Bitumen Testing Equipment
Our range of Marshal stability test apparatus reduces uncertainty in manually recording of the readings load unit and other accessories are the same as supplied in HB64.05 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.
This range comprises of the following:
|ES-077 Everest Scissors Ductility Testing Machine : IS : 1208|
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 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 aluminium/ 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.
