Abstract: A sprayable coating composition, and method of application, for coating asphalt paving surfaces. In the coating composition, a low bulk density aggregate material of sprayable particle size is suspended in a sprayable asphalt emulsion in an amount sufficient to increase the micro-texture surface roughness of the cured coating.

Abstract: The present description relates to an asphalt coating composition, and method of application, for coating asphalt paving surfaces. In particular, the asphalt compositions comprises bitumen, a coalescent and a latex polymer, wherein the asphalt has a good drying rate, especially in cool, high humidity, or shaded conditions.

Abstract: A method of producing a cationic asphalt slurry composition which can be used as an asphalt paving sealer or as a paving or repair composition. In the method and composition, latex and other polymers are used to build viscosity and a pH buffering filler is added to prevent flocculation. Consequently, the cationic composition can be stored without irreversibly settling or separating, and without breaking for several days prior to use. In addition, non-expansive clay and a polar polymer hardening agent are used so that, when applied, the composition will set and develop strength very quickly.

Abstract: A method of making a polymer-binder composite, and the composite thus created. The method employs a high shear device that mixes together polymer with binder, and optionally with additive. The mixing is accomplished in less than one hour, less than 30 minutes or less than 3 minutes, and done at high shear rates. The shear conditions are defined by scalar shear quantity greater than 250, 1,000 or 1,500, resident time of greater than 0.05, 0.10 or 0.20 seconds, and energy utilized per unit mass of greater than 0.05, 0.10 or 0.20 kW/kg. The composite thus produced can be made with a high percentage of polymers. It can be cooled and cut into pellets that are dry and stable at normal temperatures and which can be stored or transported without heating to secondary mixing locations. The composite pellets are quickly soluble in the additional binder.

The mixing is accomplished in less than one hour, less than 30 minutes or less than 3 minutes, and done at high shear rates. The shear conditions are defined by scalar shear quantity greater than 10,000, 20,000 or 25,000, resident time of greater than 0.5, 1.0 or 5 seconds, and energy utilized per unit mass of greater than 0.5, 1.0 or 2.0 KW/KG. The composite thus produced can be made with a high percentage of polymers. It can be cooled and cut into pellets that are dry and stable at normal temperatures and which can be stored or transported without heating to secondary mixing locations. The composite pellets are quickly soluble in the additional binder.
