The test method is used for determining the depth of indentation of mastic and rolled asphalt, when force is applied via a cylindrical indent or pin with a circular flat-ended base. The maximum nominal size of aggregates in the mix is less or equal to 16mm. The test can be applied both on 70mm approx. cubes or Marshall samples.

The model incorporates some improved features increasing the user-friendliness and the operability of the machine, like the new weight positioning system, allowing in a very user-friendly and precise method to pass from unload to preload phase, then to load phase without the need to add/remove weights from the structure, the four-columns frame structure, granting a precise weight positioning, the piston position indicator, making easier the adaptation of the penetrometer to different height samples (70mm cubes, Marshall specimens) and the water drain facility at the end of the test.

Main Features:

New weight positioning system, allowing in a very user-friendly and precise method to pass from unload to preload phase, then to load phase without the need to add/remove weights from the structure.

Stainless steel water bath included, for sample conditioning.

Water drain with drainage pipe included in the machine.

Four-columns frame structure, with high stiffness.

Piston position indicator, making easier the adaptation of the penetrometer to different height samples.

Technical Specifications:

A range of accessories to create 70 mm mastic asphalt cubes and a water temperature controller are available including the Digital immersion heater-agitator to heat water at the testing temperature conforming to Standard (22 or 40 °C).

The asphalt indentation penetrometer is supplied with a stainless steel water bath, 500 N weights, interchangeable piston 1 and 5 cm2, 30 x 0.01 mm dial gauge, steel plate with dial gauge holder. 

Dimensions (wxdxh): 430x530x955 mm (700 mm without weights)

Weight approx.: 115 kg.
