| 摘 要： | 根据隧道内部环境和车辆运行特性,提出了采用多孔混凝土来克服隧道路面抗滑耐久性不足的问题.针对多孔混凝土的强度性能和施工特性,通过强度试验提出了多孔混凝土的合理配比和合适的施工工艺.结果表明,采用湿-湿法施工可以显著提高多孔混凝土路面上、下层间界面的粘结强度.

| Abstract: | The investigation and analysis indicate that the environment and characteristic of vehicle operation in road tunnel require better durability of surface skid-resistance.Open graded cement concrete(OGCC) could be used to meet the need of the durability of skid-resistance.Through the laboratory test,the reasonable compostion of OGCC to achieve the strength requirements as road pavement is established and a reasonable construction technique to ensure the bonding strength between the OGCC layer and the underlayer is put forward.The results show that higher strength could be achieved by using W-W method. |
