<p align="center"><strong>Abstrak</strong></p><p class="11daftarpustaka"> </p><p>Campuran beraspal panas adalah kombinasi antara agregat yang dicampur merata dan dilapisi oleh aspal. Bahan penyusun dari campuran AC-BC hampir sama dengan bahan penyusun campuran aspal beton lainnya yaitu agregat halus, agregat kasar, <em>filler </em>dan aspal, yang membedakan adalah komposisi gradasi masing-masing lapisan. Penelitian ini membahas mengenai pengaruh penggantian Filler pada perkerasan jalan aspal beton AC-BC. Adapun tujuan dari penelitian ini adalah untuk mengetahui bagaimana pengaruh penggunaan<em> </em>Abu batu karang<em> </em>sebagai <em>Filler </em>dan pasir besi sebagai agregat halus terhadap karakteristik Marshall terhadap campuran Aspal AC-BC (<em>Asphalt Concrete – </em><em>Binder Course</em>) terhadap stabilitas dengan metode Spesifikasi Umum Bina Marga 2010 Revisi 3, Benda uji yang didapatkan dari kadar aspal optimumnya adalah sebesar 6,2 % dan untuk benda uji penambahan variasi yang digunakan adalah abu batu karang dan pasir besi  25% - 50% -75% - 100%. Adapun Hasil dari pengujian di laboratorium di dapatkan hasil grafik yang naik turun, peningkatan nilai stabilitas didapat dari penambahan kadar variasi 25%, 50%, 75%, dan mengalami penurunan pada penambahan 100% variasi pasir besi dan abu batu karang, sedangkan nilai Density meningkat pada variasi 100%,  VMA , VIM dan FLOW dengan penambahan<em> </em>pasir besi dan abu batu karang menurun pada variasi 50%-100%, sedangkan VFA, MQ  terjadi Peningkatan yang tidak terlalu signifikan pada variasi 100%. Maka dapat disimpulkan variasi penambahan abu batu karang dan dan pasir besi  sebagai pengganti <em>filler</em> dan penganti agregat halus memenuhi spesifikasi bina marga 2010 revisi 3.</p><p><em> </em></p><p>Kata Kunci:<em> Spesifikasi 2010 rev 3, </em><em>Filler, Agregat halus,</em><em> </em><em>Parameter Marshall</em><em></em></p><p align="center"><strong> </strong></p><p align="center"><strong> </strong></p><p align="center"><strong>Abstract</strong></p><p class="11daftarpustaka"> </p><p class="11daftarpustaka">Hot asphalt mixture is a combination of aggregates that are mixed evenly and coated with asphalt. The composition of AC-BC mixture is almost the same as the composition of other concrete asphalt mixers, namely fine aggregate, coarse aggregate, filler and asphalt, the difference is the gradation composition of each layer. This study discusses the effect of Filler replacement on AC-BC asphalt concrete pavement. The purpose of this research is to find out how the influence of the use of coral ash as fillers and iron sand as fine aggregate on the Marshall characteristics of the Asphalt Concrete - Binder Course asphalt mixture against stability with the General Reinforcement 2010 Revised 3 General Specifications method, The specimens obtained from the optimum asphalt content is 6.2% and for specimens the addition of variations used is rock ash and iron sand 25% - 50% -75% - 100%. As for the results of testing in the laboratory graph results get up and down, increasing the value of stability obtained from adding levels of variation 25%, 50%, 75%, and decreased in the addition of 100% variation of iron sand and rock ash, while the Density value increased at variations of 100%, VMA, VIM and FLOW with the addition of iron sand and coral ash decreased at a variation of 50% -100%, while VFA, MQ occurred a not too significant increase at 100% variation. Then it can be concluded that variations in the addition of coral ash and iron sand as a substitute for filler and substitute for fine aggregate meet the specifications of the 2010 revision 3.</p><p class="11daftarpustaka">Keywords: 2010 rev 3 specification, filler, fine aggregate, Marshall parameters</p>

This article introduces the application of the MDD(Multi-depth Deflectometer) in the asphalt concrete concrete pavement. By analyzing its work principle, MDD was calibrated to get the real response of the pavement structure and reveals its true condition. It also introduces the details of the MDDS installation and illustrates the analysis of the typical response date, which is helpful for the further application of MDD in the asphalt concrete pavement design.

Drucker-Prager linear elastic-perfectly plastic model and the associated flow rule, a numerical simulation study has been conducted on the layered asphalt concrete pavement structure, using the 2D axisymmetric finite element method (FEM). Pursuant to empirical equation of the stability, cohesion and internal friction angle of asphalt concrete, and in line with experimental test subjects on pavement material and pavement performance, the impact of mechanical parameters of each layer of asphalt concrete on the road surface deflection and the evolution law of plasticity in each structural layer under standard axle load has been studied.
