BITUMEN TESTING instruments
We have applied our expertise in Advanced Bitumen Testing to manufacture a complete range of dynamic and static Bitumen Testing Equipment. Our advanced machines and equipment are trusted by highways departments, national laboratories, universities, asphalt producers, oil companies, paving contractors and consulting engineers worldwide.
BITUMEN EXTRACTOR
For the determination of Bitumen percentage in Bituminous mixtures. It has a removable precision machined aluminum 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. Learn More
CENTRIFUGE EXTRACTOR
Centrifuge Extractors provide efficient and reliable quantitative determinations of bitumen content in hot-mix asphalt specimens.
The precision machined and balanced inner aluminum bowl assembly quickly lifts out of the sealed housing for efficient specimen handling. Rotation speeds up to 3,600rpm. The built-in electric brake stops the centrifuge in seconds when the extraction is complete. Filter Paper rings prevent loss of fines during processing. Learn More
MARSHALL STABILITY TEST 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.
Ductility Testing Machine
The Ductility Testing Machine is used to determine the ductility of bituminous materials in a briquette mould by measuring the breaking elongation at a constant speed of 50 mm/min. It is designed for testing 3 specimens simultaneously. The Internal tank is made of stainless steel. The bath is fitted with an immersion heater in order to obtain (in normal conditions), the 25°C test temperature.
RING AND BALL APPARATUS
For determining the temperature at which a sample of bituminous material drops specified distance when heated under prescribed conditions and loaded by 3/8 inch diameter steel ball. Two simultaneous test can be carried out. The equipment is supplied complete with beaker but without thermometer.
FILM STRIPPING DEVICE
To measure the resistance of bituminous mixtures to stripping of the asphalt from the rock particles to evaluate the mineral aggregate. It may be used to judge the adhesive capacity of the bituminous material. Stone screenings for use in seal coats or open graded mixes are usually subjected to this test. The unit consists of a disc that rotates at 100 R.P.M. The disc carries four bottles. Complete with a time switch. Suitable for operation on 230 volts 50 Hz. single phase A.C. supply. Learn More
