Research on Aging Mechanism and Recycling Mechanism Based on Asphalt Four Components Analysis

Abstract:

Asphalt aging mechanism and recycling mechanism are studied in the paper, based on four components tests for aging asphalt and recycling asphalt, by comparing and analyzing the D-value between testing data and theory calculated data. Results show that asphalt four components changes regularly for aging asphalt, which some saturates and aromatics are changed into some asphaltenes and colloid. And the recycling mechanism is not regular for the same asphalt, which the mix result of asphalt four components depends on many factors, such as degree of aging, quantity of old asphalt, components and quantity of recycling agent. The study results can provide important theoretical basis for sustainable use and development of regeneration asphalt.
