Question

Calculate the extra widening required for a pavement of width 7m on a horizontal curve of radius 200 m if the longest wheel base of vehicles expected on the road is base of vehicles expected on the road is 6.5m design speed is 65 kmph (hint:normal width of one line= 3.5)​

Answer 1

Answer:

Calculate the extra widening required for a pavement of width 7m on a horizontal curve of radius 200 m if the longest wheel base of vehicles expected on the road is base of vehicles expected on the road is 6.5m design speed is 65 kmph (hint:normal width of one line= 3.5)

Answer 2

Answer:

Step-by-step explanation: Given ,

R=200 m

v=65kmph

l=6.5m

now let us assume that n=1(for single lane)

than,

W(e)=W(m) +W(ps)

        = (n * l^2 / 2R) + ($v/9.5$*$\sqrt{R}$ )

       = 0.105 +0.0049

       =0.1099m
