- Determine the required structure number of the pavement based on the following information: . . ESAL= 5 million Reliability = 99% Standard deviation = 0.45 • Pi = 4.5, Pt = 2.5 . Subgrade Mr=9,000psiGiven a concrete pavement with a thickness of 8 in. (203 mm), a kvalue of 100 pei (37.1 MN/m³) doweled joints, and no concrete shoulders, determine the allowable repetitions under a 54-kip (240-kN) tridem-axle load based on erosion enteria.

- Propose 4 ways of dealing with the effect of expansive soil on construction soilsA 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 mi 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.A road of two lanes divided by a central island is at presem carrying a traffic of 1000 vehicles per day. This traffic is 80% cars and 20% trucks and their damage factors are 0.04 and 2 respectively For the design life of 15 years. the expected anual growth rate of traffic is 5.5%. Given the subgrade soil stiffness (Mg) is 7500 psi. Required a) Calculate the cumulative equivalent single axle load (ESAL) to be used in design
