Durable long lasting concrete is a basic requirement. Long
lasting concrete like the precast and prestressed types are
seen to be one way for transportation agencies to increase
durability. Considering the case of the use of high strength
concretes, and the pretreated variety, it can be said that they
help reinforce with more strength. Secondly they also have
very much reduced permeability, which is a requirement in a
bridge deck. High strength and reduced permeability also
means increased durability[4]. However high strength
concretes might fail when compared to the precast and
prestressed types because these are seen to show signs of
early cracking. Early cracking is possible because of selfdesiccation.
