PERENCANAAN LAPIS TAMBAHAN (OVERLAY) PERKERASAN LENTUR DENGAN MENGGUNAKAN METODE BINA MARGA 2017 DAN ANALISA KOMPONEN 1987 PADA RUAS JALAN MENDUT STA 0+000 – TANJUNG JAPUAN STA 2+225 KABUPATEN MAGELANG

Roads are a means of transportation that facilitates all aspects of activities. Roads have a function as a link between regions and support economic activities in a region. The Mendut - Tanjung Japuan road section is a tourism and alternative road section. The length of the Mendut – Tanjung Japuan road is 2.225 km and the width is 6.20 m. For flexible road pavement, it is necessary to analyze it in terms of costs. The method used for flexible road pavement is Bina Marga 2017 and Component Analysis 1987, as well as calculating the Budget Plan (RAB). To calculate pavement planning, data is needed in the form of CBR data, average daily traffic data (LHR), and unit price of work. From the calculation results, it was found that the thickness of the flexible pavement using the Bina Marga method was 5.5 cm and the 1987 Component Analysis method was 7 cm. Meanwhile, the calculation results show that the thickness of the flexible pavement with the surface layer using Laston 590 is 5.5 cm, the top foundation layer uses Class A crushed stone aggregate with a thickness of 20 cm, and the bottom foundation layer uses Class A Sirtu with a thickness of 17 cm and the RAB is Rp. 4.874.000.000
