Abstract

Evaluation of the conditions of Jalan Soekarno Hatta using PCI method shows that the condition of "Good" both on rigid and flexible pavement is most common, with the percentage of each of them being 61.9% and 21.6%. Meanwhile, by using PSI method, the most commonly found are "Fair" conditions both in rigid and flexible pavement, with the percentage of each being 81% and 48,9%.  Using the SDI method on the flexible pavement, the most commonly found is the condition of "Medium" with a percentage of 65,9%. The parametric analysis between PCI and PSI on rigid pavement produced R2 = 0.0548 with a regression equation of PCI = 96,66 "“ 3,9352 x PSI, while PCI and PSI correlation on flexible pavement produced R2 = 0.8163 with regression equation of PCI = 27,673 + 16,848 x PSI., and PCI and SDI correlations on flexible pavement yields R2 = 0,8653 with a regression equation of PCI = 94,663 "“ 0,4462 x SDI The non-parametric analysis between PCI and PSI on rigid pavement produced a correlation coefficient of 0.043, while the PCI and PSI values on flexible pavements produced a correlation coefficient of 0.397, and PCI and SDI on flexible pavement produced a correlation coefficient of 0.492. Based on the two methods, both parametric and non parametric analysis, the relationship between PCI and SDI was considered better than the PCI and PSI relationship because it produced an R2 value and a greater correlation coefficient Evaluasi kondisi Jalan Soekarno Hatta dengan menggunakan metode PCI menunjukan bahwa yang paling banyak di temukan adalah kondisi "Good" baik pada perkerasan kaku maupun perkerasan lentur, dengan persentase masing masing adalah 61,9 % dan 21,6 %.

Abstract

The application of warm mix asphalt technology to reduce mixing and compaction temperatures has a weakness in decreasing the performance of mixture and is more sensitive to high temperatures. This is influenced by the type of additives and the warm mix asphalt technology used. The purpose of this study is to determine the optimum percentage of Rediset®LQ used and the amount of temperature drop in the type of Pen 60/70 asphalt mixture. Determination of the percentage of optimum use of the Rediset®LQ was carried out by using mixed workability analysis. The results of the warm mix asphalt test are then compared with the control HMA, the volumetric value that is close to the control HMA is considered to have equivalent workability. The variation of the use of the Rediset®LQ is 0.25% to 0.75% with a variation of the mixture temperature reduction of 15 ºC, 30 ºC, and 45 ºC. The results showed that the optimum percentage of using Rediset®LQ on asphalt pen 60/70 was 0.5% with a large reduction in mixing temperature and optimum compaction of 30 ºC. Evaluation of the resilient modulus value of the WMA mixture is equivalent to the HMA mixture at low, medium, and high temperatures. Based on the analysis, the Warm Mix Asphalt Concrete Binder Course with Rediset®LQ additive, also lower mixing and compaction temperature, is suitable for use on pavement layers.

