Feasibility of cold recycled sulphuric asphalt mixture with emulsified asphalt

In order to investigate the pavement performance of cold recycled sulphuric asphalt mixture with emulsified asphalt,sulphuric asphalt mixture RAP and asphalt mixture RAP are used for mixture proportion design,freezing and thawing split tensile strength test,rutting test, shear test,low temperature bending test and compression test are used to find the water stability,high-temperature stability,anti-shearing performance,low-temperature anti-cracking performance,compressive modulus of resilience,and Comparative studies on the performance are carried out between sulphuric asphalt mixture RAP and asphalt mixture RAP,and the mixture properties under different RAP content.The test results show that both cold recycled sulphuric asphalt mixture and cold recycled asphalt mixture with emulsified asphalt have the similar properties,and increased RAP using will result in decreased performance of the mixture.
