STUDI PERENCANAAN PENINGKATAN JALAN PADA RUAS JALAN JALUR LINTAS SELATAN GIRIWOYO – DUWET STA. 10+000 – STA. 15+000

Abstract

ABSTRACT The design improvement of road, and cost estimate of south path project, segmen Giriwoyo-Duwet Sta.10+000 – Sta.15+00 aims to calculate the geometric, widening , thickness of the rigid pavement, thickness of the flexible pavement overlay, and cost estimates of the improvement road project. 2017 Traffic data and California Bearing Ratio data to calculate thickness of the rigid pavement. Unit price of salary, material, and tools, and the unit price of construction job from Public Work Departement, Bina Marga of Central Java Group V used to calculate the cost estimate. The method used to design the geometric is “Tata Cara Perencanaan Geometrik Jalan Antar Kota Bina Marga 1997”. To calculate the thickness of rigid pavement with 20 years design life uses “AASHTO 1993”. Thickness of flexible pavement overlay with 20 years\xa0 design life uses “Perencanaan Tebal Perkerasan Lentur Jalan Raya Dengan Metode Analisa Komponen Bina Marga 1987” and “Panduan Analisa Harga Satuan Bina Marga 1995” to calculate the cost estimation. From the calculation of the road known that thickness of rigid pavement for improvement is 15 cm with 10 cm lean mix-concrete for subbase, and 5 cm with 2 meters roadside, flexible pavement for the surface. And the calculation of the flexible pavement overlay results is 6 cm. From the calculation the cost estimation of improvement road is IDR . 5,015,899,000 Key word : Component Analysis Method, AASHTO, Widening, Rigid Pavement, flexible pavement overlay, RAB.
