EXAMINATION OF APPLICABILITY BY PERFORMANCE VERIFICATION OF MIXTURE FOR PERFORMANCE REGULATION OF HIGHLY DURABLE GUSS ASPHALT MIXTURE

For the base layer of the steel deck pavement of the Hanshin Expressway, guss asphalt mixture that has high deflection followability, can be constructed by pouring, and can be easily filled into uneven parts on the steel deck has been conventionally used. In recent years, pavement road companies have been making efforts toward the practical application of pavement with high durability and low odor compared to conventional guss asphalt pavement. On the other hand, the standards for applying the highly durable guss asphalt mixture to the base layer mixture on the steel deck have not been established on the Hanshin Expressway. In this paper, various tests were conducted to evaluate the performance required for the base layer of the steel deck pavement for the purpose of defining the performance of the highly durable guss asphalt mixture. As a result, it was confirmed that most of the highly durable guss asphalt mixture used in this study has excellent flow resistance and crack resistance compared to the conventional guss asphalt mixture.
