Formulation of asphalt emulsions with lignin derivatives and its behavior with mixtures of stony materials
En el presente trabajo se evaluó la utilización de los derivados de ligninas en la formulación de emulsiones asfálticas y su comportamiento como mezcla con agregados pétreos de buena calidad. En esta investigación de naturaleza descriptiva, se formuló la emulsión asfáltica con experimentos en labora...
