Experimental Study on Water Stability of Cold Recycled Mixture Stabilized with Emulsified Asphalt

Abstract:

Abstract: Water damage on asphalt pavement will accelerate pavement destruction, and decrease the service life of highway. Water stability of recycled mixture especially should be strengthened in design and construction of cold-recycled pavement. Taking for cold recycling technology as research object , We studied water stability and freeze-thaw stability of cold recycled mixture stabilized with emulsified asphalt, cement and emulsified asphalt through tests of Marshall stability and immersion Marshall、split test 、soaking split test and freeze-thaw split etc. The results obtained show that: Water stability of Cold recycled mixture stabilized two different additives all can satisfy requirement, and cold recycled mixture adding little cement has better stability. Cold recycled mixture stabilized emulsified asphalt can be used as highway base or sub-surface of pavement. The experiment research results provide a reliable reference for cold recycled mixture design and its applicability.
