Wheel Rut Shaper
Wheel Rut Shaper
Ref. Standard EN 12697 – 33
EKE 578:
The apparatus is used to prepare the bitumen specimen for wheel rut testing used in research and road construction. It compacts asphalt slabs to target density in a size of 300 x 300 x 50 mm
The machine has a bearing car which has a mould for sample preparation loaded by rolling wheel vertically. The bearing car moves 300 mm in and out for homogenous compaction of specimen by rolling wheel. The rolling wheel is compacted thru top cover of mould. The bearing car moves in and out on crank shaft, gear wheel with electric shaft mechanism . Automatically controlled compaction , Start and Emergency stop switches are provided in the machine.
Suitable for operation on 415 V, 50 Hz, 3 Phase , AC Supply
Technical Specifications:
• Rolling Wheel Radius : 500 mm
• Rolling Wheel Width : 300 mm
• Temperature : Room Temp. to 200°C
• Pressure : up to 9 bar
• Bearing car speed : 6 rpm
• Distance in & Out : 300 mm
• Timer : 0-999 rounds (Can be set)
• Mould Size : 300 x 300 x 50 mm
Wheel Rut Tester
Wheel Rut Tester
EKE 579:
The wheel tester is used to determine the resistance ability to wheel tracking at high temperature of bituminous combined material.
The machine has two main parts i.e testing machine and constant temperature cabinet, temperature is controlled by PID controller. This consists essentially of a loaded wheel, which bears on a sample head on a moving table. The table reciprocates with simple harmonic motion. The wheel is fitted with a solid rubber tyre and moves at a speed of 42 +/.1 rpm and the sample table is fitted with a locking clamp for 230 +/- 10 mm. the machine is also provided a moving beam and balance weight to adjust the tyre position on and off the specimen at the beginning and at the end of the test. The pressure between table and specimen is ensured at 0.7 Map with the leverage effect of moving beam. Further come temperature sensor is provided near the specimen to maintain the temperature of the cabinet. The test is automatically controlled by a data acquisition and processing system with large graphic display to monitor in real time number of cycles, rut depth and temperature and time displacement graph.
Suitable for operation on 415 V, 50 Hz, 3 Phase , AC Supply
Technical Specifications:
• Test Wheel Speed : 42+/- 1 rpm
• Moving distance of sample table : 230 +/- 10 mm
• Rubber hardness of wheel : 78 +/- 2 at 60°C
• Specimen Size : 300 x 300 x 50 mm
• Displacement measuring range : 0-30 +/- 0.1 mm
• Max. pressure applied on specimen : 0.7 +/- 0.05 Map
• Temperature of cabinet : Room Temperature to 80 +/- 0.5°C
