Percobaan filler abu vulkanik akan dijadikan campuran aspal dalam perkerasan untuk menghasilkan perpaduan yang baik antara agregat kasar, agregat halus, aspal, dan filler..Berdasarkan standar campuran beraspal panas di Indonesia, kinerja campuran diperoleh dari pengujian Marshall, pengujian Marshall Immersion, pengujian Modulus Resilien UMATTA, dan pengujian Fatigue dengan kontrol tegangan. Sementara itu kinerja campuran aspal dingin diperoleh dari pengujian marshall dan pengujian marshall immersion. Pengujian Campuran Aspal Panas dan campuran aspal dingin dilakukan setelah mendapatkan nilai KAO dari filler abu batu (standar).


Kinerja campuran hasil uji Marshall campuran aspal panas memberikan nilai Stabilitas Marshall yang tertinggi diraih oleh filler abu vulkanik Gunung Sinabung dengan 1453 kg. Hasil pengujian perendaman Marshall diraih oleh filler abu semen memberikan nilai tertinggi sebesar 94,24%. Untuk Campuran dingin nilai stabilitas tertinggi diraih oleh filler abu vulkanik dengan 640 kg. Hasil pengujian perendaman Marshall diraih oleh filler abu semen memberikan nilai tertinggi sebesar 81,03%. Hasil pengujian Modulus Resilien pada campuran filler abu vulkanik Gunung Sinabung memberikan nilai sebesar 5282 MPa pada temperatur 25°C, dan 652 MPa pada temperatur 45°C, yang merupakan nilai tertinggi dari campuran filler abu semen. Hasil pengujian Fatigue pada campuran aspal dengan filler abu semen memberikan nilai sebesar 94320 cycles pada tegangan 1400 Kpa, 68590 cycles pada tegangan 1276 Kpa, dan 45260 cycles pada tegangan 1199 Kpa, yang merupakan nilai tertinggi dari campuran filler abu vulkanik Gunung Sinabung.


Secara umum, Dilihat dari Spesifikasi Bina Marga 2010 Revisi III (Min. 90%), hasil pengujian menunjukkan bahwa penggunaan filler abu vulkanik terhadap campuran panas lebih tahan (durable) terhadap nilai modulus resilien. Namun tidak lebih kaku (stiffness) daripada filler abu semen. Untuk hasil pengujian terhadap campuran dingin, penggunaan filler abu vulkanik masih mampu meningkatkan nilai stabilitas yang ditentukan oleh Asphalt Institute MS-14 dengan nilai stabilitas Minimal 500 dan Nilai Indeks kekuatan sisa marshall minimal 75%.

Deskripsi Alternatif :

The experimental of volcanic ash as filler, will be used as a mixture of asphalt in pavement to produce a good combination of coarse aggregate, fine aggregate, asphalt and filler. Based on the standard of hot mix asphalt in Indonesia, mixed performance is obtained from Marshall test, Marshall Immersion test, Resilient Modulus test UMATTA, and Fatigue testing with controlling of stress. Meanwhile, the cold mix asphalt performance was obtained from Marshall testing and Marshall immersion testing using MC-250 cutback asphalt, which is combination between a asphalt pen.60/70 with kerosene. HMA and Cutback Asphalt could be do if to get a KAO value from filler of fly ash (standard). Cement ash is also tested the performance of HMA and Cutback Asphalt as a comparison result for Volcanic ash as filler.


The mixed performance of HMA Marshall test gives the highest Marshall Stability achieved by volcanic ash filler of Sinabung Mountain with 1453 kg. The results of Marshall immersion testing achieved by cement ash filler gave the highest value of 94.24%. For Cutback Asphalt the highest stability value is achieved by a volcanic ash filler with 640 kg. The results of Marshall immersion testing achieved by cement ash filler gave the highest value of 81.03%. For the Resilient Modulus test results on the volcanic ash mixture of Mount Sinabung gave a value of 5282 MPa at 25°C, and 652 MPa at 45°C, which is the highest value than the cement filler mixer. For the Fatigue test results on HMA with cement ash filler give 94320 cycles value at stress level 1400 Kpa, 68590 cycles at stress level 1276 Kpa, and 45260 cycles at stress level 1199 Kpa, which is the highest value than the volcanic ash of Mount Sinabung.


Generally, seen from Bina Marga specification (IKS at least 90%) the test results show that the using of volcanic ash filler for Hot mix asphalt AC-BC, is more durable. But no more stiffness (stiffness) than filler cement ash. For the test results against the cutback asphalt MC-250, That the using of volcanic ash filler has been able to increase the stability value determined by Asphalt Institute MS-14 with Minimum stability value 500 kg and the Marshall residual strength (IKS) value of at least 75%.
