Answer #1

*ANSWER :*

*THE ANSWER IS SHOWN IN BELOW HAND WRITTEN
NOTES:*

A horizontal curve is being designed for a new four-lane roadway
with 11-ft lanes. The PT is located at station 1050+20, the design
speed is 45 mph and maximum superelevation of 4%. If the central
angle of the curve is 30 degrees, what is the radius of the curve
and location of the PC and PI?

A horizontal curve with a 300 intersecting angle on a two-lane
highway with 12-ft has a 60 mph design speed. The radius for the
horizontal curve has been set to 1,250 ft. The PI is located at
station 85 + 29.14 and the normal crown on the tangent is 2%.
Determine:
a) Tangent to Spiral (TS) station,
b) Spiral to Curve (SC) station,
c) Curve to Spiral (CS) station, and d) Spiral to Tangent (ST)
station.

A reverse curve is being designed to join two roadways whose
centerlines are parallel and 72 ft apart. The two simple circular
curve components are identical. The line connecting points x and y
in the figure is 500 ft long; line x-y is tangent to the curves at
the PRC. The station of the PI1 for the first component curve
(point x) is 23+45.67
Determine:
The central angle of each component curve
The length of each component curve...

A horizontal curve on a three-lane highway with 12-ft lanes has
a PC located at station 10+00 and PT at station 13+70. The central
angle is 25 degrees, the superelevation is 4%, and 40 ft of
clearance is available between an obstruction and the centerline.
Determine the maximum safe design speed to the nearest 5 mph.

A horizontal circular curve (no spirals) has a deflection angle
of 35° 35’ 13” at a PI station of 85 + 48.53, and a degree of curve
of 5° 18’ 53”. Find the direction and distance from the PC to the
first two station stake on the curve [not counting the PC as one of
the 2].

An equal-tangent crest vertical curve is being designed for a
speed of 55 mph. The curve connects grades of 2% and -3.5% in the
direction of interest. The curve high point is at station 110+00
and has an elevation of 500 ft. What is the station and elevation
of the PVC and the PVI?

a sag vertical curve joining -3.5%and a 1.5% grades the point of
curve PC station is 188 ft with an elevation of 175 ft assume K
value for this highway is 180 determine the minimum length of the
curve L determine the station of the endpoint of the curve PT
determine the elevation of the point of intersection PL
