Starpeco supplies a comprehensive range of bitumen grades for road construction and industrial applications across Tanzania — penetration grades, performance grades, and cutback bitumen.
Bitumen is a highly viscous petroleum-derived binder obtained from the fractional distillation and refining of crude oil. It binds aggregates together to create asphalt surfaces capable of withstanding heavy traffic, extreme temperatures, and environmental stress.
Selecting the right grade is critical — it directly affects durability, flexibility, and lifespan of the pavement. Starpeco supplies all major grades and product types, serving Tanzania's road contractors, government programmes, and airport works.
From BRT corridors to airport runways — Starpeco bitumen has been specified on some of Tanzania's most demanding infrastructure projects.
Classified by hardness — a needle penetration test determines the grade. Higher values mean softer bitumen; lower values mean harder. Widely used in road construction and pavement applications for binding, waterproofing, and durability.
PG bitumen is commonly specified by international contractors and government programmes where durability and long-term reliability are non-negotiable — including BRT infrastructure, airport aprons, and national highway upgrades.
PG Bitumen is classified by its performance under specific pavement temperatures and traffic conditions — evaluated for rutting resistance at high temperatures, fatigue cracking at intermediate temperatures, and thermal cracking at low temperatures.
Produced by blending penetration-grade bitumen with a volatile petroleum solvent to temporarily reduce viscosity — making it more fluid and workable at lower temperatures. After application, the solvent evaporates, leaving behind the original bitumen binder for adhesion, waterproofing, and strength.
Used for prime coats, surface dressing, and patching works across Tanzania and East Africa.
