SUMMARY DESCRIPTION

Special Polymer Gilsonite " Natural Asphalt Natural Bitumen improves the high temperature properties of asphalt and is a reinforcing agent for hot mix asphalt (HMA). This grade has superior purity and a finer particle size distribution compared to conventional Gilsonite grades. It can be directly blended into the asphalt binder. CH109P R K widens the Useful Temperature Interval (UTI) of the finished product and is a cost-effective means to either substitute or complement polymer-modified asphalt (PMAs). CH109P R K can also be added at the asphalt plant during manufacture of HMA. Gilsonite is a natural asphalt and is fully miscible in the base binder, thus the final Gilsonite-modified asphalt (GMA) is inherently phase stable. GMAs produce paving surfaces with higher stability, superior rut resistance, improved resistance to water stripping, and reduced temperature susceptibility.

Generally, asphalts are characterized by their physical properties:

Softening Point: Range of temperatures that the asphalt softens using a ring and ball technique. Sometimes thought of as
the melting point.  ASTM D-36

Penetration (at a prescribed temperature): How far a weighted needle or cone will sink into the asphalt during a set period of time. ASTM D-5

Viscosity (at a prescribed temperature): An indication of how thick or thin the liquid asphalt is at various temperatures (measured in poises, centipoises (cps), centistokes (cSt), or SSU). ASTM D-2170, D-88

Flash Point: Temperature that the heated asphalt will flash (ignite briefly). ASTM D-92

The softening point and penetration are usually the most commonly used measurements for classifying an asphalt's properties. Generally, when comparing asphalts, as the softening point increases, the viscosity also increases, the penetration drops and the flash point rises.

PACKAGING

SPG-350 is available in 50 lb. and 25 kilo net multi-ply paper bags, which may be palletized and stretch wrapped. It is also available in meltable plastic bags, bulk loaded trucks, and in a variety of bulk bag sizes.

HEALTH & SAFETY

Gilsonite is a naturally occurring hydrocarbon. There is no known history of dermatitis, lung disease or other health problems associated with handling of Gilsonite as supplied. Dusts are subject to combustion. Normal precautions used with flammable materials apply.
