BITUMEN
BITUMEN
Bituminous materials, a by-product of the oil distillation process, look set to remain as a constituent material of road paving for some considerable time to
come, being used to withstand the flexural and compressive stresses caused by traffic. Due to the ever increasing intensity of today’s traffic conditions there
is a demand for higher levels of performance from asphalt.
This section includes a wide range of testing equipment to fulfill all Standard requirements.
AUTOMATIC SOFTENING POINT: Ring and Ball Tester
The Automatic Ring and Ball Testeris a high-precision, microprocessor-controlled instrument used to determine the softening point of bituminous materials. It provides a completely automated testing environment, utilizing infrared sensors to detect the exact moment of specimen failure, ensuring consistent results that are free from human observation error.

PIVOT: Fully Automatic Penetrometer
The PIVOT is a high-tech, fully automated penetrometer designed for the precise determination of bituminous material consistency. Unlike manual or semi-automatic models, the PIVOT utilizes advanced closed-loop electronic control and a displacement transducer to eliminate operator bias, ensuring unmatched repeatability in penetration tests.
Key Performance Features

- Standard & Verified Needles: Available with official calibration certificates for high-stakes quality control.
Pressure Aging Vessel (PAV)
The Pressure Aging Vessel (PAV) is a specialized instrument designed to simulate the long-term oxidative aging of asphalt binders over a 5 to 10-year service life. This essential process follows the initial short-term aging of the RTFOT and is a core requirement for Superpave performance-based testing.
Key Performance Features
- Intelligent Touch-Screen Control: Equipped with a 6″ color reclinable touch-screen, allowing operators to monitor vessel pressure and temperature in real-time via live graphs and data readouts.
- Rapid & Uniform Heating: Features highly efficient encased band heaters and PID temperature control that reaches the set point in less than one hour, exceeding international standard requirements.
- Programmable Pre-Heating: Includes a safety-limited pre-heating function (up to 60°C) to ensure the vessel is ready for testing immediately upon sample loading while protecting the operator.
- Safety-Centric Design: * Electronic Top Cover Lock: Prevents the lid from being opened while the vessel is pressurized or during the active test cycle.
- Forced Ventilation Cooling: A built-in system that quickly cools the sample rack after the test to prevent accidental burns.
- Over-Pressure & Over-Temp Protection: Integrated mechanical relief valves and software-driven cut-offs ensure total lab safety.
Compliance & Standards
- ASTM D6521: Standard practice for accelerated aging of asphalt binder using pressurized air.
- AASHTO R28: The American Association standard for pressurized aging of asphalt binder.

System Integration
To meet mandatory laboratory requirements, the PAV is typically paired with the Vacuum Degassing Oven (VDO). This removes air bubbles from the aged binder, making the sample ready for further testing in a Bending Beam Rheometer (BBR) or Dynamic Shear Rheometer (DSR).
Rolling Thin Film Ovens (RTFOT)
The RTFOT (Rolling Thin Film Oven Test) is a critical laboratory instrument used to simulate the short-term aging of asphalt binders. This process mimics the hardening that occurs during the high-heat stages of mixing, hauling, and paving. By exposing a moving film of bitumen to heat and air, it prepares samples for further performance testing via DSR, PAV, or BBR.
Key Performance Features
- Touch-Screen Intelligence: A high-resolution 7″ color touch-screen (on advanced models) provides real-time monitoring of temperature, carousel speed, and airflow.
- Rapid Heat Recovery: Engineered to reach the target temperature of 163°C within minutes of sample loading, exceeding the strict recovery time requirements of international standards.

- Softening Point Testers: The softening point test is done to find the temperature range below which the bitumen is semi-solid and above which it tends to act more or less like a liquid. This information enables the engineers to determine the Bitumen Testing Equipment response to high temperature which is a critical factor in UAE climate.
- Ductility Testing Machines: These machines measure the extent to which the material known as bitumen can be pulled without cracking. In terms of traffic loads ductility is an essential characteristic of a material as this will determine the flexibility of the bitumen at any given time.
