Both vertical and horizontal curves on the same section of a highway are designed at the same speed. A vertical sag-curve on this highway connects G1=-7% and G2=? % grades and is 300 m long. If a horizontal curve on this highway is on a two-lane section with 3.6-m lanes, has a central angle of 43 degrees and a superelevation of 4%,
A section of highway has vertical and horizontal curves with the same design speed. A vertical sag curve on this highway connects a +1% and a +3% grade and is 420 ft long. If a horizontal curve on this highway is on a two-lane section with 12ft lanes, has a central angle of 37 degrees, and has a superelevation of 6%, what is the length of the horizontal curve?
A tangent section of highway has a -1.0% grade and ends at station 4+75 and elevation 82 ft. It must be connected to another section of highway that has a -1% grade and that begins at station 44+12 and elevation 131.2 ft. The connecting alignment should consist of a sag curve, and be designed for a speed of 50 mi/h. What is the lowest grade possible for the constant-grade section that will complete this alignment?
