Challenge Problems
Push your limits with advanced challenges
A major highway is experiencing increased traffic load leading to pavement cracking. Determine the required adjustments to compressive and flexural strengths needed to fortify the pavement for extended service life.
💡 Hint: Refer back to load requirements and typical strength values.
Assume a concrete mix is designed but fails to consider adequate shrinkage and creep resistance. Write a short report discussing potential long-term impacts and proposed revisions.
💡 Hint: Think about what uncontrolled deformation means for large-scale infrastructure.
