PURPOSES: The object of this study is to select appropriate inorganic materials, and find the best mixing formula to secure fast curing time and enough initial strength, and then to evaluate the durability of the asphalt mixtures according to the degree of addition of the compound manufactured by the determined blending ratio. METHODS : The breaking time and reactivity between seven kinds of inorganic minerals, and the selected recycled aggregate and emulsified asphalt were compared to determine the best initial curing strength for the mixtures. Then, three inorganic materials were chosen as the materials that provide good breaking time and reactivity, and the best mixing formula for the three materials was determined. The chemical composition of the compound manufactured using the mixing formula was analyzed by energy dispersive x-ray system method. Finally, indirect tensile strength (ITS) test was performed (for two days) at room temperature to determine the proper amount of additives that will provide the best initial strength. RESULTS: From the results of the reactivity test, the best mixing formula (A:C:G = 60:30:10) for the three selected inorganic materials with short braking time and high reactivity was determined. The four types of cold reclaimed asphalt mixtures for ITS testing were manufactured by adding the inorganic material compounds at 0%, 3%, 5%, and 7%, and the ITS values were measured after two curing days. The ITS values at 5% and 7% were 0.308 MPa and 0.415 MPa, respectively. The results of quality control tests (Marshall stability, porosity, flow value, etc.) at 5% and 7% satisfied the specification criterion for the cold recycled asphalt mixtures. CONCLUSIONS : The selected inorganic materials (A, C, and G) and the best mixing formula (A:C:G = 60:30:10) accelerated the reaction with emulsified asphalt and shortened the curing time. Depending on the inorganic material used, the breaking time and reactivity can be directly related or unrelated. This is because of the chemical compositions of recycled aggregates, infiltrated foreign matter, and chemical reactions between the inorganic materials and other materials. Therefore, it is important to select the proper materials and the best mixing formula when evaluating the characteristics of the practically used materials such as recycled aggregates, inorganic materials, and emulsified asphalt.

Quality assessment of sweet persimmon or “Fuyu” was evaluated over room temperature distribution periods after 40-day storage at 0oC cold room. All Hunter’s values (L, a, and b) of sweet persimmon were significantly decreased after 4-day room temperature distribution while the flesh firmness was drastically decreased after 3-day room temperature distribution. Glucose and fructose contents were significantly increased by the degradation of sucrose after 3-day room temperature distribution. The highest extraction yield was obtained in the flesh of persimmon. Extraction yields of each part of “Fuyu” persimmon were 15.53% for flesh, 10.53 for seed, and 13.83 for flower bud. However, the total phenolic content of flesh was 4.8 μg/mg which was extremely lower than that of the seed (175.5 μg/ mg) and flower bud (178.2 μg/mg) of sweet persimmon. With high phenolic content, both the flower bud and seed of sweet persimmon showed excellent antioxidant activities by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis( 3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radical scavenging test. The results showed a great potential for byproducts (seed and flower bud) of long-term, cold-stored sweet persimmon “Fuyu” as a good antioxidant material for novel functional foods.
