Maintenance of Traffic Issue....
(OP)
Hey all!
I have a question regarding maintenance of traffic and clearance requirements.
I have a widening project where we're maintaining traffic adjacent to a work area. The existing full-depth pavement is going to carry 4 lanes next to the work area. The work being done adjacent to the traffic will consist of saw cutting the edge of pavement (removing the shoulder) so that the roadway can be widened in the direction of the existing shoulder. A barrier will be placed (on the existing pavement) to separate the traffic and the construction zone.
My question is this: how much clearance needs to be provided between the face of barrier (on the work zone side of the barrier) and the extents of the saw cut to allow for the work crew to do the saw cutting and then complete the pavement construction? I'm currently assuming a foot will be sufficient to allow for the saw cutting of the existing pavement.
Any thoughts would be appreciated! I have checked a few state specs and standards and was unable to find any reference to this.
Thanks in advance, breaks

I am currently using 1-foot clear which may end up working. All the concrete cutting machines/saws I've seen have a blade on one side which only juts out about 3" from the body. That leaves about 9" buffer. But I will carefully consider increasing the 1-foot dimension based on what you've posted.
If anyone else has thoughts, I'd love to hear them! :)

Another option is to fill the barreir joints with stiff grout.