Abstract

Abstract One way to be developed to overcome challenges in providing flexible pavement materials is to apply the green roads principle by reusing some or all of the old road pavement material or Reclaimed Asphalt Pavement (RAP) as a material for new road pavement, which if reused will affect the performance of the mixture, such as decreasing the level of durability and premature pavement damage, so an effort must be made to improve the performance of the recycled material, namely by adding full extracted Asbuton and rejuvenating materials. The RAP material was obtained from scratching the asphalt of the Jagorawi Toll Road. The mixture used was asphalt concrete-binder course (AC-BC) layer using 30%, 40%, and 50% RAP material, using full extracted Asbuton at 6%, and Nichireki rejuvenating material. Then, on mixtures with RAP material, Marshall Test, Resilient Modulus test with UMATTA, and resistance to fatigue with four points loading test with strain control were conducted. The use of RAP material with modified asphalt in the form of an addition of full extracted Asbuton into the Pen 60/70 Asphalt can increase the asphalt stiffness. Marshall test results showed that a mixture with 6% full extracted asbuton content and 0% RAP material content (A6RAP0) gave the highest stability value. The results of the Resilient Modulus test showed that the mixture with 6% full extracted asbuton content and 50% RAP material content (A6RAP50) gave a high Resilient Modulus value at a test temperature of 45oC. The results of the fatigue resistance test showed that the mixture with 6% full extracted asbuton content and 50% RAP material content (A6RAP50) at a strain level of 300 µε gave the longest fatigue life. Keywords: Reclaimed asphalt pavement (RAP), full extracted asbuton, asphalt concrete -binder course, modified asphalt, resilient modulus, fatigue life. Abstrak Salah satu cara dikembangkan untuk mengatasi tantangan dalam penyediaan material perkerasan lentur adalah menerapkan prinsip greenroads dengan memanfaatkan kembali sebagian atau keseluruhan material perkerasan jalan lama atau Reclaimed Asphalt Pavement (RAP) sebagai material untuk perkerasan jalan yang baru, dimana jika digunakan kembali akan mempengaruhi kinerja dari campuran seperti penurunan tingkat durabilitas dan kerusakan dini perkerasan, sehingga harus dilakukan suatu upaya untuk memperbaiki kinerja dari material daur ulang tersebut, yaitu dengan penambahan Asbuton murni dan bahan peremaja. Material RAP didapatkan dari hasil garukan aspal Jalan Tol Jagorawi. Campuran yang dipakai adalah Laston Lapis AC-BC menggunakan kadar material RAP sebanyak 30%, 40%, dan 50%, dengan penggunaan Asbuton murni sebesar 6%, serta bahan peremaja Nichireki, dan kemudian selanjutnya pada campuran dengan penggunaan material RAP dilakukan pengujian Marshall, Modulus Resilien dengan alat UMATTA dan ketahanan terhadap kelelahan (fatigue) metode four points loading test dengan kontrol regangan. Penggunaan material RAP dengan aspal modifkasi berupa penambahan Asbuton murni kedalam Aspal Shell Pen 60/70 dapat meningkatkan kekakuan aspal. Hasil pengujian Marshall menunjukkan campuran dengan kadar Asbuton murni 6% dan kadar material RAP 0% (A6RAP0) memberikan nilai stabilitas tertinggi. Hasil pengujian Modulus Resilien menunjukkan campuran campuran dengan kadar Asbuton murni 6% dan kadar material RAP 50% (A6RAP50) memberikan nilai Modulus Resilien yang tinggi pada temperatur pengujian 45oC. Hasil pengujian ketahanan terhadap kelelahan menunjukkan campuran dengan kadar Asbuton murni 6% dan kadar material RAP 50% (A6RAP50) pada regangan 300 µε memberikan umur kelelahan yang paling panjang. Kata-kata kunci: Reclaimed asphalt pavement (RAP), Asbuton murni, laston lapis antara, aspal modifikasi,  modulus resilien, umur kelelahan.

Abstract

Abstrak The compaction of the asphalt mixture using the Superpave Gyratory Compactor according to AASHTO T312-14 requires compaction at gyration angle of 1.16°±0.02°. This study is intended to evaluate the gyration angle requirements by analyzing the performance of the Resilience Modulus and fatigue strength (fatigue) in the SMA mixture using variations in the rotation angle (0.82°, 1.16°, and 1.16°). 1.5°). The compaction of the asphalt mixture using Marshall compactor was also carried out as a comparison to the performance of the mixture with the variation of the angle of gyration. The compaction of the SMA mixture using the Marshall method has a smaller VIM and a larger VMA compared to the SGC method with a gyration angle of 1.16° and 1.5°. The VIM value range of the Marshall method is 3-5% while the SGC method is 4%. This affects the value of the optimum asphalt content in each method. With increasing angle of gyration will influence to Resilient Modulus of  SMA at 25°C increase by 26% as well. The SMA compacted using the SGC method resulted in a higher MR value than the Marshall method. The results of the fatigue test using Four Point Loading showed that the SMA mixture compacted by the SGC method with a gyration angle of 0.82° is higher than that which was compacted using the Marshall method. Furthermore, it can be recommended compaction of SGC with a gyration angle of 1,000,  100 gyration, a pressure of 600 kPa, and a speed of 30 rpm which results in better performance than Marshall compaction. SGC compaction is better in workability, density, and achieve volumetric targets than Marshall compaction. Kata Kunci: SMA, superpave gyratory compactor (SGC), angle of gyration, resilient modulus, fatigue. Abstract Pemadatan campuran beraspal menggunakan Superpave Gyratory Compactor sesuai AASHTO T312-14 mempersyaratkan pemadatan pada sudut 1,16°±0,02°. Penelitian ini dimaksudkan untuk mengevaluasi persyaratan sudut putaran ini dengan menganalisis kinerja Modulus Resilien dan kuat lelah (fatigue) pada campuran SMA dengan menggunakan variasi sudut putaran (0,82°, 1,16°, dan 1,5°). Pemadatan campuran beraspal menggunakan pemadat Marshall juga dilakukan sebagai pembanding terhadap kinerja campuran dengan variasi sudut putaran tersebut. Pemadatan campuran SMA menggunakan metode Marshall memiliki nilai VIM yang lebih kecil dan VMA lebih besar dibandingkan dengan metode SGC sudut putaran 1,16° dan 1,5°. Rentang nilai VIM metode Marshall yaitu 3 – 5% sedangkan metode SGC sebesar 4%. Hal ini yang mempengaruhi nilai kadar aspal optimum (KAO) pada masing-masing metode. Nilai Modulus Resilien (suhu 25°C) pada campuran SMA menunjukkan bahwa semakin besar sudut putaran maka nilai MR akan semakin meningkat sebesar 26%. Campuran SMA yang dipadatkan dengan metode SGC Spesifikasi AASHTO menghasilkan nilai MR yang lebih tinggi dibandingkan metode Marshall Spesifikasi Umum Bina Marga Tahun 2018. Hasil pengujian fatigue dengan Four Point Loading menunjukkan bahwa campuran SMA yang dipadatkan dengan metode SGC sudut putaran 0,82° menghasilkan nilai umur kelelahan lebih tinggi dibandingkan dengan yang dipadatkan dengan metode Marshall Spesifikasi Umum Bina Marga Tahun 2018. Dengan variasi sudut putaran ini dapat direkomendasikan pemadatan SGC dengan sudut putaran 1,000, sebanyak 100 putaran, tekanan 600 kPa, dan kecepatan 30 rpm yang menghasilkan kinerja yang lebih baik dari pemadatan Marshall. Pemadatan SGC lebih mudah dalam workability, keseragaman kepadatan, serta pencapaian target volumetrik dibandingkan pemadatan Marshall. Keywords: SMA, superpave gyratory compactor, sudut putaran, resilient modulus, fatigue.

