| 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. |
