Abstract
Method for the evaluation of bitumen in asphaltic mixtures, characterized in that a sample of asphaltic mixture is subjected to an ultrasonic washing action, based on immersing it in a bailo with solvent or surfactant, preferably trichlorethylene, at a temperature close to that of boiling, to which an ultrasonic vibration is communicated, by means of a high-frequency generator, in order to separate the polluting layer or stain from bitumen from the aggregates, so that the washing action is the result of the combination of the effects of ultrasound and cavitation or bubble shedding caused by that, which determines the erosion of the film, its dispersion and the increase in the rate of dissolution, all due to the ability of these bubbles to enter between the film and the surface of the aggregate, in which the high frequency of the oscillations in the bubbles fatigates the material at the interface producing erosion ny rupture of the film, while the ultrasound produces concentration gradients that accelerate the diffusion and dissolution of the bitumen, effecting a filtering operation of the liquid through a very small pore filter to reduce filler losses, allowing the solvent to evaporate., after which the aggregate is weighed to know the difference with the initial weight of the asphalt mixture and establish the proportion in which said bitumen intervened in it.
