4- As part of a highway interchange project, a ramp will be constructed to allow the vehicles
exit the first highway and enter the second highway. The first highway runs north-south and
the second one had a right angle to the first one (it runs east-west). Vehicles going to the
north can use this exit ramp to enter the second highway as shown in the plan view in the
figure below. The design speed in both highways is 100 km/hr. The stationing of the start of
the horizontal curve is 40+00.
a) Determine the stationing of PI and PT¶
b) The first highway has a vertical grade of +3.5% and the second highway has a grade of -
0.5%. The stationing of the beginning and the end of the crest curve are the same as the
horizontal curve. What is the elevation of the end of the vertical curve (PVT) if the
elevation of the start point (PVC) is 1500m
c) Calculate K for the vertical curve

- 8- A granular pavement with thin bituminous surfacing is going to be constructed in a rural area and it is estimated that the average annual daily traffic will be 21,000 vehicles per day. The road will have 3 lanes in each direction. The survey data from the existing roads close to that area shows that 15% of the vehicles in the traffic stream are heavy and the rest are light. However, no details of heavy vehicle types are given. It is also estimated that the annual growth factor is 3.2%.

The retaining structure is made of wood planks supported in the horizontal direction on vertical steel piles (HP sections). The HP piles shape of an H and are typically used for piles. The section properties of these sections (A, I, S, etc…) are given in Part 1 of the AISC steel manual. The spacing of the supporting HP piles is 20ft. The height of the piles is 15 from top of the pile to top of the footing. The height of the water table from the top of the footing is 9 ft as shown in the elevation in Fig. 4. The pile height and soil properties and the earth pressure distribution behind the retaining structure are shown in Fig. 5.
