keywords: bioasphalt, hot mix asphalt, reclaimed asphalt pavement, warm mix asphalt Abstrak Bioaspal adalah aspal yang dihasilkan dari bahan nonmakanan dan dapat diperbaharui. Selain dapat digunakan sebagai bahan pengikat campuran beraspal, karena berasal dari biomassa yang mengandung lignin, bioaspal juga berpotensi sebagai bahan peremaja untuk campuran yang mengandung reclaimed asphalt pavement serta sebagai bahan tambah untuk teknologi campuran beraspal hangat karena sifat reologinya yang dapat menurunkan temperatur pencampuran hingga 20°C. Amerika, Eropa, Jepang, dan Australia telah memulai penelitian terhadap bioaspal sejak beberapa tahun belakangan. Indonesia sendiri sudah dapat menghasilkan bioaspal yang berasal dari tempurung kelapa, hanya saja penelitian terkait potensi bioaspal pada teknologi campuran beraspal masih sangat minim. Untuk membuktikan potensi bioaspal tersebut, perlu dilakukan penelitian dengan mengevaluasi kinerja bioaspal yang ada di Indonesia sebagai bahan peremaja pada campuran beraspal panas yang mengandung reclaimed asphalt pavement dan sebagai bahan tambah penurun temperatur pencampuran untuk teknologi campuran beraspal hangat. Kata-kata kunci: bioaspal, campuran beraspal panas, reclaimed asphalt pavement, campuran beraspal hangat

Abstract Material constraints and increasing demand for road construction materials have resulted in high construction costs and road rehabilitation, so alternative materials are needed, such as recycled asphalt and potential waste utilization, such as steel slags. This study is a literature study, with the aim of evaluating and controlling the performance of asphalt mixtures using Reclaimed Asphalt Pavement and steel slag, as a substitute for aggregate. The Reclaimed Asphalt Pavement material generally has aging which causes an increase in stiffness during the structural life and reduced adhesion to asphalt. This can be prevented by steel slag material, which has a rough surface and texture, so as to prevent cracks due to internal friction of the mixture. The overall use of Reclaimed Asphalt Pavement materials and steel slag can improve mixture performance and resistance to fatigue. Keywords: asphalt mixture, reclaimed asphalt pavement, steel slag, flexible pavement Abstrak Keterbatasan material dan meningkatnya permintaan material konstruksi jalan menyebabkan tingginya biaya pembangunan maupun rehabilitas jalan, sehingga diperlukan material alternatif, seperti daur ulang aspal dan pemanfaatan potensi limbah, seperti slag baja. Penelitian ini merupakan suatu kajian literatur, dengan tujuan melakukan evaluasi dan pengendalian kinerja campuran beraspal yang menggunakan Reclaimed Pavement Asphalt (RAP) dan slag baja sebagai bahan pengganti agregat. Material RAP umumnya telah mengalami penuaan yang menyebabkan peningkatan kekakuan selama umur struktur dan sifat adhesi terhadap aspal berkurang. Hal ini dapat dicegah oleh material slag baja, yang memiliki permukaan dan tekstur yang kasar, sehingga dapat mencegah terjadinya retak akibat gesekan internal campuran. Penggunaaan material RAP dan slag baja secara keseluruhan dapat meningkatkan kinerja campuran dan ketahanan terhadap kelelahan. Kata-kata kunci: campuran beraspal, reclaimed pavement asphalt, slag baja, perkerasan lentur

Abstract Fatigue cracking is the most dominant type of distress in flexible pavements. In this research, an experimental study was conducted to determine the fatigue life and flexural stiffness curves for several types of asphalt mixtures commonly used in Indonesia, namely Asphalt Concrete Wearing Course, Hot Rolled Sheet, and Stone Mastic Asphalt. The fatigue life test was carried out using a four-point loading device with strain control. This study shows that the asphalt content for Asphalt Concrete Wearing Course mixture is in the range of 5.63% to 6.50%, for Hot Rolled Sheet mixture is in the range of 7.40% to 8.49%, and for Stone Mastic Asphalt mixture is the range of 6.60% to 7.31%. This study also produced a fatigue curve, with the higher the strain applied to the flexible pavement, the shorter the fatigue life of the flexible pavement, and vice versa. Keywords: flexible pavement; asphalt mixture; fatigue life; four-point loading Abstrak Retak lelah merupakan jenis kerusakan yang paling dominan pada perkerasan lentur. Pada penelitian ini dilakukan kajian eksperimental untuk menentukan umur lelah dan kurva kekakuan lentur pada beberapa jenis campuran beraspal yang umum digunakan di Indonesia, yaitu Asphalt Concrete Wearing Course, Hot Rolled Sheet, dan Stone Mastic Asphalt. Pengujian umur lelah dilakukan dengan menggunakan alat four-point loading dengan kontrol regangan. Studi ini menunjukkan bahwa kadar aspal untuk campuran Asphalt Concrete Wearing Course berada pada rentang 5,63% hingga 6,50%, untuk campuran Hot Rolled Sheet berada pada rentang 7,40% hingga 8,49%, dan untuk campuran Stone Mastic Asphalt berada pada rentang 6,60% hingga 7,31%. Pada studi ini juga dihasilkan kurva umur lelah, dengan semakin tinggi regangan yang diberikan pada perkerasan lentur, semakin pendek umur lelah perkerasan lentur tersebut, demikian pula sebaliknya. Kata-kata kunci: perkerasan lentur; campuran beraspal; umur lelah; pengujian empat titik
