Corps chooses precast panels for lock rehab
Article Abstract:
The US Army Corps of Engineers has discovered that pre-cast concrete panels may be used for lock chamber repairs instead of cast-in-place concrete. After conducting studies on the material, they employed this new method during the restoration of the Troy Lock and Dam located at the Hudson river in New York. The advantages of pre-cast concrete include improved weather resistance, better cost-efficiency, more manageable winter construction and high concrete quality. It also facilitates faster work flow because it lessens on-site labor, maximizes production output and is easy to install and handle.

Conference promotes polymer concrete rehab
Article Abstract:
The market for highly filled resin (HFR) systems has increased by 7% to 10% per year in the 1980s and is now a $250 million a year industry. Intertech Corp Pres Hugh Olmstead made the observation in an Intertech-sponsored world conference on HFR and polymer concrete held on Mar 1992 in New Jersey. Participants, however, focused on polymer concrete. Its advocates cited its potential for use as highway overlays for its skid resistance, low permeability, effective bonding and fast curing. At the moment, only few a states use polymer concrete on their roads, probably because of its high cost.

Deck modules speed work, cut bridge rehab cost
Article Abstract:
Value engineering and modular construction cut at least $100,000 off a $4.2 million renovation of a 600-foot steel cantilevered truss bridge built in 1915 in New York state. The contractor, Harrison and Burrowes, also speeded up the work by months by using quickly-installed exodermic deck modules to replace the bridge decking.
