Ramping of Bridge Deck to Compensate for Settling

(click on thumbnails for enlarged photos)

Sequence6No1.jpg (159392 bytes) The surface of this bridge deck has settled as much as 3 inches in two directions beginning at the crown.
Sequence6No2.jpg (95518 bytes) After some grinding and pressure washing, the areas to be "ramped" are being primed with FUSION-CRETE® "pre­mix".  A stronger bond may be achieved with use of a slurry coat.
Sequence6No3.jpg (97541 bytes) A very dry mix of FUSION-CRETE® "pre­mix", Portland cement and silica sand (#30-mesh), prepared in wheel­barrows, has been applied to the bridge surface where needed and is being compacted, trowel-finished and feathered out to absolute zero.
Sequence6No4.jpg (142592 bytes) Some of the crew members can be seen continuing this process just beyond the bridge's crown where the settling has occurred in the opposite direction.
Sequence6No5.jpg (166285 bytes) This photo, taken the following day, shows the FUSION-CRETE®-fortified ramping material set up and feathered out to zero in two directions. This ramping material is flexible, fully load-bearing and extremely weather-resistant. This material will have set up sufficiently in 24 hours to open this lane for vehicular traffic.

   Estimated total time required: 8 hours
