| Abstract: | According to reasonable preparation technology,the 90# and 70# base asphalt were modified with different types of untreated plastic and treated plastic by tracking.The experimental study on four types of waste plastic-modified asphalt was conducted by optimization segregation test.Finally,the paper made research on mechanism by means of thermal analysis.The result showed that the storage stability of treated plastic-modified asphalt by tracking was superior to untreated plastic-modified asphalt;the evaluation indexes of four types treated plastic-modified asphalt in 8h and 48h segregation test all characterize good storage stability.The findings of the research provided evidences for the popularization and application of domestic waste plastic-modified asphalt. |
