All bridges are inevitably undergoing deterioration over time. Therefore, it is necessary to predict the maintenance control and to properly manage the maintenance control cost by deriving the appropriate repair and reinforcement timing. The deterioration of bridges appears to vary according to the years of use of bridges and the exposed environment. In this study, the correlation between the deterioration factor of the winter season and the damage rate of the bridge deck was derived from 1117 total bridge data collected through the GPR(Ground Penetration Radar) system.

Characteristics of bond strength between AR-glass textile and fine concrete was performed through pull-out test with various transverse reinforced methods as number of lateral reinforced textile and transverse development length. In the both case of change in reinforcing method, bond strength was increased sharply in the first case.

Reinforced concrete is used as a main construction because it is excellent durability and strength. However, the problem of durability decrease due to enlargement, high-rise of structures and the cracking due to external force nowadays. Therefore, there is studying on the Textile Reinforced Concrete(TRC), which reinforcing bar changing into Textile. Also, studying on adhesion performance between concrete and Textile. Preceding studies have examined the adhesion performance of single fibers with no specific variable. It can not reflect about grid type and embedding length. Accordingly, on this study examines the change of bond strength according to bond length. As a result, the bond strength increased as the embedding length of the Textile increased, but there was not influence that the bond strength according to the lateral length.

Characteristics of bond strength between AR-glass textile and fine concrete was performed through pull-out test with various transverse reinforced methods as number of lateral reinforced textile and transverse development length. In the both case of change in reinforcing method, bond strength was increased sharply in the first case.

Change in the adhesion strength between AR-glass textile and concrete was performed through pull-out test with longitudinal (load direction) and transverse development length. In case of longitudinal development length, adhesion performance was not shown. But in case of transverse, adhesion performance was increased according to the increasing transverse textile length.
