Research on Aging Properties of Tourmaline Modified Asphalt
Aging properties of tourmaline modified asphalt prepared by melt blending were studied. The change laws of aging properties of asphalt caused by different types and contents of tourmaline were studied systematically by rotated thin film oven tests (RTFOT), in which the indices of aged residues such as softening point, penetration and ductility were tested. The results showed that the anti-aging performance of asphalt was improved effectually with addition of tourmaline, the ratio of residual penetration and ductility increased, and the softening point increment of aged asphalt decreased. The improvement of anti-aging performance of asphalt reduced with the increasing mixing amount of tourmaline. Tourmaline anion powder (5000ions) was recommended to improve the anti-aging performance of asphalt.
