In this study, presents methods on the reuse of leftover sulphur and examines the mechanical properties of pavement material containing sulfur polymer emulsion (SPE) for use in semi-rigid pavements. As the result of study, the optimum replacement level of acrylate with SPE was found to be 25% in consideration of various properties

This paper presents the effect of tensile strength of PP fiber on the fiber bridging behavior and density, compression, and tension test results of high strength PP fiber based fiber reinforced composite that has high strength as well as high ductility.

The results of the durability analysis of chloride attack and analysis of hydration heat, it was found that it was convenient to obtain the service life and minimum crack index of TBC from a wide range of water-binder ratio. However, it was analyzed that the crack index was difficult to obtain.

Semi-Rigid Pavement is one of excellent paving methods adopting merits of Ascon and concrete paving. But, it has placed just only normal road pavement. In this case, we have constructed Semi-rigid pavement method at Deck pavement on service bridge and we have estimated Semi-rigid pavement as a new paving method replacing Ascon and concrete pavement.

The purpose of this study is to evaluate the axial compression(P) - bending moment(M) interaction of PHC pile reinforced with infilled concrete and rebar. A type of 500-80t PHC pile was used for evaluating P-M interaction. From the result, the P-M of PHC pile reinforced with infilled concrete and rebar was evaluated approximately 24% and 64% higher than that of conventional PHC pile respectively.

In this study, the hydration heat and chloride migration properties of marine concrete with respect to the water-binder ratio and binder type are investigated experimentally. According to research results, TBC(Ternary Blended Cement) applied marine concrete has a large water-binder ratio, the heat of hydration was found to be reduced and the chloride ion diffusion coefficient was small.

To secure the early strength of ternary blended cement mortar, using 3.5% anhydrite with a fineness of approximately 10,000cm2/g, was found to provide the most outstanding early strength properties.
