It consists of three cylindrical moulds 10.16 cm dia x 7.6 cm high with base plates and extension collars, a specimen extractor, two compaction hammers (4.5 kg) a compaction pedestal, a breaking head assembly, a load transfer bar and a 50 kN loading unit.
The motorised loading unit has a uniform rate of vertical movement of 50.8 mm/mnt.
Suitable for operation on 220V, 50 Hz, single phase supply.
The apparatus consists of following:-
Modified Marshal Load Frame, 10,000 kg with 50kN provingring Breaking head assembly with flow meter Rammer for marshal (2 Nos. required) Modified Marshal mould 150mm dia (3Nos.)
Pedestal for holding the mould (1No.) Breaking head assembly 100 mm (1No.) Collar for marshal mould 100 mm (3Nos.) Base for marshal mould (3Nos.) Pedestal for holding the mould 100 mm & 150 mm mould Dial gauge 25 mm travel, 0.01 mm/divn. Proving ring 50 kN capacity
This model reduces uncertainty in mannully recording of the readings load unit and other accessories are the same as supplied in HB 64.05 except that it has digital display unit for indicating of load and flow since the unit is micro processor based it records the flow at maximum load. Serial port. Serial port is a part of the system for Computer communication.
The Unit comprises of
i) Load Frame 25kN cap
ii) Rammers 2 Nos.
iii) Moulds 3 Nos.
iv) Breaking Head assembly 1No.
v) Digital Display
vi) Load Cell 50 kN
vii) Displacement sensor along with flow meter +/- 20mm
This new ‘HEICO’ Compactor automatically stimulates hand compaction as specified in ASTM D-1559 and develops a uniformity in the test procedure. The apparatus consists of a chain drive coupled to the motor through a gear box, and carries a locking device which lifts and releases the hammer through a specified height. Fitted with a counter which trips the motor automatically after 50 or 75 strokes as set on it.
Suitable for operation on 220 V, 50 Hz, single phase supply.
Suitable for 100 mm and 150 mm mould.
For determining the quantity of bitumen in hot mixedpaving mixtures and pavement samples.
It is a portable unit for use in field and laboratory. It consists of a cast aluminium bowl mounted on vertical shaft and a filter paper disc is pressed in between bowl and cover plate by a knurled nut. A whole system is enclosed in a cast aluminium body. There is provision to introduce the solvent through an inlet in housing cover. Complete with 25 filter discs.
Thermometer IP 280 C. Range -6° to +400°C for use with Cleveland Flash & Fire Point apparatus
IS 1195
For determining the hardness number of mastic asphalt for flooring.
It consists of an internally insulated cabinet to the base of which is fitted a water bath having two taps. The bath is heated by an immersion heater and the temperature is controlled with a thermostat at 350+/- 0.50C. A 6.35 mm dia pin is loaded on the specimen by means of a lever to give 31.7 kg. Weight. A dial gauge 0.01 mm x 25 mm is provided to record the penetration of pin into the specimen.
Same as HB64.35 except that it has stepper motor for control of speed and refrigeration system for controlling and maintaining temperature at 27° +/- 0.2°.
IS: 1195
For determining the hardness number of mastic asphalt for flooring.
It consists of an internally insulated cabinet to the base of which is fitted a water bath having two taps. The bath is heated by an immersion heater and the temperature is controlled with a thermostat at 35°+/- 0.5°C. A 6.35 mm dia pin is loaded on the specimen by means of a lever to give 31.7 kg. Weight. A dial gauge 0.01 mm x 25 mm is provided to record the penetration of pin into the specimen.
For determining the resistance of bituminous mixture to stripping of the asphalt from aggregate particles and for judgeing the adhesive capacity of bituminous material. Applied to aggregate fraction passing 9.525
mm sieve and retained on No.8 Sieve.
It consists of a disc on which four bottles are mounted. The disc rotates at a rate of 100 r.p.m. approx. The
sample is kept in bottles and agitated for 15 minutes.The percentage of aggregate stripped is estimated by
visual observation. Provided with a time switch.
Suitable for operation on 220 V, 50 Hz, single phase supply.
For determining the deflection of flexible pavements under the action of moving loads.
The apparatus consists of a 365 cm long aluminium beam in two halves arranged to give the lever arm ratio of 2:1. Provision is made for levelling the apparatus. An anvil and a probe are fixed in opposite directions on the beam. A buzzer is provided for removing friction in the bearings. For movement of the assembled beam to different test points on the same pavement and clamping, spring loaded clamp is provided. The beam can be levelled by fine and coarse adjustments provided for the purpose.
For fast and accurate measurement Digital Benkelman beam is used for the measurement of deflection under load. It has a digital gauge with an accuracy of 10 microns.
IS: 1834
For determining the extensibility of sealing compound.
It has a loading unit for applying tension on the test specimen at the rate of 3 mm/hr. Suitable for operation on 220 V, 50 Hz, single phase supply.
A four piece metal mould for jointing compound, two clamping strips & screws, one base plate for the extension jig and the jointing compound moulds. One extension jig, one mould with base plate for cement block and one bath with a drain cock.
