Study on Compaction Characteristics of SAMPAVE Mixture

SAMPAVE mixture has the characteristics of anti-cracking,anti-leakage and adhesive.In order to research its compaction characteristics,the grading range and volumetric parameters of the mixture are deduced by the gyratory compactor(SGC) method and the Marshall method in the paper.The SGC curves are analyzed and the conclusion is that 50 times compacting is reasonable.The control indexes of volumetric parameters of the SGC method and the Marshall method are recommended.Comparative analysis of the volumetric parameters between the SGC method and the Marshall method is carried out,and the following conclusion is drawn: asphalt content in project needs lower 0.2% of the optimum asphalt content designed by the Marshall method.
