Paveflex 140 is a special developed polymeric compound containing different functional modifiers and additives and is recommended for modifying bitumen 60/70 to meet the Superpave binder specification for asphalt concrete roads specified by relevant road authorities.
Paveflex 140 blended with bitumen 60/70 penetration grade can easily achieve performance grade PG 76—10 and PG 82-16 which is required for heavy traffic roads. Paveflex 140 exhibits excellent compatibility and storage stability with bitumen. The Paveflex 140 modified PG grade asphalt exhibits improved resistance to rutting, shoving, stripping, water stripping, load bearing, cracking and have excellent adhesion
EXXONMOBIL CHEMICAL POLYBILT™ 101 AND 106
The addition of ExxonMobil Chemical Polybilt modifiers to bitumen (asphalt) results in improved performance, greater durability and easier processing.
Under increasing traffic and diverse weather conditions, asphalt road surfaces progressively lose their mechanical performance.
Polybilt modifiers work to:
• Widen the working temperature range of road surfaces
• Improve road mechanical properties, including rutting resistance
• Enhance bitumen performance and handle increasing traffic loads
• Reduce pavement thickness
• Increase pavement durability
At high temperatures, asphalt is subject to softening that leads to rutting and bleeding. Extreme low temperatures can result in cracking and loose chipping. Polybilt modifiers expand the range of surface consistency to minimize deterioration and breakdowns.
Mixing Polybilt modifiers is easy and efficient, as it can be blended with bitumen in a wide variety of equipment, including standard low shear mixers. Polybilt can also be mixed in about half the time of other polymers, and does not require time for the polymer to “swell” into the bitumen to reach optimal properties.
