Abstract

TAsphalt concrete mix is one type of flexible pavement layer. Asphalt concrete mixture consistsessentially of coarse aggregate, fine aggregate, filler and binder. Aggregate used may be natural orthe result of processing and can also be the artificial aggregate. While grading for asphalt concretemix is Continuously graded. This study aimed to assess the absolute density, ie density of a pavementlayer maximum value. Absolute density is needed in order to predict the quality of road pavementlayers in accordance with the variation of the number of collisions 2x75, 2x150, 2x200, 2x300 and2x400 blows. Then studied the effect of variations in the collision of the Marshall test parameters,which include density, stability, voids of mineral aggregate (VMA), voids filled with asphalt (VFWA),voids in the mix (VITM), flow and marshall qoutient. The results showed a variation of the effect ofcollisions on the value of VITM. specially for heavy traffic comparison of values obtained onvariation of the collision VITM 2x150, 2x200, 2x300 and 2x400 to VITM standard is between 50-60% (collision 2x75). These results indicate that all kinds of variations of the collision above thestandard collision will result in fatigue of materials, pavement materials become damaged as aresult. From the results of this study also obtained the optimum asphalt content for heavy traffic,moderate and mild, respectively, are 6.44%, 6.59% and 6.86%. From the results of this study alsoobtained a density value of the field whose value is based on the optimum asphalt content in successionto heavy traffic, medium and light, which is 2.35 g / cc, 2.35 g / cc and 2.36 gr/cc

Abstract

Jalan Tol adalah jalan berkapasitas tinggi yang menghubungkan kota kota yang mempunyai intensitas pergerakan tinggi sehingga harus dapat dijamin pergerakan lalu lintasnya selancar mungkin. akan tetapi tidak dapat dihindari adanya hambatan yang dapat terjadi di jalan tol , misalny kecelakaan yang mengharuskan ditutupnya sebagaian atau seluru jalurt jalan. gelombang kejut (Schock wave) didevinisikan sebagai arus pergerakan yang timbul disebabkan adanya perbedaan  kerapatan dan kecepatan lalu lintas diruas jalan. perbedaan kerapatan dan kecepatan lalu lintas diruas jalan. perbedaan kecepatan tersebut disebabakan karena adanya penyempitan. analisa gelombang kejut dapat

Abstract

Distribusi perjalanan adalah proses menghitung jumlah perjalanan yang terjadi antara satu zona dengan semua zona lainnya. Tujuan dari analisa distribusi perjalanan ini adalah untuk mengetahui jumlah perjalanan yang berasal dari kota Batu ke zona kota Batu ( intern zona ) dan dari kota Batu ke zona kabupaten Malang ( ekstern zona ). Melihat kondisi kota Batu seperti sekarang ini untuk tingkat pertumbuhan wilayah yang berbeda-beda dan pembagian wilayah atau zona yang tidak merata, maka akan menimbulkan distribusi perjalanan ( sebaran pergerakan ) yang berbeda-beda pula sehingga perlu untuk menganalisa bangkitan dan tarikan perjalanan. Analisa untuk intern dan ekstern zona menggunakan metode sintetis dengan model gravitasi karena adanya perbedaan waktu tempuh perjalanan tiap moda tidak sama. Perjalanan yang dianalisa adalah perjalanan didalam kota Batu ( intern zona ) dan perjalanan di kabupaten Malang ( ekstern zona ). Dari hasil analisa distribusi perjalanan dengan metode gravitasi jumlah perjalanan yang dihasilkan oleh masyarakat kota Batu sebesar 1746 perjalanan / hari. Untuk jumlah produksi perjalanan terbesar adalah di kecamatan Junrejo sebesar 217 perjalanan / hari. Sedangkan jumlah produksi perjalanan terkecil adalah kecamatan di Punten sebesar 49 perjalanan / hari.

Abstract

Asphalt concrete is often used as a surface layer for anticipating the heavy traffic load andhigh, it is intended to obtain a coating that is able to contribute to the measured bearing capacity.Asphalt concrete mix composed of continuously graded aggregate and asphalt binding material,where the quality of asphalt concrete in the field will be affected by manufacturing process in theAMP, distribution and compaction in field. This study aims to determine the effect of immersion inthe concrete mix to the Marshall stability value. The variation of immersion time used in this study2, 4, 6, 8, 10, 12, 24, 48 and 72 hours. The results showed that there is a very strong influence ondipping against Marshall stability value as shown by the equation Y = - 10.67 x + 228.85 and willincrease at 24 and 72 hours of immersion., While for the value of the air cavity will reach below therequirements after the age of 20 hours of immersion.Keywords: asphalt concrete mixture, Marshall stability.
