Performance Grade Modifier (PGM)
Asphalt Binder Upgrading Additive
PGM is an advanced asphalt binder additive engineered to significantly enhance the performance characteristics of bitumen. Designed for compatibility with a wide range of feedstocks, PGM upgrades binder quality, improves temperature susceptibility, and boosts resistance to rutting and fatigue.
Key Benefits
-
On-Site PG upgrade enables flexible polymer-modified bitumen (PMB) production, boosting revenue and project capacity
-
Energy-efficient design cuts asphalt production costs by lowering heating and storage energy costs
-
Single-grade bitumen sourcing streamlines logistics, optimizes inventory, and minimizes exposure to raw material price fluctuations
-
Reduced emissions footprint enhances sustainability while eliminating intense toxic odors
-
Built-in fiber additive removes need for separate drain-down fiber procurement and storage

Lignocell Fibers (LG Cell)
Cellulose Fiber Additive for Premium Asphalt Mixtures
LG Cell is a high-performance cellulose fiber essential for stone matrix asphalt (SMA) and open-graded mixes. It prevents asphalt binder draindown during mixing and placement, ensuring consistent mix quality and long-term performance.
Key Benefits
-
Cost-effective solution delivers premium performance at a lower price point than other cellulose fiber additives
-
Reliable draindown prevention ensures compliance with SMA and OGFC specifications while maintaining mix stability
-
Advanced mix cohesion technology enhances compaction, durability, and long-term pavement performance
-
Natural cellulose composition supports sustainability goals with a biodegradable, eco-friendly material
-
Lightweight, low-dust format improves handling, reduces waste, and streamlines storage on-site
