The 50 kN capacity Automatic Marshall Stability Test Machine is used to determine the maximum load and flow values of bituminous mixtures. The machine comprises of a robust and compact two column frame with adjustable upper cross beam. The unit is a bench mounting compression frame with motor and worm gear housed within the base unit. The speed of the lower platen can be adjusted between 6 mmmin to 60 mmmin using the data acquisition and control unit. For safety, the up and down travel of the lower platen is limited the use of limit switches. Rapid adjustment of the platen is controlled using the up and down buttons on the front panel of the machine. The machine can be hand operated by a lateral hand wheel for calibration purposes. The measuring system consists of a 50 kn capacity strain gauge load cell fitted to the upper cross beam to read stability values and the 25 x 0.001 mm linear potentiometric displacement transducer fitted to the breaking head. The Automatic Marshall Stability Machine is suitable for testing 6" dia. 4" dia. specimens conforming to ASTM D5581. Programmable digital gain adjustment for load-cell, pressure transducers, strain-gauge based sensors, potentiometric sensors, voltage and current transmitters.

Ductility is defined as distance in cms to which a standard briquette of bitumen can be stretched before the thread breaks. The briquette is stretched at a rate of 50 mmmin. 2.5mm per minute at a temperature of 27C 0.5C. The Machine is having built in refrigeration system to work a below ambient temperature up to 10C in tropical conditions. The Machine will operate at 27C with control accuracy of 0.5C as per the requirement of IS. The apparatus consists of water bath with a heater, and a circulating pump to maintain uniform water temperature. One half of the briquette moulds is fixed in a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating 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 0-100 cm x 1mm 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 cmmin.and 1cmmin. selected by a clutch. Water bath inside is of stainless steel with insulation and water drain cock . A heater with is fitted inside the water bath. The Temp. is controlled by dual display Microprocessor based Auto Tuning PID Digital Temp. indicator cum controller. Control switches for motor, stirrer, heater and indicator lamps are fixed at a convenient place on the water bath. Complete with three briqutte moulds and one base plate, All supply single phase. As per IS 1208.

Vickers Hardness Tester is simple & accurate in design. It is suitable for measuring the hardness of precision metallic parts with wide testing range from soft to hard & their accurate results are widely acclaimed. These testers strictly conform to 15:1754-1968. Features Tiny indentation allows testing of a precision finished parts. Thin sheet metal are perfectly tested. Because applied load is very small. Motorised loading and unloading cycle. Built-in projection screen to get accurate results.

The machine is used to determine the resistance of aggregate to wear by abrasion. Inadequate abrasion resistance of road-surfacing aggregates means an early loss of the texture depth required to maintain high-speed skidding resistance.

Controls of Pendulum The Pendulum supported in the starting positions is by a self resetting latch. The release mechanism is operated by lever. The Pendulum release latch is operated only when this lever is operated. Strikers & Supporters There are strikers & one combined support available for fitting into the Pendulum & on to the base of the machine for Izod, Charpy test. Changing from one striker to another is achieved simply by fixing the new striker into its position.

Brinell Hardness Test. Rockwell cum Brinell tests consists of forcing an indentor (Diamond Ball) into the surface of a test piece in two steps i.e.first with preliminary test force and thereafter with additional test force and then measuring depth of indentation after removal of addition test force (Remaining preliminary test force active) for measurement of hardness value. These machines are suitable for Rockwell cum Brinell tests. These are motorized digital Hardness Testers having LCD display for easy hardness measurement. The results are displayed in 0.1 Rockwell unit for more accurate measurement. Brinell Hardness measured by using microscope manually.
