In order to increase the crack resistance, durability and tensile stress resistance of conventional concrete it is a general practice nowadays to use fiber reinforced concrete. Macro synthetic fibers such as polypropylene are the latest improvement over traditional steel fibers in in this regard. The enhanced tensile stress resistance, crack resistance and energy absorption of structural members casted using macro fiber reinforced concrete makes it the best suitable material for precast as well as cast-in-situ segmental linings for tunnels and mine shafts. This paper attempts to consolidate all the innovations and improvements made over the past few years in the field of macro synthetic fiber reinforced concrete technology and its application in segmental tunnel linings by coursing through available research and literature related to the subject under consideration. The comprehensive review will be useful for future designers and tunnel engineers to achieve better stability, strength and performance during construction of segmental lining for tunnels.
