Thus, when the temperature and of 52 created the the rutting aspect is positively correlated with frequency was 46 C, the asphalt complex modulus very first became larger and after that decreased as the negatively correlated with temperature. Beneath precisely the same test situations, the rutting element frequency increased. Asphalt is MCC950 Autophagy actually a viscoelastic substance whose Compound 48/80 Biological Activity deformation is divided of rubber-powder-modified asphalt isdeformation. Elastic deformation may be restored, abilinto elastic deformation and permanent larger. Because the rutting coefficient increases, the ity to resist deformation is, for that reason,restored. When the frequency increases, the action stabut permanent deformation cannot be enhanced, displaying particularly high-temperature bility.becomes shorter, plus the deformation decreases, generating the complicated mode bigger. time Consequently, when the temperature is in the array of 52 to 70 C, the asphalt complicated 4.two.2. Evaluation of dynamic Viscoelastic Characteristics the frequency is continuous, the modulus is positively correlated with frequency. When omplex modulus is negatively related to temperature, as well as the lower variety is the biggest Dynamic Modulus (46 to 52 C). The results show that the complicated modulus of the rubber-powder-modified This test prioritized the effects of the test temperature and test frequency on the dyasphalt was higher than that on the SBS-modified asphalt, indicating that the incorporation namic modulus. 3 sets of parallel tests were carried out on the rubber-powder-modiof rubber powder improved the anti-deformation capacity on the asphalt.fied asphalt mixture and SBS-modified asphalt mixture at various loading frequencies and various temperatures.

Beneath the identical test situations, the rutting issue 5 16,000 of rubber-powder-modified asphalt is larger. Because the rutting coefficient increases, the potential ten to resist deformation is, hence, enhanced, displaying extremely high-temperature stability. 20 four.2.2.
