Day 50 - Barrier Curb Pour

The workers have the line stretched out on an offset to guide the slip forming machine down a linear path.

The machine set up on the end of the bridge ready to go.


After the wall started to be slip formed.
 The worker on the end starts to cut out the taper on the barrier wall.

The finished taper prior to placing the concrete cure.

A finished section of the wall. The slip forming machine ran really well and the concrete was good quality.

Two laborers work on finishing the concrete as it comes out of the slip forming machine.

The slip forming machine lines up on the North side of the bridge and prepares take concrete.

This picture gives a comparison between the two sides of the bridge. Kind of like looking at a before and after in real time.

The concrete in this truck went bad during the pour and was rejected by the inspector. This truck was not tested by performing an air or slump test. It was instead tested by taking the temperature. The dry concrete was hot to the touch and was 96 degrees. Three yards of concrete went on the bridge and prior to rejection and some of that concrete was removed to create a vertical start point. The slip forming machine moved ahead, rinsed off the machinery and was re-positioned.

The workers pressure washed out all of the bad concrete to clean the steel off. While they were doing this the next truck was tested and the slump was adjusted. Temperature was taken as well and read 88 degrees.

This is the section where the wall was repaired. Temporary forms were used to properly finish the wall.

This was about 45 minutes after the wall had cure sprayed on it. The workers were packing up machinery and preparing to leave.
