Quality Control testing: Run routine physical tests on raw materials and finished bituminous products to ensure compliance with SANS specifications and client requirements.u

• Modified bitumen: Tests polymer modified bitumen smples (PMB) for Penetration, softening point, Elastic recovery, viscosity etc.t
• Emulsion Analysis: Test anionic and cationic emulsions for critical properties including, viscosity, water content (binder content), residue on sieving, etc.t
• Monitored formulation, binder content, viscosity, and distillation properties of cutback bitumen to maintain product integrity.
• Calibrated and verified sensitive laboratory apparatus including penetrometers, Brookfield viscometer, auto softening point tester, sybolt, ovens, and distillation apparatus to ensure accurate testing.
• pH verification and testing: Calibrating pH meter and conducting water pH and Emulsion pH analysis.
• Captured and recorded accurate test results on Excel; compiled monthly reports and issued Certificates of Analysis to ensure compliance with quality assurance standards.
• PG Testing: Advanced asphalt Penetration Grade

Operate performance graded equipment (PG) binder equipment, including Dynamic Shear Rheometer (DSR), Bending Beam Rheometer (BBR), Pressure Aging Vessels (PAV) and Vacuum Degassing Oven (VDO).
