Do It Right! Lessons from the field not to be repeated

E8 joints

• When installing or re‐installing an E‐8 Joint, make sure that the joint can actually work!

• In this example, whichever side is supposed to be able to move is either locked or will break some concrete when it does move.

• Make sure the E‐8 joint is installed so it can work without breaking the sidewalks, curbs, barriers and median inlands that sit on top of it.

• Extend it all the way across the approach.
  

• Our new E‐8 joint detail calls for a drain to be installed in the bottom of the joint, and for the opening to be covered with a plate.

• Don’t let the drum from a bituminous roller roll on an unsupported concrete edge.

• You will end up with damage the contractor cannot fix.
