Dalton SS-1H asphalt binder is an anionic emulsion designed for use as a tack coat for patching, paving, overlays and coating blacktop. SS-1H promotes adhesion to blacktop (bituminous concrete). It can be applied via spray, brush or squeegee and dilution is not necessary. Most all sprayers will work.
3 5. SIGNIFICANCE AND USE 5.1 Pullout tensile strength values measured over a range of environmental conditions and curing times provide information related to the bond strength at the interface between a substrate and hot-applied or emulsified asphalt binder.
2.3 OverKote® Oil Spot Seal as manufactured by Diversified Asphalt Products INc. – a quick drying latex emulsion with suitable additives to coat and promote adhesion of the sealer to oil, grease and gasoline stained pavement. 2.4 Emulsified Asphalt Binder – shall conform to State of California specifications for SS 1h Asphalt Emulsion.
practical method for checking the rate of application of asphalt emulsion in both the longitudinal and transverse directions is provided by ASTM D2995. For satisfactory application of asphalt binder uniform pr essure must be maintained in the spray bar. The optimum pressure discharges asphalt binder at a constant rate
Asphalt Binders. The asphalt paving industry today faces many challenges including an aging infrastructure, reduced agency funding, rising costs, and the need for improved environmental stewardship and sustainability.
The Asphalt Institute?s manual, “MS-26 -The Asphalt Binder Handbook,” defines emulsification as “a process through the use of certain mechanical and chemical processes, that allows two or more materials to combine that will not mix under normal conditions.” Emulsions are very common materials; ice cream is an example.
This work consists of constructing a cold laid polymer modified emulsified asphalt pavement course to fill ruts or provide an intermediate or surface course for existing pavements. The paving mixture is composed of a polymer modified emulsified asphalt binder, crushed aggregate, mineral filler, water, and other additives.
Free online knowledge for the paving industry Asphalt is a dark brown to black, highly viscous, hydrocarbon produced from petroleum distillation residue. This distillation can occur naturally, resulting in asphalt lakes, or occur in a petroleum refinery using crude oil..

By using the infrared spectrum and the principles of Beer’s Law, the polymer content of the asphalt material can be determined. This standard involves hazardous materials, operations, or equipment. This standard does not purport to address all of the safety concerns associated with its use.
Sometimes emulsified asphalt tack coats are diluted with water to increase the total volume of liquid while maintaining the same volume of asphalt binder within the emulsion. This can help achieve a more uniform application without applying excessive amounts of asphalt binder.
viscosity of an emulsified asphalt is adjusted by the method used in preparing the emul sion, by the type of emulsifier used, and by the quantity of water added. A wide vari ety of grades of emulsified asphalts are available to meet various applications. When an emulsified asphalt is used in a bituminous mix as the binder, the need for heating

Foamed asphalt is formed by combining hot asphalt binder with small amounts of cold water. When the cold water comes in contact with the hot asphalt binder it turns to steam, which becomes trapped in tiny asphalt binder bubbles (World Highways, 2001 ).).
Mar 24, 2018 · Because coal tar is an extremely easy and forgiving product to use. Since coal tar does not have as high of a solid content as asphalt emulsion, coal tar does not clog tanks and spray systems nearly as much as asphalt emulsion does. The high solid content in asphalt emulsion causes the sealer to set-up fast if not cared for in these systems.
“The ‘stickiness’ is a property of the asphalt, not the emulsion itself, and consider that the equipment is designed to apply asphalt binder,” Ishee told AsphaltPro. “Typically, the specification related to application will be included in the project plans, and the contractor will follow those requirements on behalf of the agency or ...
