Field Density & Bearing capacity

In-situ measurements of soil density are often performed through volume sand replacement method or balloon method with water. CONTROLS offers a complete range of equipment fully compliant with ASTM, AASTHO, NF and BS Standards. Other products for measuring in-situ such as Surface Soil Samplers and Piston Volumometer density are also available.

Bearing Plate Apparatus are used for estimating the bearing capacity of a soil under field loading conditions for a specific loading plate. They also cover load tests on soil and flexible pavement components, for use in evaluation and design of airport and highway pavements. CONTROLS provides a vast range of bearing plate capacity equipment fully conforming to BS, ASTM and CNR standards, available as either analog, digital or electronic versions.

Standards ASTM D1556 AASHTO T191 NF P94-061-3

Send replacement cones 35-T0128, 35-T0129 and 35-T0133

Description

The verification of the degree of compaction can be determinate on site by a simple procedure consisting essentially in removing and weighing a part of compacted soil and replacing in the hole with sand by a simple apparatus recording the volume of sand and then calculating the density of the removed soil.
We propose three models to be selected conforming to the size of grained soils. The 35-T0133 bigger version is recommended for gravel and coarse-grained soil.
The set includes the Double cone, two plastic sand jar and metal base plate except the 35-T0133 model which is supplied with one acrylic sand container only.
The 35-T0129 6.5” dia. (165.1 mm) model can be completed with a calibrating container. See accessories.

Main Features

The PReSBOX produces a prismatic specimen with nominal dimensions of 450 mm (lenght) x 150 mm (width) x 120 to 185 mm (height)

Asphalt prisms prepared in the PReSBOX compactor can be sawn or cored to produce 4-6 prismatic beams or 1-4 cylindrical specimens

The PReSBOX can be operated by a single person Produces specimens with excellent air void distribtion and particle orientation

Designed for an easy unlocking of the compaction mould, facilitating an effortless speciment extraction at safe height, handling and user safety

Surface Soil Sampler, ASTM/CNR

Used to take a standard volume sample from the ground in order to establish the in-situ density.

Standards ASTM D2937 CNR N°22

35-T0135 surface soil sampler

Description

Used to take a standard volume sample from the ground in order to establish the in-situ density of the soil. The apparatus consists of a 5 kg sliding weight drop hammer, which falls freely onto the driving head situated on top of the sampling tube ID 73×66 mm high. Made from steel protected against corrosion.
Weight approx.: 10 kg

Used to take a standard volume sample form the ground in order to establish the in-situ density.

Standards BS 1377:9

35-T0137

Description

The core cutter is driven into the soil using the driving hammer. Then the core is dug out, trimmed, weighed, dried and the density and moisture content calculated. Made of steel protected against corrosion. The set includes core cutter, driving dolly and driving rammer. Two versions available: dia. 100x 130 mm high and dia. 150×180 mm core.

Main Features

Completely electromechanically operated

Possibility to program user defined procedures as free combination of load and displacement (or combined) controlled cycles

Completely electromechanically operated

Conforming to EN 12697-33, 5.2 method and ASTM D8079

21” All-in-one touchscreen PC controlled , PC and software included

Includes the compaction procedure defined in the brand new EN 12697-33 method 7.3, providing at the beginning a controlled displacement compaction which can grant a flat surface followed by a load compaction phase , which can replicate the real compaction on the road surface

Base and foot adjustable heating system available as option

Mould dimensions: 500 x 400, 500 x 300, 400 x 300, 300 x 300 and 320 x 260 mm, 195 mm height

Compaction direction in the longest (major) mould dimension to obtain specimens of the proper length conforming to Standard

Vertical balanced of sliding cover for easy access and complete three side view

Maximum compaction load 30 kN

User defined controlled linear speed up to 300 mm/sec and adjustable pause at the mould inversion point

Ideal for producing test beams for 4-Point bending (EN 12697-24, EN 12697-26, AASHTO T321) and slabs down to 38 mm

Vibrating roller option, adjustable from 10 to 50 Hz

PRO-COMPACT* closed loop control slabs Customization of compacting cycle which can be saved and recalled from the database
*PRO-COMPACT closed-loop is an innovative mechanical and electronic control that combines orthogonality of the load, pendulum motion of the head and sinusoidal non-friction forward-reverse carriage movement. This results in an optimally compacted sample that features Planarity Regularity and hOmogeneity (PRO). The combined load/displacement compaction procedure provides at the beginning of the test a controlled displacement compaction, which can grant a flat surface of the compacted slab, followed by a load compaction phase, which can replicate the real compaction on the road surface.
