BITUMEN
PROCESSING
The DRC requires approximately 100,000 MT of bitumen annually for road construction and maintenance. STE LRI GROUP SARL targets 30,000 MT per year — producing penetration bitumen, cutback grades (MC-30, MC-70, MC-3000) and cationic emulsions (K1-60, K1-70) for every application.

Bitumen 60/70
Penetration Grade · ASTM D946 / EN 12591
Primary road construction bitumen for tropical climates. Ideal for hot-mix asphalt surfacing on DRC national highways and urban roads.
Bitumen 80/100
Penetration Grade · ASTM D946 / EN 12591
Softer penetration grade preferred for high-temperature climates and secondary roads where more flexibility is required during placement.
MC-30
Medium Curing — Slow · ASTM D2027
The most fluid MC cutback grade. Blended with lighter petroleum distillate solvents for ease of application at ambient temperature — ideal for prime coats and dust suppression on unpaved roads.
MC-70
Medium Curing — Medium · ASTM D2027
Mid-range MC cutback grade offering a balance between fluidity and early strength development. Widely used for prime coats, tack coats, and maintenance patching of DRC road networks.
MC-3000
Medium Curing — High Viscosity · ASTM D2027
High-viscosity MC grade for heavy-duty road base stabilisation, chip seal programmes, and applications where a stiffer mix is required before curing. Designed for large DRC infrastructure contracts.
K1-60
Cationic Slow-Set Emulsion · ASTM D2397 / EN 13808
Cationic slow-set bitumen emulsion with 60% bitumen content. Designed for cold-applied road surfacing, recycled asphalt mixes, and slurry seal programmes — no heating required at site.
K1-70
Cationic Slow-Set Emulsion · ASTM D2397 / EN 13808
Higher bitumen content (70%) cationic slow-set emulsion for superior film thickness and better performance in high-traffic applications. Preferred for urban cold-mix overlays and surface dressing in the DRC.
