Nama : Rizal Zubad FirdausiSemester : V (lima)NIM : 07.10203.020Mata Kuliah : Geometrik Jalan Raya

Data lapangan: D1 1000 m D2 700 m D3= 500 m D4= 1000 m

PI 1Diketahui: V = 70 Km/jam e= 0.1 Lebar Jalan standart = 2 x3.75 m

9 f= 0.15

Jenis = Full Circle 0.02

Ditanya : Geometrik Jalan tersebut?

Jawab :R min =

127(e+f)

= 156.21 = 157

D max = 181913.53 (e+f)

= 9.17

Lc min = t . v

= 6 x 70 x 1000

3600= 116.67 m

Rc = Lc min . 360 Dari tabel 4.7 bina marga diperoleh:

Ls = 60 m= 743.1 e = 0.04

Tc == 58.48

Ec =

= 2.3

Lc =180

= 116.67

Landai Relatif = Lebar jalan . (e normal + e)

Ls= 0

Data lengkung Circle dari jalan tersebut adalah:V = 70
