The first visual sign of this is a change in color from black to brown to gray. As asphalt is a byproduct of petroleum distillation processes, it is easily dissolved by the numerous other goods that are also derived from petroleum. This is simply because these person items come from the same supply, and therefore have a all-natural affinity for one another and will try to rejoin when place with each other again. Consequently, oil and gasoline both function to easily dissolve asphalt, which contains many extremely comparable chemical substances.
