THE LOW-TEMPERATURE BEHAVIOUR OF ASPHALT WITH SYNTHETIC SILICIC ACID
KAELTEVERHALTEN VON ASPHALT MIT SYNTHETISCHER KIESELSAEURE
This report deals with the evaluation of the low temperature behaviour of asphalt mixtures containing synthetic silicic acid, using the relaxation test method. In the range of temperatures employed, it was shown that the binder stiffening effect of the silicic acid diminishes as the temperature falls, while the relaxation capacity approaches that of the binder used. It may be concluded from the tests that there is no risk of an adverse increase in the relaxation time as a result of adding silicic acid, and that any such increase decreases with falling temperature.
