Bitumen Testing Equipment

Product Details:

Centrifuge Extractor this is used for a quantitative determination of bitumen in hot-mixed paving mixtures and pavement samples. The centrifuge extractor is a safe, portable, corrosion-resistant model, which can be used both in the field and the laboratory it consists of a removable cast aluminum rotor bowl mounted on a vertical shaft. A filter paper disc is pressed in between the rotor bowl and cover plate by a knurled nut. The bowl assembly is enclosed in a housing mounted on a cast aluminum body The gears operate in oil bath with splash lubrication. Complete with 25 filter discs.  The motor drive gives 3500 r.p.m. to the rotor bowl. Operation on 230 Volts Single Phase, 50 cycles. A.C. Supply.

Product Details:

Consists of two conical hoppers and a cylinder mounted on a rigid metal frame The lower openings of the hoppers are fitted with hinged trap-doors for release and during the fall of material.Complete with trowel  tamping bar 0-60cms long x 16mm dia.

Product Details:

This mixer has three speed constant mesh gear box driven by an electric motor fully enclosed within the transmission case.  The low speed drive automatically comes into action when either on light loads, speed changes may be made without switching off the motor, but on heavy load the motor should be switched off. A gear train to provide smooth gaer change and also protect the transmission machanism.  Ball bearings are used throughout which together with all gears run in special lubricant requiring no attention for several  years.  All the machanism from the beater shaft to the motor is enclosed.  Supplied complete with stainless steel bowl fitted with handle beater and hook. Fitted with heating Jacket thermostatically control.

Motor rating : 0.5 H.P. Operation: 230 volts single phase, 50 cycles, AC supply.

Product Details:

It is a motor driven mechanical compactor useful for soil compaction into 100mm or 150mm dia moulds.  Two sets of rammers are provided, one of 2.6 kg, and arranged for 310mm drop and other 4.9 kg and arranged for 450 mm fall. For Compaction soil into 150 mm dia moulds, 100 mm face dia rammers having weights 2.6  kg and 4.89 kg are used. Where as for 100 mm dia moulds they are of 50mm dia. The rammer assembly is provided with  a ratchet and pawl arrangment to lift it from the top of the soil layer.  When the rammer reaches the required height the pawl release the rammer which falls freely on soil surface.  The release mechanism is operated by an arm moving up and down which is connected to a reduction gear coupled to the motor through another arm. An automatic blow counter fitted to the compactor is used to set the number of blows.


The base plate of the specimen mould is to be fitted to the rotaing base plate of the instrument which makes 1/5th revolution per stroke.  The equipment is suitable for operation 230 volts, 50 cycles, single phase, A.C. supply  Moulds are to be ordered separetely.

Bituminous Mixer To Stripping Of The Asphalt From Rock Particles
And Is Generally Used To Evaluate The Mineral Aggregate.
It May Be Used To Judge The Adhesive Capacity Of Bituminous
Material. Stone Screening For Use With Seal Coats Open Graded
Mixes Are Usually Subjected To This Test. The Test Is Applied To
The Aggregate Fraction Passing The 9.525 Mm Sieve And Retained
On No. 8 Sieve.
The Film Stripping Device Consists Of A Disc Of Which Four Bottles
Are Mounted. The Disc Rotated At The Rate Of Approximately
100 R.p.m A Time Switch Is Provided.
Suitable For Operation On 230 Volts, Single Phase, A.c. Supply.
The Sample Is Kept In Bottles And Agitates For Fifteen Minutes
The Percentage Of Aggregate Stripped Is Then Estimated By
Visual Observation.

Product Details:

Used to determine the grade of bitumen. The Standard Penetrometer tests determine the consistency of bitumen for the purpose of grading Depth in units 1/10 of a millimeter to which a standard needle having a standard weight will penetrate vertically in a duration of five seconds at a temperature of 25 ºC determines penetration for graduation. Consists of a vertical pillar mounted on a base provided with leveling screw The head together with dial gauge rod and cone (or needle) slides on a pillar and can be clamped at the required height. A rack and pinion and pointer assembly provide adjustment of needle or cone tip to sample. It incorporates a slipping clutch mechanism which makes the reading of penetration and subsequent resting a simple and accurate operation The dial is graduated in 400 1/10th mm sub-divisions, and the red needle pointer against black figures makes for easy reading. Supplied complete with one 50 gram weight, and one 100 gram weight and one needle.

Accessories:

• Penetrometer Cone: made of Gunmetal and is fitted with a hardened and ground detachable steel, tip and a stem, Total moving weight is 150 0.1 gram.

Rajco Automatic Standard Penetrometer:

• Same as above RSEP-180, but supplied with transistorized timer and electro-magnet incorporated in the clutch mechanism to accurately control penetration time to exact five seconds.
