Early Strength Evaluation of High-performance Emulsified Asphalt Cold Recycled Mixture

摘要

On account of the design method shortcomings of cold recycled(CR) mixture with emulsified asphalt, the material compatibility problems between emulsifier and asphalt and RAP were researched, by which the key indicators of emulsified asphalt and the emulsifying effect of different kinds of emulsifier for asphalt is concluded, and summarizes the basic principles of special emulsified asphalt selection for the high-performance CR technology. On the basis of the research at home and abroad, the early strength evaluation methods and indicators are also discussed in this paper that puts forward to three kinds of test methods: cohesive test, raving loss test, coreability test. Finally, the evaluation method was verified in practical project and reached the effect to be hoped.
