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 To maintain the level of service of a road needs a proper evaluation method, both structural and functional evaluations. Austroads method 2011 is a method that has been accommodating resistance to fatigue cracking, which is a reference for use in Indonesia. In this study the Austroads method 2011is examined whether if it can be implemented in Indonesia. Structural evaluations conducted based on data obtained from the Falling Weight deflectometer while functional evaluation conducted based on data obtained from the roughness NAASRA tool. The results indicate that the DSAR7 value obtained by the Austroads 2011 method is quite identical to the value generated by the CESAL Bina Marga method. The implementation of Austroads 2011 method for road conditions in Indonesia needs to consider several things, namely pavement structure modeling, types of vehicles, as well as the "presumptive" values in the Austroads 2011 method for determining the amount of design traffic, material properties, deflection measurement process, and the value of IRI. Keywords: road service, pavement, structural evaluation, functional evaluation, deflection Abstrak Untuk mempertahankan tingkat pelayanan suatu jalan dibutuhkan suatu metode evaluasi yang tepat, baik evaluasi struktural maupun evaluasi fungsional. Metode Austroads 2011 adalah salah satu metode yang telah mengakomodasi ketahanan terhadap retak lelah, yang menjadi acuan untuk digunakan di Indonesia. Pada studi ini dikaji apakah Metode Austroads 2011 dapat diterapkan di Indonesia. Evaluasi struktural dilakukan berdasarkan data lendutan yang didapat dari alat Falling Weight Deflectometer sedangkan evaluasi fungsional dilakukan berdasarkan data roughness yang diperoleh dari alat NAASRA. Hasil penelitian ini menunjukkan bahwa nilai DSAR7 yang diperoleh dengan Metode Austroads 2011 cukup identik dengan nilai CESAL yang dihasilkan oleh Metode Bina Marga. Penerapan Metode Austroads 2011 untuk kondisi jalan di Indonesia perlu mempertimbangkan beberapa hal, yaitu pemodelan struktur perkerasan, pembagian jenis kendaraan, serta nilai-nilai “presumtif” dalam Metode Austroads 2011 untuk menentukan jumlah lalulintas desain, sifat material, proses pengukuran lendutan, dan nilai IRI. Kata-kata kunci: pelayanan jalan, perkerasan, evaluasi struktural, evaluasi fungsional, lendutan

Dasar dari metoda analisis struktur memerlukan perhitungan tegangan dan regangan pada suatu perkerasan yang merupakan respons struktur terhadap kondisi pembebanan tertentu.Didalam solusi analitis tegangan dan regangan tersebut, seringkali dilakukan simplifikasi dengan mengambil beberapa asumsi, seperti : kondisi isotropik dari setiap lapis perkerasan, kondisi interface antar lapis sangat kasar serta beban yang diterima struktur perkerasan yang diakibatkan roda kendaraan mempunyai arah vertikal. Asumsi diatas akan menghasilkan nilai tegangan, dan regangan yang belum sesuai dengan kenyataan. Oleh karena itu diperlukan pengembangan asumsi kearah faktor-faktor tersebut terutama faktor tipe pembebanan. Untuk variasi pembebanan ada 4 jenis pembebanan yang mungkin terjadi yaitu beban arah vertikal yang saat ini secara luas dipakai pada analisis struktur perkerasan lentur, beban vertikal yang dikombinasikan dengan tegangan geser arah radial memusat akibat ‘cengkeraman' ban, beban vertikal yang dikombinasikan dengan tegangan arah horizontal akibat percepatan dan pengereman kendaraan dan beban verikal yang dikombinasikan dengan momen akibat kendaraan membelok. Dengan menggunakan kriteria fatigue dapat dianalisis bahwa jenis pembebanan arah vertikal yang dikombinasikan dengan arah radial menghasilkan jumlah repetisi yang tiga kali lebih besar dibandingkan dengan pembebanan vertikal saja. Dalam pengertian umur perkerasan, pembebanan dengan mengabaikan beban arah pusat radial akan mengakibatkan perkiraan rencana umur perkerasan yang berlebihan. Penerapan model ini pada Jalan Tol Jakarta-Cikampek menunjukkan bahwa pengabaian beban geser radial memusat akan menyebabkan kerusakan jalan yang terlambat diantisipasi dengan program overlay akibat estimasi umur rencana yang lebih dari perkiraan.

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.
