Soil and stone

CBR Test equipment 50 kN

standards: ASTM D 1883 AASHTO T 193 UNI 10009 BS 1377 BS 1924

We offer models for continuous processes with a variable speed (T 052/E), 6-speed model (T051) and a two fixed-speed models (T005 and T005/B) as well as a hand-operated machines for C.B.R. in-situ tests (the test that can be done outside the laboratory).

Special features of the multitest device are variable speed, operating within a continuous  range (0.01 to 52.0 mm/min). They are also able to perform tests controlling both the load and deformation. They can therefore be used for other types of testing, such as for asphalt (Marshall test and indirect tensile test), compression tests on asphalt-cement and cement mixtures for stabilization and further flexural tests on concrete, mortar, bricks, natural stone, concrete roofing, tiles as well as for triaxial tests on soil.

Proctor Compactor – Automatic test equipment for C.B.R. test

EN 13286-2, UNI 10009, CNR 69, ASTM D 558, ASTM D 559, ASTM D 560,
ASTM D 698, ASTM D 1557, ASTM D 1883, BS 1377, BS 1924.

This device eliminates the laborious and above all inconsistent hand compaction of manual work at the testing of volatile material.
The machine is controlled by a microprocessor with an electronically controlled panel.
The number of blows is recorded on a digital display.

Plate bearing test equipment

ASTM D 1194, ASTM D1195, ASTM D 1196, BS 1377, C.N.R. N. 146 S.N.V. N. 70317

The range is wide and includes devices of various capacities from 50 up to 500 kN as well as models for performing overlay tests on piles with the capacity from 1000 up to 2500 kN.

Device for relative density tests of loose materials

ASTM D 4253 ASTM D 4254 EN 13286-5

Used for soils containing up to 12% (of the weight) of loose material passing N º 200 (0.075 mm) sieve. The method uses the vibrating compaction to obtain maximal density and pouring to obtain minimal density.

Digital point load device

ASTM D 5731

A portable device that can be used both in a laboratory as well as and in situ to verify the rock strength index of samples or probes with a diameter up to 102 mm. The values required for calculations of the rock strength index are the failure load and a distance between the conical points.

 

Triaxial testing device using HOEK cells

An automatic pressure device for testing pressure is used in combination with a compression testing machine /see the tests for concrete/. Hoek cells are completed by grabbing tools needed for testing. The device is supplied with a set of 5-6 tools in different sizes and with several plates.
