Abstract

In an effort to increase the strength of mixed asphalt concrete structure ( AC-WC ) in addition to the use of hot asphalt mixture with new specification, the selection of material type used is very important. In addition to asphalt, both coarse and fine aggregates and fillers are one component in a pavement construction that has a large role. Therefore further research is needed on the influence of temperature variation and percentage of filler fly ash to the modulus of r esilien which is good so that it can be applied and able to overcome the damages. In this research is divided into 3 (three) stages namely (1) the selection of materials; (2) the preparation of the specimen; (3) research and data analysis. Asphalt concrete mixed test (AC-WC) showed that Asphalt Optimum (KAO) content with 5.5% asphalt content with VIM value of 3.70%, VMA of 19.00%, Stability of 1,152.93 kg, Flow of 2.78 mm and MQ of 417.39 kg/mm. The result of mixed asphalt concrete (AC-WC) asphalt with filler fly ash test showed that the optimum mixture content was 7% filler content with VIM value 4,21%, VMA 19,21%, Stability 1326.10 kg, Flow of 3.69 mm and MQ of 360.13 kg/mm.


Dalam upaya meningkatkan kekuatan struktur campuran beton aspal lapisan aus (AC-WC) selain perlu adanya penggunaan campuran beraspal panas dengan spesifikasi baru, pemilihan jenis material yang digunakan adalah sangat penting. Selain aspal, agregat baik kasar maupun halus serta filler adalah salah satu komponen dalam suatu konstruksi perkerasan jalan yang mempunyai peranan besar. Oleh karena itu diperlukan penelitian lebih lanjut mengenai pengaruh variasi temperatur dan prosentase filler fly ash terhadap modulus resilien yang baik sehingga dapat diterapkan dan mampu mengatasi kerusakan-kerusakan. Dalam penelitian ini terbagi dalam 3 (tiga) tahapan yaitu (1) tahapan pemilihan bahan; (2) tahap persiapan benda uji; (3) tahap penelitian dan analisis data. Hasil pengujian campuran aspal beton lapis aus (AC-WC) menunjukan bahwa Kadar Aspal Optimum (KAO) yaitu dengan kadar aspal 5,5% dengan nilai VIM sebesar 3.70%, VMA sebesar 19,00%, Stabilitas sebesar 1.152,93 Kg, Flow sebesar 2,78 mm dan MQ sebesar 417,39 Kg/mm. Hasil pengujian campuran aspal beton lapis aus (AC-WC) dengan penggantian filller fly ash menunjukan bahwa kadar campuran optimum yaitu dengan kadar filler 7% dengan nilai VIM sebesar 4,21%, VMA sebesar 19,21%, Stabilitas sebesar 1326.10 Kg, Flow sebesar 3,69 mm dan MQ sebesar 360.13 Kg/m.
