Automatic Compactor for Bituminous Mixes

• Rugged construction to withstand hard work
• Fully automatic and easy to operate
• Uniform compaction
• Automatic Blow Counter

The Automatic compactor eliminates the laborious process of manual compaction and an even degree of compaction is achieved. The drive mechanism lifts the weight of 4.5 kg and drops it through a correct height of 457 mm. The rammer foot is removable, which facilitates preheating
A compaction pedestal with specimen holder is fixed to the base. An automatic blow counter enables the number of blows to be preset before each test and automatically stops the machine on completion. Suitable for operation on 230 V, 50 Hz, single phase, AC supply

Bituminous surfaces exposed to varying temperature conditions undergo a great deal of expansion and contraction. Therefore, an important characteristic of the binder is its ductility and the degree of ductility has an effect on the cracking of bituminous surfaces caused by traffic stress. The ductility of bitumen is expressed as the distance in centimetres to which a standard briquette can be elongated before the thread thus formed breaks under specified conditions.
A molten bitumen sample is poured into a standard mould, allowed to cool to room temperature and then placed in a water bath so that the briquette can be brought to test temperature before mounting in the testing machine.
