Scheme AScheme BScheme CScheme D

Maintenance mode8 cm thick ordinary concrete8 cm thick steel fiber concrete8 cm thick quick cement concrete6 cm thick steel fiber concrete and MRK + 2 cm thick ultrathin wear layer; steel fiber-reinforced concrete (85%); MRK (15%)

Maintenance costs6.14 million yuan6.83 million yuan17.54 million yuan10.28 million yuan

Maintenance cycle150 d150 d140 d160 d

Traffic loss31.61 million yuan31.61 million yuan29.50 million yuan33.71 million yuan

Maintenance characteristicsMature process; weak tensile and shear strengthGood crack resistance; good integrity of the bridge deck, high toughness, and tensile strength; steel fibers rust easily [27]Time is short; the price is more expensive; new materials; new technology; performance and durability are not widely provenThe landscape effect is good; good durability; more material types; complicated construction technology [28]
