Identification of Rejuvenators on Porous-Asphalt Concrete Using Optical Microscopy and Nanoindentation Technology
AbstractApplication of rejuvenation products on porous asphalt pavements as a preventive maintenance technology has been investigated recently by the Dutch Ministry of Transportation. Traditionally, the main contribution of rejuvenators to porous asphalt pavements is considered as restoring its flexibility. Whether this really is the case is investigated in the research reported in this paper. For this purpose, identification of rejuvenators is done using optical microscopy and nanoindentation technology. Visual inspection from optical microscopy shows that all applied rejuvenation products, except for bitumen emulsion BE-1, provide an additional bituminous binder film to the mortar and also fill microcracks. The decrease of indentation modulus of the mortar shows that BE-1 and BE-2 can penetrate into the mortar and improve its flexibility.
