Concept explainers

Design of pavements

Pavement is a structure that is made up of different layers such as sub-base course layer, base course layer, binder course, and a surface course formed with different materials such as gravel, above the subgrade soil constructed to act as a path or carriageway enabling the movement of vehicles. The surface of the pavement should possess characteristics such as adequate friction, light reflection, and drainage. The pavements are classified based on structural design into rigid pavements, flexible pavements, composite pavements, and unpaved pavements. The process of determining a suitable pavement type, its constituent layers, and its thickness is called pavement design.

Step by step solutionProblem 3: A four-lane freeway (two lanes in each direction) operates at capacity during the peak hour. It has 11-ft lanes, 5-ft shoulders, and there are 3 ramps within 3 miles upstream of the segment midpoint and 3 ramps within 3 miles downstream of the segment midpoint. The freeway is on rolling terrain and has 10% heavy vehicles with a PHF of 0.9. It is known that 15% of the AADT occurs in the peak hour and the directional factor is 0.7. Determine: (a) Heavy vehicle adjustment factor(b) Free-flow speed(c) Capacity(d) Volume-to-capacity ratio(e) Density and LOS(f) AADT(g) What is the highest possible value of the heavy vehicle adjustment factor? (h) If the volume exceeds capacity, what is the LOS? Note: No need to show calculations for (g) and (h).
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 section of a two-lane rural highway is to be realigned and replaced by a four-lane highway with a full-depth asphalt pavement. The AADT (both ways) on the existing section can be represented by 750 ESAL. It is expected that construction will be completed 5 years from now. If the traffic growth rate is 2 percent and the effective CBR of the subgrade on the new alignment is 9.0, determine a suitable depth of the asphalt pavement (in inches) using the AASHTO method. Take the design life of the pavement as 20 years. The resilient modulus of the asphalt (EAC) is 450,000 lb/in. ². Assume m; for the subgrade is 1 and the percent of traffic on the design lane is 45 percent. Use a reliability level of 90 percent, a standard deviation of 0.45, and a design serviceability loss of 2.0. 8.25 inches
A six lane divided highway is being designed for a current AADT of 6000 vehicles with a growth rate of 5% and a design life of 20 years. If the vehicle mix is 60% passenger cars (2 kips), 30% 3-axle single unit truck (12 kips) and 10% 3-axle tandem trailer (30 kips). The pavement has a terminal serviceability index (pt) of 2.5 and Structural Number (SN) of 5. Determine the design ESAL?
