Abstract

Abstract: Cement and emulsified asphalt were employed to solidify RAP and stabilized soil, which were then employed to prepare full thickness cold recycling subgrade materials.We addressed the impact of emulsified asphalt adding amount change on unconfined compressive strength, indirect tensile strength and water stability of different ratios of cold recycled mixtures.We further state the function mechanism of cement and emulsified asphalt in the mixtures via microscopic test.Results show that appropriate emulsified asphalt addition can improve the performance of cold recycled mixtures, the optimum emulsified asphalt addition of 3%.Microscopic test indicates cement hydration formed space network structure interfingers with emulsified asphalt postemulsion formed asphalt network structure,not detachable.They closely combine the cold recycled mixtures to be a semirigid whole.The strength of the cold mixtures can be formed and developed.

Key words: water stability, emulsified asphalt, full thickness cold recycling, strength, cement
