9:381 LTE Problem 1 A crest vertical curve is to be designed to join a +2% grade with a-2% at a section of a two-lane highway. Determine the minimum length of the curve if the design speed of the highway is 60 mph and SL. Assume that a-9.34 ftsec' and that the perception-reaction time is 2.5 sec.

A sag vertical curve will connect two tangents, a -3% grade and a +5% grade, 800 ft apart. The ravine in which the sag curve will be situated needs to be built up. The elevation of the curve at its deepest point must be at elevation 168.00 ft or higher to clear a major pipe installation. If the PVC is at station 00 + 00.00 with an elevation of 176.20 ft, determine the location of the deepest point of the...

7. A sag vertical curve connects a-4.75% grade and a +3.75% grade. The PVI is at station 45+90.00 at an elevation of 611.00 ft. The design speed is 50 mi/h. Determine the minimum length of the vertical curve using the AASHTO method ("K" factors). Round the minimum length up to the next 10 ft multiple for design of the vertical curve and associated calculations. Using this length, determine: The station and elevation of the PVC The station and elevation of...

2. Given a sag vertical curve connecting a -1.5% grade with a +2.5% grade on a rural arterial highway, use the rate of vertical curvature and a design speed of 70 mi/h to compute the elevation of the curve at 100 ft stations if the grades intersect at station (475+00) at an elevation of 300.00 ft. Identify the station and elevation of the low point.

A +2.8 percent grade intersects a -5.0 percent grade at station 2+ 800 and an elevation of 200.0 m. Design a parabolic curve to join the two grades. Calculate the centerline elevation every 40.0m starting from “VPC” to “VPT”, and the station and elevation of the highest point on curve. The speed limit on the road is 100 km/hr.

Sag Vertical Curve) An existing highway-railway at-grade crossing is being redesigned as grade separated to improve traffic operations. The railway must remain at the same elevation. The highway is being reconstructed to travel under the railway. The underpass will be a sag curve that has an initial grade of -2% and a final grade of 2%. The PVI of the sag curve will be centered under the railway (a symmetrical alignment). The sag curve design speed is 45 mi/h. How...
