Abstract The effect of aging on the mechanical properties silicone rubber (SR) was investigated by means ultrasonic, dynamic analysis, and FTIR techniques. Both longitudinal shear (Ultrasonic wave velocities) were measured at room temperature frequencies 2 MHz. Density, molar volume, ultrasonic velocities, tensile strength, properties, FT–IR showed improvement network with time from 0 to 70 day...

In general, the physical and rheological properties of asphalt binder are directly affecting resistance mix to permanent deformation (rutting), water damage, thermal cracking. The degradation in these leads severe distresses that appear pavement and, consequently, make repair maintenance very expensive. Since modified-asphalt cement may help minimize such aforementioned distresses, this researc...
