Challenge Problems
Push your limits with advanced challenges
You conduct a Plate Bearing Test on a site and get settlements of 1.2 mm, 1.5 mm, and 1.3 mm under successive loads of 160 kg, 180 kg, and 170 kg, respectively. Calculate the average modulus of subgrade reaction.
💡 Hint: Don’t forget to sum the settlements and divide by the number of readings!
A construction project finds that the anticipated modulus calculated isn't sufficient for expected traffic loads. Suggest alternative methods to improve subgrade support.
💡 Hint: Think about both materials and structural changes that can enhance support.
