Waterproofing New and Existing L.R.T. Bridge Decks

The paper presents field issues concerning the waterproofing of LRT bridge structures that are often unforeseen by the specifier. Structures built in the early 1900’s often present challenges for the field installers that require immediate decisions such as delaminated toppings, existing spent waterproofing, broken clay duct banks etc. all hindering the efficient installation of spray-applied systems. Other items to be presented include waterproofing existing structures that require work to be done while the bridge is partially in service with live third rail, active trains etc. New construction waterproofing practices on the TREX Project in Denver Colorado utilized for electric isolation of the deck, rehabilitation of Chicago Transit Authority concrete bridges done for the first time while still in service, and elevated rail structures done for New Jersey Transit, also while in service, will be presented in the form of condensed case studies.
