Low Porosity, High Strength Concrete for Bridge Decks
IN TR O D U CTIO N -TH E PROBLEM A few years ago a problem that previously had been a modest highway maintenance concern suddenly became a major source of dif ficulty and expense to highway departments in many areas of the coun try; including Indiana. In brief, concrete bridge decks, some new, started to spall, then delaminate, then come apart in relatively large chunks. The problem was quick...
متن کاملPrecast, Pretensioned, Post-Tensioned Concrete for Bridge Decks
The problem of concrete bridge deck deterioration on many of our newer as well as older bridges is severe, somewhat perplexing as to cause, and difficult to solve. Furthermore, the cost to highway agencies for their repair, and the cost of delay to the highway user, can be extremely large. The use of precast, prestressed concrete for bridge decks is a con cept of construction or reconstruction...
متن کاملAn Investigation on Transversely Prestressed Concrete Bridge Decks
This study is concerned with the development of design specifications for the use of transverse post-tensioning in concrete bridge decks. The ultimate goal behind this proposal is to improve the durability of concrete bridge superstructures. Experimental results from previous studies are used to validate the analytical models implemented in the development of the design specifications. It is fo...

متن کاملDelamination and concrete quality assessment of concrete bridge decks using a fully autonomous RABIT platform
One of the main causes of a limited use of nondestructive evaluation (NDE) technologies in bridge deck assessment is the speed of data collection and analysis. The paper describes development and implementation of the RABIT (Robotics Assisted Bridge Inspection Tool) for data collection using multiple NDE technologies. The system is designed to characterize three most common deterioration types ...
