Problem 4. A section of a two-lane highway has 12-ft lanes and a design speed of 75 mi/h. The section contains a vertical curve and a horizontal curve. The vertical curve connects a-2.5% grade and a +1.5% grade. The PVT of this vertical curve is at station 36 + 50. The PC of the horizontal curve is located 294 ft before the PVC of the vertical curve. The horizontal curve has superelevation of 8% and central angle of 38 degrees....

Problem 1 (15vpts) A proposed highway has two tangents of bearings N 75° 54' 36" E and N 53° 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 78.00 ft. The Pl is at station 65+43.21. Determine: (a) The external angle of the curve (A) (b) The radius of the curve (d) The station of the PC (f) The...

In order to design safe
high-speed entrance and exit ramps, highway engineers need to know
about the force of friction and the maximum speeds that motorists
can navigate these ramps. Suppose the coefficients of friction
between rubber tires and asphalt are µs = 0.35 for static friction
and µk = 0.25 for kinetic friction. You are the highway engineer
charged with construction of a new freeway exit ramp. (a) Make a
free-body diagram showing all of the forces acting on...

1) Determine the minimum radius of curvature required for a 60 mi/hr design speed with a 0.06 superelevation rate and 64 degree of curvature (A). Find the locations for T.C. and C.T. if the P.I. is located at 500+00. In addition, calculate T, L, M, E, and C. 2) Prepare a table of chords and deflection angles for staking out a 600 foot radius circular curve with a deflection angle of 60 degrees. Give values for every full station and...
