29.1.3. Critical load positions

Try these first

1. 1.

   Name the three critical load positions discussed in the section.

   Hint

   Think of positions on the slab.

2. 2.

   What type of stress is found at the corner position?

   Hint

   Consider what happens at the intersection.

3. 3.

   What are the three critical load positions on rigid pavements?

   • Interior
   • Edge
   • Corner
   • Top
   • Bottom
   • Middle
   • Center
   • Side
   • Angle

   Hint

   Recall what was discussed in class.

4. 4.

   True or False: The edge position of a rigid pavement usually experiences the least stress.

   • True
   • False

   Hint

   Consider how load positions affect stress.

5. 5.

   Consider a scenario where a pavement edge is experiencing significant cracking. Propose a design modification that could alleviate these issues.

   Hint

   Think about the stress distribution relating to the location.

6. 6.

   Develop a load distribution plan for a highway segment ensuring that critical positions are reinforced; explain your choices.

   Hint

   Recall how load positions change stress impacts.
