Gtm Design Method Is Applied Research, In The Flexible Base

Asphalt treated base is widely used in heavy road and express—highway, as it has superior pavement performance。The samples of Asphalt treated bases with Normal gradation, Beiley gradation and Superpave gradation are made with using GTM method。 The paper analyses the effect of the different test parameters on GTM experiment , and it studies the physics mechanics property, pavement performance of 11 gradations with the method of GTM。 As a result, the resisting rut performance and moisture susceptibility of asphalt admixture which is designed by GTM contain obvious exaltation than that is designed by marshall。 This confirm the method of GTM is more ccurate and reasonable than physical volume analysis method of experience。...
