THE ULTRAVIOLET RADIATION IN SHORT- AND LONG-TERM AGING OF BITUMEN

In this research the influence of ultraviolet radiation on short- and long-term aged bitumens has been studied, combining the SHRP tests (Rolling Thin Film Oven Test, Pressure Ageing Vessel) by means of a new UV standardized aging procedure. Thanks to this study it has been possible to quantify the influence of photochemical processes on rheological parameters of bitumens, and to value their percentage of incidence on the total long term aging evaluated by PAV. In particular it has been verified that the said incidence doesn't seem to be constant, but rather depending on the nature of the asphalt binder; for these reasons the effect of the UV radiation by itself, which is a real contributing term in the in situ aging process, can't be simulated by means of the standard oxidative-thermic treatments carried out in the laboratory. For the covering abstract see ITRD E107185.
