Drainage Channels

Drainage channels can be incorporated into your bridge joint to relieve water pressure

Plug Joint Re-Topping

Re-topping an APJ following resurfacing

Asphaltic Plug Joints do not need full depth replacement following resurfacing. Only the top layer (which was planed off) needs replacing. With the following benefits:

• Same performance: APJ performance is unaffected as the new layer fuses seamlessly with the original joint.

• Saves time: quicker operation due to lower volume of materials replaced.

• Less disruption: less work shifts are required hence fewer lane closures.

• Lower cost: partial depth replacement cheaper than full depth.

• Environmental benefits: saves replacing materials unnecessarily.


Method of re-topping

Resurfacing a bridge may typically involve the removal of 40mm of surface course by mechanical cold planer, which will also remove the top 40mm of any APJ. Instead of replacing the APJ at full depth, it is only necessary to replace the amount of joint that was removed by:

  1. Saw cut and break out the new asphalt above the bridge joint.
  2. Coat the excavated surfaces with APJ binder.
  3. Construct the new layer in accordance with the installation method statement.
