-ASTM D-2172.AASHO  T-58, T-164. For the determination of  Bitumen  percentage  in     Bitumenous 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 during tests through a cup on the housing cover.

Suitable for operation on 230 volts, 50 Hz., single phase, A.C. supply.

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. 

1203, IS 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.

Sizes:
2.75 Meters long(2% & 3%)
3.50 Meters long(3%)
or any sizes
as per specifications desired

For determining of asphalt, cut bitumen and blown type bitumen.It consists of a bath thermostatically controlled with inlet and outlet taps. Fixed and movable brackets are so positioned that specimen is submerged in water throughout. The rates of pull of 50 mm/min. and 10 mm/min. are incorporated. A clutch arrangement is made to stop the movement of the movable bracket when rupture of the specimen is noticed. Suitable for operation on 230 volts, 50 cycles, single phase, A.C. supply. Complete with three moulds and plates supplied mounted on the apparatus but without thermometer.

For determining the temperature at which a sample of bitumenous 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.

To measure the resistance of bituminous mixtures to stripping of the asphalt from the rock particles and is generally used 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 test is applied to the aggregate fraction passing 3/8 inch sieve and retained on No.8 sieve. It consists of a disc rotation at a speed of approximately 100 r.p.m. Disc carries four bottles. Complete with a time switch. Suitable for operation on 230 volts, 50 Hz., single phase, A.C. supply.
