The Influence of Ageing on the Fatigue and Healing Properties of Bituminous Mortars

For asphalt pavement design in Belgium, healing is taken into account as a standard shift factor, representing the effect of rest periods between loadings of traffic. Because nowadays Reclaimed Asphalt Aggregate (RA) is widely used in hot mixtures, a new validation of the healing factor is needed. Given the lack of test results and a standard healing test for mixtures, a new test method for the evaluation of healing on mortar samples was evaluated using Dynamic Shear Rheology (DSR). This paper reports the test settings and results; specific attention is given to DSR stress and strain modes in software and output.
