RoadChem™ 108® and 108 P® Polymer Modifier for Asphalt
RoadChem™108® is a radial SBS block copolymer polymer designed to improve the rheological properties of asphalt. It has a wide range of compatibility with different asphalts made from different crudes and using different processing methods.
- Radial Block copolymer.
- Contains <10% diblock.
- Medium styrene, high modulus copolymer.
- Outstanding strength.
TYPICAL PHYSICAL PROPERTIES:
Form: Free flowing porous pellet or powder(108P).
Styrene %: 30%
Diblock content: 10-12%
Density: 0.94 (ASTM D-792)
Tensile strength: 4000psi (ASTM D412)
Hardness Shore A: 71 ( ASTM D-2240)
300% modulus: 650psi( ASTM D-412)
Elongation at Break %: 725 ( ASTM D-412)
Storage Life: Indefinite in sealed 50 lb bags.
Blending: Roadchem™ 108 may be blended using conventional equipment , a high shear mill is required similar to Emultech® PMB blending plants.
TYPICAL FORMULATION: All formulations should be tested in the laboratory before use.
Asphalt should be checked for compatibility by making mixtures in the laboratory. VSS can assist with this process.
A typical formulation for a binder for high deformation resistance will contain 3-5% by weight Roadchem 108® blended with 80/100 pen or other asphalt.( e.g 30/40, 50/70, 180/220 or ANY other Grade)
The mix should be designed in accordance with good practice.
Roadchem™ 108® is non hazardous. Refer to the MSDS for further information.
