    EVALUASI STRUKTUR PERKERASAN JALAN MENGGUNAKAN DATA BERAT BEBAN KENDARAAN DARI JEMBATAN TIMBANG (Studi Kasus pada Ruas Jalan Siberida-Batas Jambi km 255+150 s/d km 256+150)

    Siberida-Batas Jambi segment has an important role to facilitate the economy of Riau Province to Jambi Province. But the street was severaly damage. For be expected to facilitate the mobility of Pekanbaru City to Jambi City, Ministry of Public Works planning road improvements. In this final project researches determine how much remaining life and to analyze pavement thickness on the Siberida-Batas Jambi segment . To evaluate the flexible pavement structure used Bina Marga 1989 method and Bina Marga 2002 method. To evaluate the rigid pavement structures used AASHTO 1993 method. According to result, there was difference between Bina Marga 1989 method and “Bina Marga 2002”method. Factors that influence these differences are different Vechicle Damage Factor, vehicle weight used, Equivalent Standart Axle Load (ESAL) and the type of layer pavement used. The rigid pavement thickness at this point requires an additional 7% of the thick original plan. In this research, the remaining life of the plan which occurred at 85,64%

    KARAKTERISTIK MARSHALL MENGGUNAKAN ASPAL RETONA BLEND 55 DENGAN VARIASI WAKTU PENGADUKAN CAMPURAN
    (2013-01-22) Nopiyanto; Sentosa Leo
    This research discusses the effect of stirring time on the Marshall characteristics of Retona Blend 55 asphalt. Marshall characteristics, namely VMA, VIM, VFA, stability, flow and Marshall Quotient were determined. The Retona Blend 55, according to accordance with the Bina Marga could improve the hot mix asphalt performance. This is particular to prevent early cracking damage for road with heavy traffic loading and high temperature. In this research, the Retona Blend 55 asphalt was made by varying the stirring time from 0.5 to 5 minutes. Initially, the Optimum Asphalt Content (KAO) by varying the stirring time was determined. From the KAO value, approximately 30 samples were produced. The samples were used for Standard Marshall and Immersion Marshall tests. Another parameter, i.e. IRS, was determined from those tests, which can be used to obtain the Optimum Stirring Time (WPO). The result shows that WPO at 1.5 minutes gave KAO of 5%. This mix was found more durable due to high IRS.

    In design asphalt hotmix, bitumen and aggregate mixing temperature and compaction temperature has an important role in determining the performance of the mixture. The temperature of mixing has a role in the process of resurfacing asphalt on aggregate, while the compaction temperature has a role in compaction density of asphalt hotmix. The best of mixing and compaction temperature, performance of the asphalt mixture will be better. Asphalt mixture designed according to Spesifikasi Umum Bina Marga in 2010. The gradient mixture is use of Laston AC-BC smooth gradation. Variation of mixing and compaction temperature is use of 160/146°C, 170/156°C, 180/166°C, 190/176°C, and 200/186°C. To find the optimum bitumen content, sample made with bitumen content of 4,5%, 5%, 5,5%, 6%, and 6,5% from the weight of sample. Each variation temperature and bitumen content is made 3 (three) of the samples. Test result and analysis Marshall of phase I acquired KAO to temperature variation II (170/156°C) is 5,55%, temperature variation III (180/166°C) is 5,5%, temperature variation IV (190/176°C) is 5,45%. Variation temperature I (160/146°C) and variation temperature V (200/186°C) did not values obtained KAO. Phase II testing is to test Marshal in the condition of KAO by the standard and immersion methods. Samples total of 18 pieces. Test result and analysis Marshall of phase II obtained recommendation mixing temperature 170°C and for compaction temperature 156°C with mixing and compaction temperature tolerance is ± 5°C. Mixing and compaction temperatures obtained after analyzing the test result of Marshall and Marshall characteristics stage II suck as test content weight of specimen, VMA, VIM, VFA, stability, flow, MQ, CAD, and IKS.
