STANDART: AASHTO T48, T55, T59; EN 1428; ASTM D244
LT-AS0106 Water in Bituminous Materials Test Set
The Water in Bituminous Materials Test Set determines the water content of bitumen, bituminous materials and suitable emulsified asphalt samples by distillation. The system separates water from the sample using a water-immiscible solvent and allows the collected water volume to be read directly from the graduated receiver.
- Distillation method: Separates water from bituminous materials using a suitable water-immiscible volatile solvent.
- Precise water measurement: Condensed water collects in a graduated receiver for direct volumetric reading.
- 10 ml receiver: Supports accurate measurement of relatively small water quantities.
- Reflux condenser: Condenses water and solvent vapours during the test.
- Solvent return system: The condensed solvent returns to the boiling flask while the separated water remains in the receiver.
- Thermoregulated heating: The electric heater provides controlled heating throughout the distillation process.
- Complete glassware set: Includes the required distillation vessel, condenser and graduated receiver.
- Compact design: The complete unit measures approximately 20 × 20 × 45 cm.
- Laboratory applications: Suitable for bitumen, asphalt, petroleum product and quality control laboratories.
- Standards support: Designed for water determination procedures associated with ASTM D95, ASTM D244, EN 1428, AASHTO T55 and AASHTO T59.

What Is a Water in Bituminous Materials Test Set?
The Water in Bituminous Materials Test Set determines the amount of water present in bitumen, petroleum products and suitable bituminous materials. The system uses a controlled distillation process to separate water from the sample. Therefore, laboratories can measure water content directly by volume.
Water content is an important parameter in the quality control of petroleum and bituminous products. Excessive or inconsistent moisture may influence material storage, handling and application behaviour. ASTM D95 specifically covers determination of water in petroleum products, tars and other bituminous materials by distillation.
Distillation and Reflux Method
The operator places the prepared sample in a glass distillation vessel together with a suitable water-immiscible solvent. The thermoregulated electric heater then heats the mixture in a controlled manner.
During heating, water and solvent vapours travel towards the condenser. The glass reflux condenser cools these vapours and converts them back into liquid.
The condensed liquid then flows into the graduated receiver. Due to the difference between the liquid phases, water separates from the solvent. The solvent returns to the distillation vessel while the water remains in the measuring section.
Precise Water Content Measurement
The system uses a 10 ml graduated receiver. This allows the operator to monitor relatively small quantities of separated water directly.
The transparent glass construction also makes the separation process easy to observe throughout the test. As a result, the operator can determine when the distillation procedure has reached completion.
A 10 ml receiver is also characteristic of equipment intended for water determination in bituminous materials using the Dean-Stark-type distillation principle.
Controlled Heating System
The electric heater transfers heat to the distillation vessel in a controlled manner. A thermoregulator helps maintain stable heating throughout the test.
Consistent heating promotes continuous evaporation without unnecessary temperature fluctuations. This supports stable solvent reflux and effective separation of water from the sample.
Complete Laboratory Configuration
The LT-AS0106 Water in Bituminous Materials Test Set combines the main components required for the distillation procedure. The system includes a thermoregulated electric heater, glass distillation vessel, reflux condenser and 10 ml graduated receiver.
Its compact dimensions of approximately 20 × 20 × 45 cm make the apparatus suitable for routine laboratory bench use.
Water Determination According to Standards
The test set supports water content determination associated with ASTM D95, ASTM D244, EN 1428, AASHTO T55 and AASHTO T59.
ASTM D95 covers water determination in petroleum products and bituminous materials by distillation, while ASTM D244 addresses testing of emulsified asphalts.
Overall, the LT-AS0106 Water in Bituminous Materials Test Set combines controlled heating, reflux distillation and direct volumetric measurement. Therefore, asphalt and bitumen laboratories can determine water content under practical and repeatable test conditions.
