Publication number: 20100047015Abstract: The invention is a cost-effective method and formulation for cold paving applications that can be used to convert an unpaved surface, such as a gravel or dirt roadway, into a paved surface. The method includes applying an asphalt emulsion comprising asphalt, water, one or more emulsifiers, and a polymer to an existing unpaved surface to provide a layer of asphalt emulsion. An aggregate is then deposited over the emulsion layer to form a paved surface. The asphalt emulsion is formulated so that it can be used in a wide variety of conditions and with locally available aggregate. The set rate and viscosity of the asphalt emulsion can be selected so that it is able to penetrate partially into the unpaved surface to further improve the stability and rain resistance of the roadway.Type: ApplicationFiled: August 21, 2008Publication date: February 25, 2010Applicant: BASF SEInventors: Koichi Takamura, Armin Burghart, William Kirk
