This apparatus is used to prepare the bitumen specimen for wheel rut testing used in research and road construction. It compacts asphalt slabs to a target density in a size of 300x300x50 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 pneumatic cylinder and has in built heater to heat up the specimen thru top cover of mould. The bearing car moves in and out on crank shaft, gear wheel with eccentric shaft mechanism. Automatically controlled compaction, Start and Emergency stop switches are provided in the machine.
