Asphalt Emulsion Emulsified asphalt, as used by TxDOT, consists of asphalt droplets suspended in water. This dispersion under normal circumstances would not take place, since everyone knows that oil and water don't mix, but if an emulsifying agent is added to the water the asphalt will remain dispersed.
اقرأ أكثرEmulsified asphalt is simply a suspension of small asphalt cement globules in water, which is assisted by an emulsifying agent (such as soap). The emulsifying agent assists by imparting an electrical charge to the surface of the asphalt cement globules so that they do not coalesce (Roberts et al., 1996 [1]).Emulsions are used because they effectively reduce asphalt viscosity for lower ...
