Abstract

The highway as one of the means of land transportation, its usefulness is felt to be increasingly important to increase the improvement of the national economy. One solution to build this road is to try the use of SMA (Stone Matrix Asphalt) asphalt pavement. Stone Matrix Asphalt (SMA) is asphalt concrete with a hot mix consisting of coarse aggregate, fine aggregate, filler material and binder (asphalt). The purpose of the study was to determine the effect of using Asbuton grain T.5/20 for asphalt pavement of the Asphalt Stone Matrix on Marshall characteristics. The materials used in the mixture are coarse aggregate from the base, fine aggregate, asphalt pen 60/70 and asbuton grain T.5/20 originating from Buton Island, Southeast Sulawesi. Marshall test for asphalt matrix asphalt on aggregate mixture with asphalt content of 4.5%, 5%, 5.5% and 6% obtained the optimum asphalt content value of 5.75%. After obtaining the optimum asphalt content, modifications were made by adding asbuton grain T.5/20 to the aggregate mixture as much as 2%, 2.5%, and 3%. The more use as a grain in the mixture, the higher the value obtained. Stability is an indicator of pavement strength under traffic loads. Asphalt Stone Matrix which is designed to obtain a large void content, while the proportion of VMA cavities obtained is getting smaller and does not meet the specification requirements.__

Abstract

Jalan Pasir Putih merupakan jalur lintas Sumatera yang berada di Kabupaten Kampar. Kepadatan lalu lintas pada ruas jalan ini sanggat tinggi, kehadiran kendaraan berat dapat menimbulkan banyak masalah seperti kemacetan, kecelakaan dan kerusakan pada lapisan perkerasan jalan. Kondisi Jalan Pasir Putih mengalami kerusakan seperti lubang, retak, bergelombang, agregat licin, alur bekas roda kendaraan dan pelepasan butiran. Kondisi ini mengakibatkan tidak lancarnya lalu lintas, keamanan dan kenyamanan pengedara menjadi terganggu, dan juga rawan terjadinya kecelakaan. Diperlukan pemeliharaan ruas jalan seperti perawatan dan perbaikan agar jalan dapat berfungsi melayani optimal sebagai mana mestinya. Pemilihan bentuk pemeliharaan jalan yang tepat dapat dilakukan dengan melakukan penilaian terhadap kondisi jalan dengan menggunakan metode Surface Distress Index (SDI). Tujuan penulisan ini adalah memperoleh nilai tingkat kerusakan jalan menggunakan metode surface Distress Index (SDI) serta dapat menentukan tipe penanganan nya berdasarkan tingkat kerusakannya. Hasil yang diperoleh yaitu bahwa kondisi ruas jalan masih baik dan diperlukan pemeliharan rutin.
