PERENCANAAN GEOMETRIK DAN TEBAL PEKERASAN KAKU (RIGID PAVEMENT) PADA JALAN BUMBANG KECAMATAN PUJUT KABUPATEN LOMBOK TENGAH DENGAN METODE AASHTO 1993 DAN BINA MARGA 2017

This road planning was done on Bumbang Street, Central Lombok Regency. This road planning aims to build the economy in the Central Lombok Regency area. In addition, the planning of this road also aims to facilitate and provide comfort for local and foreign tourists who plan to visit the Gunung Tunak Natural Tourism Site. Therefore, geometric planning and rigid pavement thickness were carried out using the AASHTO 1993 and Bina Marga 2017 Methods. From the results of the geometric planning of the road, a horizontal alignment was obtained with the first bend located at STA 1+900 with a planned speed of 40 km/hour, a lane width of 4 meters, an outer angle of Δ1 = 42° using a Spiral Circle Spiral (SCS) bend. The thickness of the rigid pavement using the AASHTO 1993 method obtained a concrete slab thickness of 400 mm and a foundation layer thickness of 100 mm, with a total Budget Plan (RAB) of Rp 8.451.776.400. Meanwhile, the results of the Bina Marga method obtained a concrete slab thickness of 275 mm, a foundation layer thickness of 100 mm, and a drainage layer of 150 mm, with a total Budget Plan (RAB) of IDR 7.006.674.872
