AMPT - Asphalt Mixture Performance Tester

Circulating digital water bath, 56 liters cap. (mod. 76-B0067/B)

Water baths are needed to condition Marshall and other asphalt specimens before mechanical testing. Several models are available with different sample capacities and temperature ranges. You can also select a model with cooling unit, for improved temperature stability and extended temperature range, starting from 5°C. All water baths are made of stainless steel.

Circulating Water Bath With Cooler Unit for Marshall

Multi-purpose digital water bath, fit with cooler unit and recirculating water system.

Standards EN 196-1

65-D1409/A
Description
 
This multi-purpose digital unit, fit with cooler unit and recirculating water system, is used to condition in water asphalt specimens for Marshall and Indirect tensile test. The EN 12697-23 covering the Determination of the indirect tensile strength of bituminous mixtures, prescribe a water conditioning temperature of 5°C or from 5 to 25°C which are obtainable with a cooling system. All the other standards require conditioning temperatures from 25 to 60 °C. This unit can also be used for many applications either for Asphalt or for Cement testing for curing in water cement specimens 40x40x160 mm, and for storing the hydrated samples at a temperature of 20°C (EN 196-8). Internal surfaces are polished stainless steel with a sheet steel insulated outer case. The cooler unit is located under the water bath. Complete with re-circulating unit for temperature uniformity.
