We are offering ductility testing apparatus, ductility testing apparatus:in flexible pavement construction, bitumen binders are used. It is important that bituminous material forms ductile thin film around the aggregates that serves as a binder. The binder material not of sufficient ductility renders pervious pavement surface and leads to development of cracks. Therefore it is important to carry out the ductility tests on bituminous material. 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 50mmminute 25mm per minute at a temperature of 27c 0.5c. specifications: the apparatus consists of a water bath with a thermostatic heater, and a circulating pump to maintain uniform water temperatureone 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 threaded shaft with a clutchthe 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 1mm fixed on the bath with 0 (zero) of the scale towards the fixed plate sidethe rotating shaft has 2 speeds of travel for the bracket, 5 cmmin and 1 cmmin., selected by a clutchwater bath inside is aluminum, it is an insulated water bathwater bath is provided with a draina heater with thermostatic control is fixed inside the water bathcontrol switches for motor, stirrer, heater and indicator lamps are fixed at a convenient place on the water bath, complete with three briquette moulds and one base plate, all made of brassoperates on 230 volts a.c. Single phase accessories: thermometer ip 38 c, range 23c to 27cductility mould with base-plate.
