Compliance Standards
IS 1208-1978 (R.A.2013),AASHTO T 51,ASTM D113,EN 13589 & EN 13398,JIS K 2207
Applications
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 25°C ± 0.1°C. The Machine is having built in refrigeration system to work a below ambient temperature up to 10°C in tropical conditions. The Machine will operate at 25°C with control accuracy of ± 0.1°C as per the requirement of IS.
Details
The apparatus consists of water bath with a heater, and a circulating pump to maintain uniform water temperature. one half of the briquette molds is fixed in a fixed plate in the water bath, the other half of the briquette mold 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 cm/min and 1cm/min, selected by a clutch. Water bath inside is of stainless steel with insulation and water drain cock. A heater which 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, Working on 220/230 V AC single phase.
