In proportion to increasing porous pavements, demand and application of high viscous polymer modified asphalt grows, and quality management and evaluation becomes more important in the ordering system based on performance-related specifications. However, dispersing morphology and qualitative characteristics in manufacture and storage of this compound material which is thermo-plastic elastomer melted with heat in asphalt, is yet to be clarified, while more reliable guarantee on its quality is required. So far we have been studying evaluation methods of the characteristics of this material during manufacturing process, using indoor pilot equipment made similar to the real factory equipment Hereby, we examined material separation during storage after shipment from manufacturer's tank to the users such as asphalt mixture plants, which constitutes a primary issue in considering quality guarantee. |
