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
20-4034 / 455x300mm

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

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.

Technical specifications:

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)

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.

The automatic system monitoring contains various diagnosis functions and prepares the required diagnosis records. Performance features:

-Integrated programmable controller for controls and recording measured data
