Vibrating Hammer

The HR-AS2335 Vibratory Compactor Set is used to prepare the moulded test specimens of bituminous mixtures in loose state by using the vibratory compaction technique.

Such specimens are used to determine maximum density as described EN 12697- 5, bulk density as described in EN 12697-6, void characteristics as described in EN 12697-8, reference density as described in EN 12697-9 or compactability as described in EN 12697-10 for a bituminous mixtures.

The HR-AS2335 Vibratory Compactor Set consists of a Vibrating Hammer, Supporting Frame, Small and Large Tamping Foots and 300 mm Shank.

P.R.D.(percentage refusal density) Split mould is vertically split on one side, foreseen of clamp attachment to the base plate, plated against corrosion, is utilized for determining the degree of compaction of bituminous pavements, for quality control purpose.

The split mould and base plate should be ordered separately.

The set is also used for compaction of proctor and CBR soil specimens.

Supporting Frame for Vibrating Hammer; the sliding mass has a total weight (including hammer and tamping foot) of 37 kg as requested by EN standards.Steel made, plated against corrosion.

CBR Type Modified Proctor Mould (Vibrating Hammer Mould) and C Spanner should be ordered separately.

Automatic Soil Compactor (Economic Model)

Automatic Soil Compactor is designed to compact Standard / Modified and CBR specimens, it ensures an extremely uniform compaction degree, granting reliable and repeatable test results.

The compactor is easy to use, friendly menu driven, of simple and practical maintenance.

Compactor is equipped with programmable digital counter which allows machine to stop at the preset numbers of blows. The height and weight of the rammer is adjustable to suit test requirements. Quality and high accuracy mechanical components grant very long life also under intensive utilizations.

The original lift system of the rammer can be selected at 305 or 457 mm, granting a correct and constant fall height. This automatic blow pattern ensures effective and equal compaction for each layer of soil by rotating the base table, so the mould, in equal steps and travelling the rammer across the mould.

The table rotates the mould in equal steps and the number of blows per layer can be set at the beginning of the test by the digital counter. User defined blow number and in-out distribution is also available. A standard proctor / CBR switch, emergency stop and start push buttons are located beside the blow counter.

The rammer is circular faced. Rammer weight is adjustable to 2.5 kg or 4.5 kg according to reference standard. When compacting specimens in Standard Proctor moulds, the unit operates on a single radius and when compacting specimens in Modified Proctor or CBR moulds, the unit operates on inner and outer radius to obtain even compaction.

The machine is supplied with one rammer and must selected according to the desired Standard (ASTM or EN) (rammers are interchangeable).

Automatic Soil Compactor

Automatic Soil Compactor is designed to compact Standard / Modified and CBR specimens, it ensures an extremely uniform compaction degree, granting reliable and repeatable test results.

The compactor is easy to use, friendly menu driven, of simple and practical maintenance.

Compactor is equipped with programmable digital counter which allows machine to stop at the preset numbers of blows. The height and weight of the rammer is adjustable to suit test requirements. Top quality components and high accuracy mechanical workings grant very long life also under intensive utilizations.

The original lift system of the rammer can be selected at 300 mm, 305 mm, 450 mm or 457 mm, granting a correct and constant fall height. According to the standard used, rammer heads with a diameter of 50 mm or 50.8 mm can be attached to the circular rammer. (The rammer head diameters to be used must be specified at the time of order).

This automatic blow pattern ensures effective and equal compaction for each layer of soil by rotating the base table, so the mould, in equal steps and travelling the rammer across the mould.

The table rotates the mould in equal steps and the number of blows per layer can be set at the beginning of the test by the digital counter. User defined blow number and in-out distribution is also available. Start button, Stop button and Emergency stop button are located beside the blow counter.

The rammer is circular faced. Rammer weight is adjustable to 2.5 kg or 4.5 kg according to reference standard. When compacting specimens in Standard Proctor moulds, the unit operates on a single radius and when compacting specimens in Modified Proctor or CBR moulds, the unit operates on inner and outer radius to obtain even compaction.

Mould selection, number of blows, count of the number of inner and outer drops can be selected as user defined, as well as 4 different programs defined in accordance with the standards from the digital screen mounted on the side of the device.

Noise Reduction Cabinet is available as optional and should be ordered separately.

Proctor Mould And Hammer

Used for determining the relationship between the moisture content and density of compacted soils.

Made of plated steel, includes collar, mould body and base plate.

Rammers are used to compact the soil sample in the Proctor Moulds and made of plated steel.

Different models are available conforming to the relevant standards.

Plastic Limit Test Set

The plastic limit determines the lowest moisture content of a soil, by which a sample can be rolled into threads ∅ 3 mm without breaking the same either longitudinally or transversely.

Supplied with 6 pieces Ø 55 cm x 35 mm Moisture Content Tins, 300x300x5 mm Glass Plate, Ø 12 cm Porcelain Dish, Ø 3 x 100 mm Reference Rod, 100 mm Spatula and Carrying Case.

Liquid Limit Device

Used to evaluate the relationship between the moisture percentage of a soil sample and the number of blows required to close a groove made into the soil; and therefore to determine when a clay soil changes from a plastic to a liquid state.

The device is available in two models:

• Hand operated,

• Motor operated at 120 drops/min speed, ensuring better uniformity and accuracy

Comprises a removable brass cup, adjustable crank and cam mechanism, blow counter and base.

Supplied with Brass grooving tool.

Resilience Tester is used for measuring the resilience of liquid limit device bases. Resilience Tester consists of a clear acrylic plastic tube, steel ball and a small bar magnet. Resilience Tester should be ordered separately.

This test covers the determination of linear shrinkage of soils and indicates the plastic properties of soils with a low clay content.

Shrinkage Limit Test Set

Cone Penetrometer

Semi-Automatic Digital Penetrometer apparatus is used to determine the moisture content at which clay soils pass from a plastic to a liquid state and it is used also for the determination of undrained shear strength.

The penetrometer has a cast iron base with leveling screws, digital penetration measurement gauge 0.01 mm precision, release button and automatic zeroing.

It is provided with lead screw gear arrangement, Leveling screws, and Spirit level. The head can be clamped at any desired height. A rack and pinion and pointer assemble provides fine adjustment of the cone tip to sample. It incorporates a clutch mechanism which makes reading of penetration and subsequent resetting a simple and accurate operation.

Semi-Automatic Digital Penetrometer for Liquid Limit is complete with automatic controller, which automatically releases the plunger by a magnetic device, complete with micrometer vertical adjustment and adjustable electronic timer of the fall time. The penetrometer is equipped with a digital timer, which can be set to the standard 5 second free-fall time or to some other setting for customized tests. When engaged the timer will allow the needle to free fall into the sample for the specific time interval and then lock the needle from advancing while providing a direct reading of the test results.

320 g weight should be added to the 30° angle cone to get a total weight of 400 g for the shear strength test.

The electronic timer allows the user to set up and read the fall time of the needle during testing.
