dc.description.abstract | Compared with other materials, cold-mixed recycled asphalt concrete pavement has more obvious development trend of aging strength that is necessary to discuss the relationship between the strength and curing time, which is helpful for the use of the material in pavement. In terms of domestic and foreign applications, cement can increase the anti-stripping ability and enhance the solidification, which make the curing time have discrepancy. The study uses Light Weight Deflectometer and Clegg Impact Soil Tester to determine the ELWD and Clegg Impact Value (CIV), in the light of studying the age strength of development of the cold mix recycling asphalt concrete to confirm the material properties. The strength of cold mix recycling asphalt concrete has a rapid development in the initial curing time, and gradually leveling off in the late period. However, the aggregate gradation has no obvious development. According to the strength development curve module, the regeneration between the ELWD and aging time is y=4.24ln(x)+24.13, and R2 is 0.9; To ensure the strength of the material, this study recommends the use of this material for the new construction project, the curing time is 24 hours, and the maintenance project is 4 hours. The test road in New Taipei City can meet the recommended strength requirements of the strength development curve of this study within 1 hour and 15 minutes of curing time. Based on the above points, the application of cold-mixed recycled foamed asphalt in pavement engineering does have its advantages and competitiveness, and it is well worth it in Further research and application. | en_US |
