Decision Method of Bridge Deck Pavement Maintenance Based on the Decision Maker’s Objective
Table 2
Bridge deck pavement maintenance scheme.
| | Scheme A | Scheme B | Scheme C | Scheme D |
| Maintenance mode | 8 cm thick ordinary concrete | 8 cm thick steel fiber concrete | 8 cm thick quick cement concrete | 6 cm thick steel fiber concrete and MRK + 2 cm thick ultrathin wear layer; steel fiber-reinforced concrete (85%); MRK (15%) |
| Maintenance costs | 6.14 million yuan | 6.83 million yuan | 17.54 million yuan | 10.28 million yuan |
| Maintenance cycle | 150 d | 150 d | 140 d | 160 d |
| Traffic loss | 31.61 million yuan | 31.61 million yuan | 29.50 million yuan | 33.71 million yuan |
| Maintenance characteristics | Mature process; weak tensile and shear strength | Good 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 proven | The landscape effect is good; good durability; more material types; complicated construction technology [28] |
