【Abstract]：Inorder to solvetheproblemofdiversifiedrecyclingof wastereclaimedasphalt pavement，the stone chips in cement stabilized macadam mixture were replaced with rap fine oil rich aggregate，and themix proportion design process of new cement stabilized macadam mixture mixed with reclaimed asphalt pavement fine oil rich aggregate was studied to verifythe feasibilityand advantages of this design method.The testresults show that thecompressive strength of reclaimed asphalt pavement fine oil rich aggregate is improvedand the compressive resilient modulus is reduced after replacing the stone chips in the ordinary cement stabilized macadam material，which is conducive to extending the service life of the pavement base.
