Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.

A long segment of suburban freeway is to be designed on level terrain. The level segment, however, is followed by a 4.5% grade, 2.0 miles in length. If the DDHV is 2,500 vehicles per hour with 15% trucks (standard mix), how many lanes will be needed on the (A.) Upgrade, (B.) Downgrade, (C.) Level terrain segment to provide for level of service C? Lane widths and lateral clearances may be assumed to be 12 feet and 6 feet, respectively. Ramp density is expected to be 1.0 ramps per mile. The PHF is 0.92. Good weather, no incidents, no work zones, and regular users of the facility may be assumed.

The 2 southbound lanes of a four-lane (i.e. 2 lanes each direction) urban freeway are 12 ft wide. There is at least 6 ft of lateral clearance on the right side of the outer/right lane. There are two ramps within the influence area (i.e. within 3 miles upstream and 3 miles downstream of the center of the segment. What is the estimated FFS (mph)? Provide the answer to the nearest tenths.
Determine the value of PTSF for a 6-mile two-lane highway in rolling terrain. Traffic data are as follows: • Volume = 1600 veh/h (two-way) • Percent trucks = 14% • Percent RVs = 4% • Peak hour factor = 0.95 • Percent directional split = 50 - 50 • Percent no-passing zones = 50
