ROAD GEOMETRIC FEASIBILITY IN ROAD SAGARANTEN – TEGALBULEUD KM.BDG 175 + 100

<p class="Normal1">The Sagaranten-Tegalbuleud road is a provincial road, with its geographic and topographic conditions quite complicated, the terrain quite difficult, causing not all areas to be well connected, and the reason for the low level of accessibility of this area. Therefore, determining the road geometry is an important part of driving comfort. Geometric planning focuses on horizontal and vertical alignments so that it can fulfill the basic functions of the road that provide optimal traffic flow comfort according to the planned speed. A re-survey was conducted to obtain geometric data on existing roads that did not comply with DGH standards, then it was re-planned. The results of the analysis are three bends with the Spiral-Circle-Spiral type, namely bend 9, bend 10 and bend 11 with RC = 17 m, and the slope is determined for the vertical geometrical alignment of the road. The results of this research analysis can be used as a reference for improving geometric roads so that accessibility between regions can be increased.</p>

STUDY PERENCANAAN GEOMETRIK, PERKERASAN JALAN DAN PERENCANAAN ANGGARAN BIAYA PADA JALAN RAYA KALIDAWIR – Ds. NGUBALAN Kec. KALIDAWIR

Kalidawir Highway Ngubalan Vilage which was originally a concrete rebate pavement located in the southern highland of Tulungagung City, is alternative road for local resident to go to the City area. So that the road can be sard to be guite crowded with traffic. So, here the author took the initiative to plane the road using flexible pavement. The hope for future, so it can be use as well as possible for the local Villagers. Even There included connecting roads between several villages.The method use in this planning is a method that is often used lag other planners, namely : Book Of Directorate General of Binamarga, 1970. Regulation Of Road Geometric Planning Directorate General Of Bina Marga, 1997. Procedures for planning geometric the inter city roads, The Center For Research and Development Jakarta, and use of others literature.The conclusion that can be get planning for this is, this way it is ±3.200 meter with width across 7 meter. Is available is 2 aligment horizontal PI 1 With radisius 200 meter as big as 34º33,5’5,82”. PI 2 radisius plan 150 meter as big as 34º4’22,29”. With surface course pavement = 5 cm, base course = 20 cm and sub base course = 15 cm.Keyword : Road Geometric Planning, Flexible Pavement and RAB
