(OP)
I am looking for details on exspasion joints in concrete highway construction mainly the silcone sealents and Compression seals how they are applied and manufacturers

RE: saw cut expansion joints

Caltrans Standard Specifications have details for expansion joints in PCC paving and Bridge work.  You should be able to download them off their site.

RE: saw cut expansion joints

Also contact sealant suppliers - Sika for one.  I did a few searches (google, rediff.com, etc) and was able to pick up a lot of information on concrete sealants from there.

RE: saw cut expansion joints

qmorr....first of all, saw-cut joints are typically control joints, not expansion joints.  There's a difference.  

As for sealants, most pavement joints are either polymer modified asphaltic or urethane.  Silicone is usually not used for pavement joints.

Pre-formed EPDM or other synthetic "rubber" joint seals are used as well.

Please note that there is little need for "expansion joints" but plenty of need for control and isolation joints, all of which should be sealed against water intrusion.
