The stand consists of a chassis (11), made of steel profiles, on which there is mounted a temperature-controlled and sealed chamber (1), by means of some glass panels (15), inside the chamber (1) there being disposed an assembly for catching the hydrocarbon pavement mixture sample (5) to be tested, and an assembly (B) for pressing the sample, and also an electric control panel (12) and a forced convection air heater (13) electronically controlled by a thermostat (14), for adjusting the air temperature in the chamber (1).
