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.

Marshall Apparatus
Marshall Apparatus
For the measurement of the resistance to plastic flow of cylindrical specimens of bituminous pouring mixture loaded on the lateral surface. This is for use with hot mixture containing asphalt or tar and aggregate up to 25 mm maximum size.
The equipment comprises of following:

Milestone Instruments
Automatic Compactor for Bituminous Mixes
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
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.

Say bolt Viscometer
It is used to determining the viscosity of fuel oil and lubricating oil (thin and thick). The unit consists of stain less steel bath oil cup that centrally placed in water bath. The bath has a lid, which contains a water-cooling tube. Two handles with two starrier blades, the thermometer soaked and a straight heater, stirring is done by turntable arrangements. To operates on 220 volts AC 50 HZ.

Carbon Residue, Conradson type
It is useful to determine amount of carbon residue when an oil is evaporated under specified conditions. The carbon residue values of crude oil, residual etc. These are useful in the manufacture of various lubricants. The apparatus consists of spun sheet iron crucible 25cc capacity. Sheet iron hood and sheet iron block on a stand, gas burner.
a) Conradson carbon residue single test apparatus
b) Conradson carbon residue four test apparatus with gas burner

Cloud & Pour point Apparatus suitable for single test with insulated body
The pour point is the lowest temperature at which the oil will just fail to flow. The apparatus consists of cooling bath made of stainless steel sheet and stand unit drain plug and cover with provision for fitting thermometer and filling aperture for adding freezing mixture.

Cleveland Flash & Fire Point Apparatus
This apparatus is used for determination of flash and fire point of petroleum products. The apparatus consists of a cleveland Flash Cup made of brass, Gas Test-Jet Assembly, pivoded from a Cast Cup Platform which is fixed to a Heating Bath. Energy Regulator to regulate rate of rise in temperature. Suitable for operation of 230 V, 50 Hz, single phase, AC supply.

Milestone Instruments
Ring And Ball Apparatus
Ring And Ball Apparatus ( As Per I.S. 1205)
For determining the temperature at which a sample of bituminous material drops specified distance when heated under prescribed conditions and loaded by 8 mm. diameter steel ball. Two simultaneous tests can be carried out. The equipment is supplied complete with beaker but without thermometer.
