Answer Happy

1. Input the following design parameters in FPS21 (3 figures below). 2. Run the design and provide the pavement structure the software recommended. 3. Re-run the design by changing the Design Confidence Level from A to D. 4. What was the design output from the software? (Provide a screenshot of it) 5. If the software is unable to produce a design for the design parameters provided, what can you change as a designer to solve the issue, without compromising the pavement ability to withstand the expected traffic load?
For FPS21 questions, enter thicknesses with only one significant digit (example three and half inches is 3.5 not 3.50), the number of years should be entered as shown in the program (example thirteen years is 13).
