Code : B038
Standard Method : EN 12697-22 | BS 598:110 | Comparable to NF P98-251-1, P98-251-4
This machine is used in laboratory, for evaluating the deformation (rut) depth of a bituminous mixture subjected to cycles of passes of a loaded
rubber wheel under constant and controlled temperature conditions. To perform the test, a wheel tracking apparatus is used to simulate the
effect of traffic and to measure the deformation susceptibility of the bituminous sample.
Matest wheel tracker fully satisfies both EN 12697-22 and BS 598:110 specifications and may perform the test following both procedures A
and B, clearly specified by the EN Standard.
MAIN FEATURES
Accepts mould up to 500×400 mm,180 mm high.
Perfectly fit for slabs made by Matest ARC Asphalt Roller Compactor.
Continuous realtime rut depth measurement.
Three temperature probes for temperature control and adjustement.
Automatic control of machine and test.
Realtime display of: number of cycles,rut depth, temperatures.
Realtime cycle rate also displayed when using a serial connection to PC
TECHNICAL SPECIFICATIONS
# Travel of the table: 230 ± 5 mm
# Table cycle frequency: adjustable 15 to 40 cycles per minute.
# Hard rubber tyred wheel having outside diameter 200 mm
# Wheel load on the sample:
-
700N ±10N (EN 12697-22) or 520N (BS 598:110)
-
The load is applied on the sample through a lever.
-
The effective load applied on the sample can be adjusted by micrometrical weights positioning.
# Continuous real time rut depth measurement (penetration of the wheel into the sample) through a linear transducer 40 mm travel by 0.01 mm accuracy.
# The test frame is made of robust aluminium alloy and it is contained in a climatic cabinet with adjustable temperature from 30 to 65 °C ± 1.0 °C The cabinet is equipped with two doors with insulated glass for inspection
# The sample table has dimensions: 400×390 mm and can accept
rectangular slabs of several sizes:
-
305×305 mm, 50 or 100 mm high
-
400×305 mm, 50 or 100 mm high
-
200 mm dia. core samples, 50 mm high
The sample confinement frames are not included and have to be ordered separately (see accessories)
# Matest wheel tracker accepts also samples with dimensions up to 500×400 mm, 180 mm high (this mould can be compacted with Matest ARC: Asphalt Roller Compactor)
# The machine is supplied complete with adaptors for a correct mould positioning and locking
# The wheel tracker is equipped with 3 temperature probes:
-
probe, connected to the thermoregulator, for the control and adjustment of the cabinet temperature.
-
probes for temperature measurement inside the specimen.
