Study of the technical performance on the domestic TPS high viscosity modified asphalt

摘要

This paper investigates the technical performance of the high viscosity modified asphalt added the domestic TBS high viscosity modifier under different content. Test results indicate that all indexes of the high viscosity asphalt which added 15% domestic TPS are best, through the tests such as penetration test, softening point test, toughness test, tenacity test, 60°C dynamic viscosity test, 135°C rotational viscosity, elastic recovery test. The author also takes a series of tests such as binder drainage test, Cantanbro stripping test, wheel tracking test, the flexural bending beam test and moisture susceptibility test on the porous asphalt mixture which added 15% domestic TPS, test results indicate that the modified asphalt has perfect characters such as high temperature stability, low temperature crack resistance, moisture damage, anti-caking.
