Ductility Testing Apparatus

We are a leading manufacturer, supplier and trader of superior quality Ductility Testing Apparatus. The apparatus consists of a water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature. These products are manufactured under the close supervision of our experienced professionals using high quality material.

Features:

  • Tough construction
  • Minimal maintenance cost
  • Easy to use

Other Details:

  • In flexible pavement construction, bitumen binders are used. It is important that bituminous material forms ductile thin film around the aggregates, which 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
  • The briquette is stretched at a rate 0 0 of 50mm/minute /-2.5 mm per minute at a temperature of 27 C /-0.5 C

Specifications:

  • The apparatus consists of a Water bath with a thermostatic heater, and a circulating pump to maintain uniform water temperature.
  • One half of the briquette moulds in 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 clutch.
  • The motor and gears to rotate the shaft are housed in a cabinet fixed above the other and of the bath.
