| Abstract: | Aiming at solving the problem of cracking in the continuous rigid-structured bridge,we have the mixture ratio-determining process for the polypropylene-fibre-concrete of the box girders of the No.2 Mega Bridge at Bayang of the Yun-Wan Expressway introduced in the paper.Practice proves that polypropylene-fibre-concrete is fairly good in crack resisitance and durability. |

| Keywords: | polypropylene-fibre high strength concrete mixture ratio crack resistance |
