Abstract
The invention relates to asphalt emulsions comprising an asphalt component selected from the group consisting of a solvent extracted asphalt, an oxidized asphalt, and combinations thereof. The invention also relates to products made therefrom, including fibrous mats comprising a fiber component, such as glass fibers, and a binder component comprising an asphalt emulsion. The invention further relates to wet-laid processes for manufacturing fibrous mats and that employ the use of an amphoteric surfactant, which is applied to a wet fiber web prepared from a dispersion of fiber components, such as glass fibers.
