2. A six lane divided highway is to be designed to replace an existing highway. The present AADT (both directions) of 6000 vehicles is expected to grow at 5% per year. Assume SN = 4 and p = 2.5. The percent of traffic on the design lane is 45%. Determine the design ESAL if the design life is 20 years and the vehicle mix is: Passenger cars (4.44kN/axle) = 60% 2-axle single unit trucks (22.2kN/axle) = 30% 3-axle single unit trucks (31.11kN/axle) = 10%

A four-lane rural freeway segment has a 510 m grade length of 2% upgrade followed by a 630 m grade length of 3%. The freeway has 3.4-m lane, 1.5m left-shoulder lateral clearances and interchanges spaced at every 25 km. During the peak hour, there are 6% trucks, 2% buses, 2% recreational vehicles and the rest are passenger cars. Driver population adjustment is determined to be 0.90, peak hour factor is 0.90 and the BFFS is 110 km/h. At present, the freeway operates at capacity during the peak hour in the direction in question. If an additional 3.4 m lane is introduced, and all other factors stay the same, what will be the new level of service?
The predicted traffic mix of a proposed four-lane urban non-interstate freeway is as follows. Passenger cars = 78% Single-unit trucks: 2-axle, 5,000 lb/axle = 12% 2-axle, 9,000 lb/axle = 4% 3-axle or more, 23,000 lb/axle = 3% Tractor semitrailers and combinations: 3-axle, 20,000 lb/axle = 3% The projected AADT during the first year of operation is 3,900 (both directions). If the traffic growth rate is estimated at 3 percent and the CBR of the subgrade is 7.5, determine the depth of a full-asphalt pavement (in inches) using the AASHTO method and n = 20 years. The resilient modulus of the asphalt (EAC) is 320,000 lb/in². Assume m, for the subgrade is 1 and the percent of traffic on the design lane is 42 percent, pt = 2.5, and SN = 4. Use a reliability level of 90 percent, a standard deviation of 0.45, and a design serviceability loss of 2.0. Assume the design lane factor f is 0.42. (Use single-axle load equivalency factors for 2-axle vehicles and tandem-axle load equivalency factors for…

A 6-lane urban freeway is suggested to be designed with the following data: F.ADT = 45000 vpd, design hour factor= 0.12 and directional split = 65%. Rolling terrain, 10% trucks, 5% buses, 6% Rvs, PHF is 0.91 and all traffic are commuters. Then based on the HCM 2000 procedure, the equivalent passenger- car hourly flow rate is about

A two-lane, one-way, rural freeway segment is being designed to service a demand volume of 4,000 vehicles per hour. The PHF is expected to be 0.95.

A six-lane divided highway is to be designed to replace an existing highway. The present AADT (both directions) of 5,300 vehicles is expected to grow at 5 percent per annum. Assume SN = 4 and pt = 2.5. The percent of traffic on the design lane is 45 percent. Determine the design ESAL if the design life is 20 years and the vehicle mix is as follows. (Assume the contribution of passenger car traffic to the total ESAL is negligible. Use single-axle load equivalency factors for 2-axle and 3-axle trucks.) Passenger cars (1,000 lb/axle)=59%2-axle single-unit trucks (5,000 lb/axle)=25%3-axle single-unit trucks (7,000 lb/axle)=16%
An existing rural 4-lane highway is to be replaced by a 6-lane divided expressway (3 lanes in each direction). Traffic volume data on the highway indicate that the AADT (both directions) during the first year of operation is 24,000 with the following vehicle mix and axle loads. Passenger cars = 50 percent 2-axle single-unit trucks (12,000 lb/axle) = 40 percent 3-axle single-unit trucks (16,000 lb/axle) = 10 percent The vehicle mix is expected to remain the same throughout the design life of 20 years, although traffic is expected to grow at a rate of 3.5 percent annually. Using the AASHTO design procedure, determine the minimum depth of concrete pavement required for the design period of 20 years.
