Feasibility of crack free reinforced concrete bridge deck from materials composition perspective: a state of the art review

Mahdi AREZOUMANDI

Frontiers of Structural and Civil Engineering 2015, Volume 9, Issue 1,   Pages 91-103 doi: 10.1007/s11709-015-0274-1

Abstract: Early age cracking on bridge deck has been the subject of many studies for years. Cracking is a major concern because it leads to premature deterioration of structures. Millions of dollars spent to repair the cracked bridge decks each year. To design an appropriate mixture for crack free bridge deck, it is important to study previous researches. This paper presents a comprehensive literature review of the performance of different materials compositions as well as methods have been used to reduce and control bridge deck cracks. Different material compositions and methods are discussed in terms of their performances as well as advantages and disadvantages.
