Roadway Joint
Roadway Joint
(OP)
I'm using a roadway expansion joint at 75' o/c. Sawcuts are at 15'. Expansion joints are for summer heat.
The roadway is for a mining project and won't see a lot of traffic, but the environment is 'less than friendly'.
Looking at two systems (both have 1" joint):
System 1:
Preformed neoprene with a 2" gap at the surface and 1/2" shoulders for support and nothing below.
System 2:
1" joint with a urethane foam backer rod and 1/2" thick Sika 1c SL recessed 1/2" below the roadway.
Any comments on which should be used, or is there a better joint.

I picked up a bit of info from Wisconson and Michigan DOT's and it was based on this that I was going to use the preformed stuff... it works well, apparently. I've got a call in to see about using an adhesive for securing the neoprene gasket. Work for the joint can wait until spring when it warms up a bit. The joint can be flushed/blown out.
The hot applied seems to be more common and I will check with local DOT's to see what is more common and why. It's also less costly to use...
