Embodiments of the present disclosure are directed to an adhesive asphalt emulsion. The adhesive asphalt emulsion can be prepared in liquid form and applied to a material, such as a film or fabric, to create a self-adhering membrane. In some embodiments, the adhesive can be water vapor permeable, and can be applied in a continuous layer to a membrane. The adhesive asphalt emulsion can be prepared, applied, and in service at low temperatures.

Modified cold applied asphalt emulsion

A method for forming a coating composition for coating a substrate comprising: blending an asphalt material; a polymer that is not a polyol; and a polyol wherein the polyol has a molecular weight of about 1000 to about 5000. Also, included are coated articles that comprise a substrate coated with a layer of the coating composition.

Method for making asphalt compositions and substrates coated therewith having improved properties

The invention includes a composition to coat a substrate comprising: an asphalt material; a polymer that is not a polyol; and a polyol. The polyol has a molecular weight of about 1000 to about 5000 and/or the polyol is present in an amount no greater than about 30% by weight of the total composition. Also included are coated articles that comprise a substrate coated with a coating layer, wherein the coating layer is formed from a composition that comprises: an asphalt material, a polymer that is not a polyol; and a polyol. Also included are methods of improving the processability of a asphalt material comprising combining together an asphalt material, a polymer that is not a polyol, and a polyol, wherein the resultant composition exhibits improved processability as compared to an asphalt composition that does not contain a polyol. In the method in some embodiments, the polyol may be present in the resultant composition in an amount of no greater than 30% by weight and/or the polyol may have a molecular weight of about 1000 to about 5000. In some embodiments, the composition of the method does not contain at least one of a plasticizer and a surface active agent.
