ROLLER SECTOR COMPACTOR | Asphalt
Roller Sector Compactor 30kn
Roller Sector Compactor 30 kN for the preparation of rolled asphalt samples.
Rigid steel housing with safety door and motor-driven sample guiding unit. Compaction load is applied horizontally by an electronically operated load/displacement controlled system with a roller segment and load and displacement transducers.
Mould and roller segment are equipped with thermostatically controlled electric heating elements.
The whole process is controlled by selectable compaction programmes via Windows software. The user himself can create and memorize own test sequences. The machine and process control is effected by an integrated input/output unit with a touch screen attached by means of a swivel arm. Optionally the input can also be effected using a keyboard.
Sample dimensions available:
20-4030 / 320x260mm
20-4035 / 400x300mm
20-4031 / 410x260mm

HAMBURG WHEEL TRACKER | Asphalt
Hamburg Wheel Tracker
Advanced asphalt performance testing.
Wheel Tracking Test Apparatus air/water small wheel for asphalt samples. The apparatus consists of a steel plate casing with stainless steel interior 1.4301 and hinged cover with viewing glasses.
Two measuring places with rolling wheel units guided in precision bearing elements and driven by a frequency-controlled motor with omega-synchronous-belt-drive are installed. The load is applied via a lever system. The inner chamber can be heated either with water or with a heating system.
To enable the installation of samples into the testing place, both rolling wheel units can be stopped in a parking position outside the testing area. The two sample base plates of the machine are prepared for the installation of either mould spanner sets (20-4020..23) or plaster moulds (20-4015..16). Included are two easily interchangeable rolling wheels with rubber coating.
Stainless steel rolling wheels 20-4000E100 are available on request. Two motorized lifting units controlled by the integrated software are used to sink down the wheels at the beginning of a test and to lift them up afterward. The whole process including heating, registration of test temperatures, number of overrollings and tracking depths is software controlled with the possibility of print-out and selectable testing programmes. The user himself can create and memorize his own test sequences and programmes.
Supplied with integrated input/output unit with a touch screen. Optionally the input can also be effected using a keyboard. Mould spanner sets 20-4020..23 or plaster mould sets 20-4015..16 are not included and have to be ordered in addition.
AUTOMATIC DIGITAL PENETROMETER
Automatic Digital Penetrometer
For determination of the needle penetration.
The penetration depth of the penetration needle is determined with an electronic position measuring system, which is decoupled from the plunger during the test. An influence on the load and friction is excluded, because of this the free guidance of the plunger.
The run-up and touch down of the needle are carried out automatically via the measurement system. Manual joystick mode is also possible. Then the plunger is enabled by an automatic device and blocked again after the testing period. The test result is displayed on the graphical touch display. The plunger can easily be removed to calibrate its weight.
Measuring range: 0-300 (equivalent to 0-30 mm)
Resolution: 0,01 mm
Test load: 100 g (plunger 97.5 g + 2.5 g penetration needle)
Test time: free (adjustable from 0,01 second)
EN 1426 – EN 13880-2/3 – ASTM D 5 – AASHTO T49
ASPHALT ANALYZER PURE
Extraction and binder content determination of bituminous materials begins here. Bituminous material (up to 3.5kg) is weighed into a sieve drum and placed into the washing chamber.
User selects the needed amount of washing and drying cycles and materials will be automatically washed and separated into aggregates, mineral filler and binder under use of solvents and ultrasonic sound separation. The aggregates remain in the sieve drum.
Mineral filler is separated from binder and solvent in the centrifuge unit.
The mineral filler is collected in the centrifuge cup and the binder-solvent mixture is concentrated in the recovery unit by distillation. The recovered solvent is collected in the recovery chamber. Mineral aggregates and filler are dried in the machine and are provided for weighing and the determination of the grading of the bituminous mixture.
The Pure Module is equipped with indirect heating system, which allows a careful and safe handling of the used solvents which are recycled after each extraction.
Asphalt LABORATORY MIXER

BENDING BEAM RHEOMETER
BBR Bending Beam Rheometer. Test System for Determination of Flexural Creep Stiffness of Asphalt Binder at low temperatures. The flexural strength, among other things, is determined in order to evaluate the behaviour of asphalt binder and similar products at low temperatures.
The bending beam rheometer enables users to determine these material properties comfortably. The deflection of the specimen is measured for this purpose with a resolution of 1µm. The test force is regulated with an accuracy of 1 mN. This makes the determination of the flexural strength possible with reproducibility of 1% independent of the operator. The specimen unit is moved by an electromotor and makes fitting and removing the specimens uncomplicated and simple. Automatic, software-controlled operating and standardised evaluation and representation of the findings.

For determination of the Softening Point of Bitumen.
With glass-ceramic plate, halogen radiator for heating and magnetic stirrer with adjustable speed built-in underneath.
Operation is via a touch panel. A microprocessor-controlled regulation with continuous temperature measurement in the beaker ensures a standard-compliant temperature rise of 5 K/min. The temperature rise can be monitored in real-time on the touch display.
The passage of the balls is detected by a light barrier on the right and left and the respective temperature value is displayed digitally. At the same time, the difference between sample 1 and 2 is output. The test data is stored in an internal protocol and can be called up at any time in the unit or transferred via a USB interface.
Three test modes can be preselected, one for water from 30 to 80° C and one for glycerol from 80 to 150° C. Besides, we offer an optional test procedure for silicone oil from 80 to 200°C.
