CRS-2P is a polymer modified, cationic water-based emulsified asphalt designed for use as a bituminous binder for chip seals. The polymer gives elasticity, reduced temperature susceptibility and durability to the finished chip seal. Polymer modified rapid setting emulsions typically have earlier chip retention than conventional emulsions.

This specification covers 11 grades of polymer-modified cationic and anionic emulsified asphalt for use in pavement construction in the manner designated. The modifier may be either a solid or a latex polymer. The modifier may be added either to the asphalt binder or emulsifier solution prior to the emulsification process.

polymer modified asphalt, polymer modified asphalt emulsion have several advantages. Emulsifying of polymer modified asphalt leads to a dried binder film that is more homogeneous and has a better polymer distribution which can improve the binder properties, particularly the ability of the binder to

Polymer can be added into asphalt emulsion in three ways: 1) pre-blending method, 2) simultaneous-blending method and 3) post-blending method. The blending method has important influence on polymer network distribution and will affect the performance of polymer modified asphalt emulsions. The absence of an agreed protocol has allowed various ...

ANIONIC SBR LATEX POLYMERS(For Anionic Polymer Modified Asphalt Emulsion Applications) (**Values are typical and not meant to be specifications.) ULTRAPAVE ® is easily co-milled into the emulsion as it is manufactured. Choose ULTRAPAVE ® 70 Series for anionic emulsions or one of our ULTRAPAVE ® cationic latexes for cationic emulsions.

Polymer Modification of Asphalt Emulsions • Emulsify polymer modified asphalt –"Pre-modified" emulsion –Polymers – SBS, SB-, EVA –Higher mod. asphalt viscosity higher asphalt + mill temp. –Exit temp. > 100oC –Heat exchanger, back press. • Polymer inside asphalt droplet

Superior Performance Asphalt. Polymer modified asphalts are made to resist regular wear and tear that cause cracking and deformation. In fact, many of our modified asphalts last up to 10 years longer. We've developed a wide range of polymer-modified specialty products to better serve the variety of needs and uses of pavement for our customers.

The emulsified asphalt shall be polymer modified. The polymer material shall be milled or blended into the asphalt or emulsifier solution prior to the emulsification process. While a three percent (3%) polymer solids, based on asphalt weight, is considered typical, other options may be considered depending on project performance expectations.

The waterborne polymer modified emulsified asphalt concrete of this present invention does not only have the advantages of conventional cold-mixed asphalt concrete, but also has good mechanical properties and stability as well as excellent pavement performance. The useful life of the road surface is greatly elongated and curing time is ...

Polymer Modified Asphalt Today's increasing loads, greater traffic volume and the need for better, longer-lasting roads demand better service from paving materials. Asphalts modified with ULTRAPAVE ® SBR Latex Polymers offer the best method of improving binders for highway, street and airport paving and maintenance projects.

Polymer Modified Emulsified Asphalt. Polymer modified emulsified asphalts shall be: either anionic (SS‐1hP) or cationic (CSS‐1hP). They shall meet the SS‐1h requirements; of Article 1009.07(a) or the CSS‐1h requirements of Article 1009.07(b) respectively, with: the following exceptions for both types: (1)

penetrations of all of the polymer-modified asphalt emulsion residues after recovery. A PG 58-28 base asphalt (115 dmm PEN) derived from the same blend of Canadian heavy crudes as used to produce the PG 52-34 base asphalt was chosen. Polymer loading levels were held constant in each formulation at 3.0 dry wt% on asphalt.

Polymer Modified MasterSeal (PMM) is a high performance mineral reinforced asphalt emulsion sealcoat blended with polymers and special surfactants for superior adhesion, flexibility, and durability. PMM is job-mixed with specifically graded aggregate and applied at a rate of 48-55% solids (unlike conventional sealers that are applied at 40% ...

want the emulsion to flow into cracks and crevices. The "2" is a high viscosity emulsion used for such applications as surface treatments. An "H" suffix indicates a stiffer/harder emulsion residue (the asphalt that remains after all the water evaporates). The designation for an additive may be a "P" for (polymer – either SBR or SBS)

8. Cost Effectiveness The cost of the polymer modified emulsion is around thirty percent higher than unmodified emulsion, however the total cost (materials, construction, traffic control, and user delay) is …

Polymer modified bitumen emulsions (PMBEs) are a special class of bituminous emulsions. There are several ways to prepare PMBEs. One possibility is to emulsify a PMB; another is to add a latex to a bitumen emulsion, either prior to the colloid mill or after. In all cases, the resulting PMBE shows improved rheological properties of the residue ...

Polymer-modified technology is used in asphalt emulsions to improve physical properties, performance, and durability. Our polymer-modified asphalt emulsions provide an increased service life and life-cycle-cost savings. They can be used in applications that are unsuited to conventional asphalt emulsions or cutbacks.

Polymer modified asphalt is produced locally at our production facility by the introduction and networking of Styrene-Butadiene-Styrene (SBS) polymers with asphalt cement to improve the binder's performance and reduce temperature susceptibility..