Abstract

Abstrak Nano teknologi merupakan suatu teknologi rekayasa pada material kedalam ukuran atom atau molekul. Salah satu sifat unik dari nano material yaitu memiliki fraksi permukaan yang cukup besar dan kinerja permukaan yang cukup tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh dari penambahan nano material pada campuran aspal panas lapis aus (AC-WC). Material nano yang digunakan pada penelitian ini adalah material silika yang berasal dari pasir kuarsa Bangka Belitung yang kemudian diproses menjadi nano silika oleh Balai Besar Keramik Bandung. Aspal yang digunakan pada campuran adalah aspal pen 60/70 produksi Pertamina. Penggunaan material nano silika sebagai subtitusi filler dapat mengurangi penggunaan kadar aspal yang mana dapat dilihat dari nilai kadar aspal optimum yang dihasilkan pada campuran dengan variasi 1%, 2%, 3% nano silika jika dibandingkan campuran beraspal konvensional. Selain itu, penggunaan alat pemadat yang berbeda memberikan pengaruh terhadap kepadatan yang dihasilkan pada campuran dengan penambahan nano silika. Hal tersebut terlihat bahwa kepadatan yang dihasilkan oleh alat pemadat superpave gyratory compactor (SGC) menghasilkan kepadatan yang lebih kecil dibandingkan dengan alat pemadat marshall. Kata – kata Kunci: Campuran Aspal, Filler, Kadar Aspal, Nanosilika Abstract Nanotechnology is an engineering technology on materials into atomic or molecular sizes. One of the unique properties of nanomaterials is that have a large surface fraction and high surface performance. This study aims to determine the effect of the addition of nanomaterials on hot mix asphalt (AC-WC). The nano material used is silica from Bangka Belitung quartz sand which is processed into nano silica by Balai Besar Keramik Bandung. The asphalt used in the mixture is asphalt pen 60/70 produced by Pertamina. Nano silica is used as a filler substitution so that is can reduce the asphalt content which could be seen from the optimum asphalt content value with mixed variations of 1%, 2%, 3% nano silica when compared to conventional asphalt mixtures. In addition, using different compactor has an effect on nano silika mixture asphalt density. It can be seen that density value from superpave gyratori compactor (SGC) is lower than marshall compactor. Keyword: Asphalt Mixture, Asphalt Content, Filler, Nanosilica

Abstract

Each motor vehicle produces a variety of noise. For areas which directly intersects the highway this noise has a considerable impact. The volume of motorcycles and private as well as public vehicles all have a significant effect on noise. From all analytical calculations, the largest equation was obtained one the second day of research on the second point of Sound Level Meter 2 (SLM2). The calculation is that y = 0,0158x – 1,0176. This equation indicates that if there is no decrease in the volume of the motorcycle, the noise level on the SLM2 is 65.21 dBA. If there is an increase or decrease in the volume of a motorcycle, it will have a significant effect on noise. The second largest equation was obtained on the second day of the research at the third point from the Sound Level Meter 3 (SLM3) and the calculation of the equation is y = 0,01 – 6,074. The purpose of the above equation is that if there is an increase in the volume of a motorcycle, the noise on the SLM3 is 60.840 dBA. According to the findings, there was a reduction in the number of motorcycles during the Covid-19 pandemic, because schools were closed and students did not attend school.
