Compaction Related

Test - In-situ density sand replacement (small cone), dia.100mm

Method - BS1377: Part 9, 1990, 2.1, 

This is the most widely used method for determining the in-situ density of earthworks layers by direct measurements of mass and volume.  The method is applicable for natural or compacted fine to medium grained soil layers up to 150mm thick.  

As a compaction control, the test is normally required with laboratory compaction test (2.5 kg or 4.5 kg rammer) to determine the degree of site compaction relative to laboratory maximum dry density and optimum moisture content. The laboratory test that is charged separately and can be carried out at the Laboratory's permanent facility (as above address) is as follows:

BS1377: Part 4, 1990, 3.3 (2.5k rammer) or/and BS1377: Part 4, 1990, 3.5 (4.5k rammer)

Test - In-situ density sand replacement (large cone), dia.200mm

Method - BS1377: Part 9, 1990, 2.2  

This is the most widely used method for determining the in-situ density of backfill layers (eg. granular sub base- crusher run) by direct measurements of mass and volume.  The method is applicable for natural or compacted fine to coarse-grained soil layers exceeding150mm, but not exceeding 250mm in thickness.  

As a compaction control, the test is normally required with laboratory compaction test (2.5 kg or 4.5 kg rammer) to determine the degree of site compaction relative to laboratory maximum dry density and optimum moisture content. The laboratory test that is charged separately and can be carried out at the Laboratory's permanent facility (as above address) is as follows:

BS1377: Part 4, 1990, 3.4 (2.5k rammer) or/and BS1377: Part 4, 1990, 3.6 (4.5k rammer)

Test - In-situ density core cutter, dia.100mm

Method - BS1377: Part 9, 1990, 2.4

This method may be less accurate than the sand replacement method test. It is used if speed is essential and the soil is sufficiently soft and well compacted for the cutter to be driven easily. As a compaction control, the test is normally required with laboratory compaction test (2.5 kg or 4.5 kg rammer) to determine the degree of site compaction relative to laboratory maximum dry density and optimum moisture content.

The laboratory test is charged separately.

Pavement Related

Test - Insitu CBR

Method - BS1377: Part 9, 1990, 4.3

This method is is used to check the quality of sub grade and to determine the strength of granular sub-base (crusher run) during road construction. The test primarily involves shear deformation of the soil beneath a standard 50mm dia. plunger.

* Testing Rate is not inclusive of reaction load. The cost of providing the reaction load shall be borne by the client. For investigation on existing roads, traffic management cost and stipulated working time may have to be considered. 

Test - Pavement Coring (dia.100 or dia.150) mm

This method is used to check the thickness of pavement and the defined layers such as overlay, wearing course, binder course or even Macadam course (old road).

For investigation on existing roads, traffic management cost and stipulated working time may have to be considered.

Test - Dynamic Cone Penetration (DCP)

Method - Ref: TRRL & TRL Ltd., U.K.

This method is used for rapid measurement of the structural properties of existing road pavements with unbound granular materials. The rate of penetration of the cone, when driven by a standard force is inversely related to the CBR test. Where the pavement and sub-grade layers have different strengths, the boundaries between the layers and the thickness of layers can be estimated.

For investigation on existing roads, traffic management cost and stipulated working time may have to be considered.

Concrete Related

Drilling - Concrete Coring (dia.100 mm up to max. 300mm length)  

This method is carried out when standard cube strengths are low. But first ensure that: 

1. the concrete strengths actually failed to meet the specification provisions,

2. low strengths are verified and compared with rebound hammer tests from areas of both questionable and good cube strength results, and

3.  the specified strength is really needed. In many cases, the concrete can be accepted for the intended use.

Test - Compressive Strength (cylindrical), dia.100mm

Method - BS1881: Part 120, 1983

Equipment - Wykeham Farrance, 2000 kN, S/No.12177-1 with Digicon digital readout unit S/No.95828-0

Available at the Laboratory's permanent facility (as above address). This method is used to determine the strength of concrete cores.

"The results of the test are given as the measured core strength or the in-situ cube strength which are without allowance for the effect of curing history, or age, or degree of compaction. The relationship between core and cube strengths is complex and will vary with particular conditions", (BS1881: Part 120, 1983- Forward)

Test - Compressive Strength (cube)

Method - BS1881: Part 116, 1983

Equipment - Wykeham Farrance, 2000 kN, S/No.12177-1 with Digicon digital readout unit S/No.95828-0

Available at the Laboratory's permanent facility (as above address).

Test specimens to be delivered to the Laboratory- refer to NOTE 4

The readout unit has a built-in autorange system whereby the lower range is displayed in 0.1 kN divisions up to 500 kN and on reaching this figure automatically changes to 1.0 kN divisions up to the maximum capacity.

Test - Schmidt Rebound Hammer, 

Method - BS1881: Part 202 - Concrete Test Hammer guide

Hammer Type - Proceq N-34, Serial No:123883

This method is used for the non-destructive measurement of the concrete/mortar compressive strength and the control of the uniform concrete quality (in-situ concrete and prefabricated structures) as well as for detecting weak spots. The compressive strength (fc) is established by measuring the hardness (rebound value R) of the concrete surface and with the conversion curves.
