چکیده
Campuran Stone Matrix Asphalt (SMA) atau Split Mastic Asphalt, yaitu beton aspal campuran panas yang memaksimalkan penggunaan agregat kasar dan kadar tinggi kemudian diisi oleh mastik halus, filler, serat selulosa berfungsi untuk mengurangi pengaliran disebabkan tinggi. Pada penelitian ini menggunakan serabut kelapa sebagai pengganti sintetik. Penelitian bertujuan menganalisis karakteristik SMA kelapa. Dilakukan pengujian material terlebih dahulu pada kasar, aspal, sesuai prosedur SNI. Setelah itu dilakukan Marshall memperoleh Kadar Aspal Optimum (KAO). Selanjutnya dibuat benda uji kembali KAO dengan variasi yakni 0,2% ; 0,3% 0,4% terhadap berat total campuran. Diperoleh sebesar 7,25% optimum dimana nilai diperoleh 1154,85 kg (?600 kg), Sisa 96,57% (?90%). Sifat lainnya telah memenuhi Spesifikasi Umum 2018 Kementrian PUPR. Nilai Cantabro Abration Loss (CAL) 2,1% (?16%). Indirect Tensile Strength (ITS) 110,22 kPa. Pengujian (Drain-down) 0,021% (?0,3%) sedangkan tidak ditambahkan 2,09%.

متن کاملEffect of Fibers on Mixture Design of Stone Matrix Asphalt
Lignin fibers typically influence the mixture performance of stone matrix asphalt (SMA), such as strength, stability, durability, noise level, rutting resistance, fatigue life, and water sensitivity. However, limited studies were conducted to analyze the influence of fibers on the percent voids in mineral aggregate in bituminous mixture (VMA) during the mixture design. This study analyzed the e...
متن کاملEffects of Nominal Maximum Aggregate Size on the Performance of Stone Matrix Asphalt
It is well known that the performance of hot mix asphalt (HMA) in service life is closely related to a proper aggregate gradation. A laboratory study was conducted to investigate the effects of nominal maximum aggregate size (NMAS) on the performance of stone matrix asphalt (SMA). The volumetric characteristics and performance properties obtained from wheel tracking tests, permeability test, be...
متن کاملStone Mastic Asphalt Pavement Technology for the New Millennium
Since the 1960s, Stone Mastic Asphalt (SMA) pavement surfaces have been used successfully in Germany on heavily trafficked roads. Because of its excellent performance characteristics, road authorities in Germany as well as major European Countries quickly adopted SMA as a standard wearing course. As a consequence of an asphalt study tour in Europe of an American delegation in 1990, SMA test sec...
متن کاملStone mastic asphalt: assessing the effect of cellulose fibre additives
& Currently, in the UK, there is considerable interest in the fact that a German bituminous surfacing mixture known as stone mastic asphalt may possess levels of in-service performance that resist the growing incidence of premature failure experienced by traditional materials such as hot rolled asphalt. A high stone content grading requires the use of a stabilizing additive to ensure long-term ...
