Ductility Testing Machine.
| |
|
| Used for determining the ductility of asphalted bitumen and fluxed native asphalt cutback bitumen and blown type bitumen.
Ductility is defined as distance in centimeter 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 / min at a temperature of 27º C ± 0.5º C.
The apparatus consists of a Water Bath having inner chamber made of Aluminium and fitted with heater and a circulating pump to maintain uniform temperature. Temperature is controlled by a Thermostat / Digital Temperature controller cum Indicator.
One half of the briquette moulds is fixed on a fixed plate in the water bath and 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 water bath. A pointer is fixed to the carrier moves over a scale graduated from 0 - 100 cm x 1 mm fixed on the bath with "0" (Zero) of the scale towards the fixed plate side. The rotating shaft has two speeds of travel for the bracket, 50 mm / min and 10 mm / min, which can be selected by a clutch. Complete with three briquette moulds and one base plate, all made of brass. Suitable to operate on 230 Volts, 50 Cycles, Single phase and AC supply. |

| The Specimen Holder to hold 100 mm Dia Mould is fitted on the top of the pedestal. |
 |
| |
|
|
Marshall Mould Compactor-Automatic. For 100mm Dia Moulds.)
| |
|
This equipment is to speed up the process to cylindrical specimens for Marshal Stability Testing Machine with ease and accuracy. The compactor has been designed to simulate hand compaction as described in ASTM D 1559. This machine compact the samples automatically and stops when desired preset numbers of blows have been completed. The compactor gives uniform and accurate marshal moulds for reliable testing.
It is a motor driven mechanical compactor useful to compact 100 mm Dia moulds. It is fitted with a compaction rammer of 98 ± 5 mm Dia, weighing 4.5 Kg with a free fall of 457 mm. The rammer assembly is provided with a ratchet and pawl arrangement to lift it from the top of the test samples. When the rammer reaches the required height, the pawl releases the rammer, which falls freely on the test specimen. The release mechanism is connected by an arm moving up and down, which is connected to a reduction gear coupled to the motor through another arm. An automatic Electronic blow counter is used to set the desired number of blows. The Compactor is supplied complete with wooden pedestal. Suitable work on 230 V, 50 Hz, Ac Single Phase |
