Experimental Study on Multi-index Content Optimization of Palwisite Modified Asphalt
Palychite is a kind of low cost polymer composite modified material,which has the potential to improve the high stability and anti-aging properties of asphalt.In order to investigate the influence of palywisite on the physical properties and anti-aging properties of asphalt,the optimum content of palywisite in asphalt was determined.Modified asphalt with different content of palwisite was prepared,and the changes of penetration,softening point and elongation of asphalt before and after aging were tested.The optimization model of palwisite modified asphalt content was established by AHP and fuzzy mathematics.The superiority degree of modified asphalt under different content ofpalwisite was cal-culated by replacing the measured index of asphalt into the model.
