Challenge Problems
Push your limits with advanced challenges
A laboratory conducted an MR test on a soil sample, yielding an MR value of 120 MPa. If another sample has an MR of 200 MPa, how might the pavement design differ between these two samples? What factors may contribute to this difference?
💡 Hint: Consider the characteristics of the two soil samples.
If engineering standards require a minimum MR of 150 MPa for certain pavement, how would you approach the design if the tested soil shows only 100 MPa? What improvements would you consider?
💡 Hint: Think about methods discussed in the chapter for improving soil strength.
