How to prevent and delay the emergence of reflective cracks effectively is a most important task for road researchers to the asphalt mixture overlaid on the old cement concrete pavement. Several methods preventing reflective cracks prevention have been used before, but few are satisfied. In this paper Sampave is put forward as a new method or structure which is better than the others. Base on principle of reflective cracks, a new layer named Sampave was put forward. And this paper discusses its aspaht, gradation and performance. According to the requirement reasonable gradation is suggested for practice. By means of researching on materials performance in the lab, it is obviously that Sampave has good performance at low temperature. Results of bending and creep test indicate that Sampave has good ability in resisting deformation. Meanwhile the result of fatigue test indicates that the fatigue life of Sampave is more than 210 thousand, therefore it has good performance in anti-cracking, and also the results of application in the project show its advantages in resisting reflective cracks.
