Challenge Problems
Push your limits with advanced challenges
Calculate the total ESAL for a truck with three axle configurations, where axle 1 has 60 kN with 5000 passes, axle 2 has 100 kN with 2000 passes, and axle 3 has 140 kN with 1000 passes. The standard is 80 kN.
💡 Hint: Use the EALF formula for each axle and then sum up the results.
Discuss and calculate how introducing a new truck with an axle load of 200 kN would change the EALF previously established for standard load assessments.
💡 Hint: Evaluate the comparative assessments and model based on the new EALF.
