Bitumen Testing Instruments






Bitumen Extractor
ASTM D-2172. AASHO T-58, T-164. For the determination of Bitumen percentage in bituminous mixtures. It has a removable precision- machined aluminium rotor bowl mounted on a vertical shaft. A filter paper disc is pressed in between the rotor bowl and cover plate by tightening a knurled nut. The bowl assembly is enclosed in a housing mounted on a cast body. The manually operated unit can be used both in the field and laboratory. In the manually operated unit, the gears are enclosed in a cast body. The solvent may be introduced tests through a cup on the housing cover.

Electrically Operated. Suitable for operation on 230 volts, 50 HZ, single phase, A.C. supply. Rest operation same as above.

Milestone Instruments
Automatic Compactor for Bituminous Mixes
CODE NO. - NTI-BTI-05
Automatic Compactor for Bituminous Mixes
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.






Milestone Instruments
Universal Cone Penetrometer, Automatic
CODE NO. - NTI-BTI-06
Universal Cone Penetrometer, Automatic
BIS: 1203, BIS: 310 (Part II).
For testing a wide variety of materials such as grease, bitumen, tar wax, polish, food stuffs, rubber, asphalt and pharmaceutical creams. By applying a given force over a given period of time depression is made in the sample which may be measured in tenths of a millimeter and expressed as a penetration number.

Consists of a head support, mounted on a vertical rod which can be adjusted for height. A rack and pinion and pointer provides fine adjustment of needle or cone tip to sample and incorporates a slipping clutch mechanism which makes reading of penetration and subsequent resetting a simple and accurate operation. The dia is graduated from 0-400 in one tenth millimeter subdivision. Complete with plunger and weight of 54 grams, with one needle.
Suitable for operation in 220 volts phase.
