Asphalt Concrete Pavement

In the construction of asphalt mixture pavement, there are many paving construction procedures, high requirements for machinery and personnel, unreasonable technology and so on. In this paper, the millimeter-scale 3D automatic paving control technology of asphalt mixture pavement is studied with an engineering example. From the analysis of the test results in the later stage of construction, it can be seen that the technology has achieved the goal of high precision paving, and the successful application of the technology provides valuable reference experience for similar asphalt concrete pavement construction in the future.

<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%.

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>

Asphalt Concrete Pavement

Focusing on the severity of asphalt concrete pavement crack, the optimization analyzing finite element model(FEM) of typical asphalt overlay pavement was developed to address reflective cracking, in which the analysis of traffic-loading response were concentrated on the stress-intensive areas close to the joints or cracks. The FE sensitive analysis, evaluating the influence of pavement construction parameters, including modulus and thickness of pavement courses, is useful to establish comprehensive model of overlay pavement construction.

Fatigue crack is one of the main road damage forms of asphalt pavement structure, and serious impact the asphalt pavement performance and service life. Asphalt mixture has typical viscoelastic,and can get Burgers model and viscoelastic parameters form creep test. Using finite element method of fracture mechanics, simulation under dynamic loading, research crack extending behavior of common asphalt concrete pavement and mixed with 0.2% of sisal fiber asphalt concrete pavement. From the results, it can find out that when mixed with sisal fiber, the anti-fatigue cracking performance is obvious enhancement.

The high temperature of asphalt concrete pavement decreases its bearing capacity, thus leading to serious rutting. In this paper, a coated thermal resistance/heat reflection pavement construction technology with a coating of 2-3mm on the asphalt pavement is mainly introduced, which can reflect and prevent sunshine and reduce the surface temperature of asphalt pavement for the purpose of preventing rutting. In addition, the coated thermal resistance/heat reflection paving method is introduced, which is of certain reference to the promotion and application of coated thermal resistance/heat reflection pavement.
