| Summary: | 碩士 === 東南技術學院 === 防災科技研究所 === 96 === This study following the Marshall mix design method is applied to cold-mix asphalt for determination of the optimum emulsion asphalt contents. The Ethylene-Vinyl Acetate (EVA) or Portland cement I (Type I) as an additive was added into mixtures for evaluation. Compared with the engineering properties of the different types of cold-mix asphalt from Taiwan and Korea, the Marshall stability values and flow, indirect tensile stress, and wheel load tracking test for cement-asphalt mortar, SMA with wood, SMA with mine fiber were undergoing.
The test results show that the mixtures are relationship with the temperature and their chemical properties. The stability values are following as the order: additive using Type I cement > cold-mix asphalt from Korea > cold-mix asphalt from Taiwan > additive using EVA; the flow values are: additive using EVA > cold-mix asphalt from Taiwan > cold-mix asphalt from Korea > additive using Type I cement; the indirect tensile stresses of cold-mix asphalt from Taiwan and Korea can not be obtained; and the rut depths are: cold-mix asphalt from Taiwan > cold-mix asphalt from Korea > additive using EVA at temperature of 40℃, however, CA mortar > SMA with wood fiber > SMA with mine fiber > additive using Type I cement at temperature of 60℃.
Finally, for energy conservation and environmental protection reason using cold in-place recycling (CIR) asphalt concrete in field test at Taipei city was verified to see the possibility of the replaced hot mix asphalt (HMA) for maintenance. After one month evaluation, the rutting resistance is better than the HMA.
