Pavement Performance of Cold Recycling Sulphur Asphalt Mixture with Emulsified Asphalt
In order to investigate the pavement performance of cold recycling sulphur asphalt mixture with emulsified asphalt, freezing and thawing test, rutting test,shear test,bending test, fatigue test and compression test were carried out.Results showed emulsified asphalt cold recycling sulfur asphalt mixture possessed an excellent high temperature stability, as RAP content increased,the splitting and compressive strength,shear strength,compressive modulus of resilience,low temperature crack resistance,fatigue performance all gradually reduced.When sulphur content of asphalt mixture RAP is less than 70%, cold recycling sulfur asphalt mixture can meet the demand of road base; when the sulphur content of asphalt mixture RAP is less than 50%, the mixture can meet the demand of the bottom layer of asphalt pavement.
