Bitumen Testing Equipment

Our outstanding manufacturing facility have enabled us in producing instruments for testing the bitumen. Bitumen in particular is a mixture of organic liquids which are highly viscous, black, sticky, entirely soluble in carbon disulfide. This material is composed of highly condensed polycyclic aromatic hydrocarbons. For testing this bitumen on varied parameters, we use various equipment. Following are the products we are offering under this category:


Bitumen Extractor

We present analog control model with analog controller in base. 1500g capacity, 220V, 50Hz. These are manufactured out of superior quality raw material and this is why it has high resistance in the extreme conditions. These are qualitative and cost effective at the same time.

Ductility Testing Apparatus

It is a very useful equipment for construction industry for conducting ductility tests on bituminous material. It is also equipped with certain accessories.

Bitumen binders are used in flexible pavement construction. It is important for bituminous material to form ductile thin film around the aggregates, which serves as a binder. If the binder material does not have sufficient ductility, it leads to spurious pavement surface and leads to development of cracks. Therefore it is extremely important to carry out the ductility test on bituminous material.

Ductility is defined as distance in centimeters to which a standard briquette of bitumen can be stretched before the thread breaks.The briquette is stretched at a rate of 50 mm /min. +/2.5 mm per minute at a temperature of 27ºC +/0.5ºC.

The apparatus consists of water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature One half of the briquette moulds is fixed on a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating the threaded shaft with a clutch. The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the bath. A pointer fixed to the carrier moves over a scale graduated from 0-110 cm x 1 mm fixed on the bath with “0” (Zero) of the scale towards the fixed plates side. The rotating shaft has 2 speeds of travel for the bracket, 5 cm/min and 1 cm/min. selected by a clutch.

Water bath inside is of S. steel, its is an insulated water bath Water bath is provided with a drain. A heater with thermostatic control is fixed inside the water bath. Control switches for motor pump heater and indicator lamps are fixed at a convenient place on the water bath. Complete with three briquette moulds and one base plate, steel all made of brass operates on 230V A.C. supply single phase.

Ductility mould with base plate made of Gunmetal.


Ductility Testing Apparatus


Marshall Stability Test Apparatus

It is a very important instrument ideal for carrying out marshall stability test of bituminous mixture. It is easy to operate, highly efficiency rate and has high degree of automation.


The apparatus is suitable for conducting Marshall stability test of bituminous mixture. The apparatus can truly judge the fail point of bituminous mixtures to design the match ratio or check the construction quality of bitumen road surface. The Marshall stability of a mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60º C. The test is applicable to hot mix designs using bitumen and aggregates upto a maximum size of 25 mm.

Marshall Stability Test Apparatus


Automatic Bituminous Compactor

Kewil 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.

Benkelman Beam

Benkelman beam is an apparatus, which measures the deflection of a flexible pavement under moving wheel loads. This is a simple device and forms the basis of empirical diagnosis of pavement defects.


Salient Features


  • The equipments is light weight and made of aluminium for easy portability and use at any test location.
  • Length of the benkelman beam is 250cm and net weight is 15kg.
  • The apparatus is compact, unique and possess a telescopic design for quick set up and storage during transport to the test location.
  • The equipment is supplied in two parts for assembling on site with easy Hand Tools.
  • One end of the beam rests at a point under investigation while the beam is pivoted in the centre.
  • The free end carries a dial gauge to record the deflections. The other end is kept on a stable platform.
  • Provided with anti-vibration systems for accurate measurement of pavements.
  • Provided with dial indicator and accessories.
  • The beam is put in contact with the pavement under test between the tires of the vehicles.
  • The measurement of the deflection is carried out when the vehicle passes over the test area.

Utility

  • Direct reading of deflection dial indicators eliminate the need for conversions or calculations during measurement.
  • It is used to measure the deflection of the road surface when loaded by the wheels of vehicles.

Accessories

  •     Wooden carrying case for the benkelman beam
  •     Benkelman indicator gauge, calibration unit, etc.

Applications


  •      Pavement structure analysis
  •      Roadways construction
  •      Road surface deflection measurement
  •      Plate test

Standard Penetrometer

Standard penetrometer is Used to determine grade of bitumen. The penetration tests determine consistency of bitumen for the purpose of grading Depth in units 1/10 of 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 gradation. 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 required height. A rack and pinion and pointer assembly provides adjustment of needle or cone tip to sample. It incorporates a slipping clutch mechanism which make reading of penetration and subsequesnt resetting 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.

Stripping Value Apparatus

Here is an informative page on important features, specifications and applications of Stripping Value Apparatus, used to measure stripping value of bituminous mixture.

This apparatus is used to determine stripping value of bituminous mixture mixes having size 1.0 mm to 75 microns. It is also used to measure the resistance of bituminous mixture to stripping of bitumen from rock particles.

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 samples are 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.
