Benkleman Beam Price in Nigeria

The Benkleman Beam Price in Nigeria is an important consideration for road construction companies, highway agencies, civil engineering consultants, asphalt contractors and materials-testing laboratories. A Benkelman Beam, also commonly spelled Benkelman beam, is a pavement testing instrument used to measure the rebound deflection of flexible road pavements under a specified wheel load. The test helps engineers assess pavement strength, structural condition and maintenance requirements. In Nigeria, the price depends on the beam design, dimensions, dial gauge, accessories, manufacturing quality and whether the equipment is supplied as a complete testing set.

Features & Specifications of Benkelman Beam

A Benkelman Beam is a portable, lever-arm pavement testing instrument. It measures the vertical rebound deflection of a flexible pavement when a loaded test vehicle moves away from a measurement point. Engineers use the readings to evaluate pavement response and support road maintenance, rehabilitation and structural assessment.

Main features

* Pavement deflection measurement: Measures the rebound movement of flexible road pavement under a specified wheel load.
* Lever-arm mechanism: Uses a pivoted probe beam to magnify the pavement movement at the dial indicator.
* Dial gauge or digital indicator: Provides a measurable reading of vertical movement. Some models require the gauge to be purchased separately.
* Lightweight construction: Many models use aluminium components to make transportation easier.
* Adjustable support feet: Help position and level the reference frame on the road surface.
* Portable or dismantlable design: Some models separate into sections for easier storage and transportation.
* Vibrator system: Selected models include a battery-operated vibrator to help ensure free movement of the beam components.
* Field application: Designed for use with a loaded test vehicle during pavement deflection surveys.

How to Install Benkelman Beam

The Benkelman Beam is generally assembled at the test location. Follow the manufacturer’s instructions for the exact model.

* Unpack the equipment: Remove the beam sections, support frame, dial gauge, feet and accessories from the carrying case.
* Inspect all components: Check the probe, reference beam, pivot, joints, gauge bracket and support feet for damage.
* Assemble the beam: Connect the dismantled sections using the manufacturer’s supplied fittings and tools.
* Position the support frame: Place the reference frame on a firm, stable road surface near the test point.
* Fit the probe beam: Insert and secure the probe in its correct position through the pivot arrangement.
* Install the dial gauge: Mount the dial indicator on its bracket and ensure that its measuring contact is correctly positioned.
* Level the instrument: Adjust the support feet and use the supplied spirit level, where fitted, to establish the correct position.
* Set the gauge to zero: Follow the manufacturer’s procedure for setting the initial dial reading.
* Check the beam movement: Move or test the mechanism according to the manual to ensure that the probe and pivot move freely.
* Verify calibration: Use the manufacturer’s calibration procedure or an approved calibration device before field measurements.

Important field-testing precaution: A Benkelman Beam test requires a suitably loaded test vehicle, correct axle load and tyre pressure, safe traffic control and trained operators. Do not use an assumed vehicle load or tyre pressure; follow the applicable test procedure and project specification. Benkelman Beam Survey Manual Edit.doc +2

16 Frequently Asked Questions About Benkelman Beam

These are common search-intent questions written in a Google People Also Ask style. They are not claimed to be a verbatim capture of Google’s live Nigeria results.

1. What is a Benkelman Beam?

A Benkelman Beam is a pavement testing instrument used to measure the rebound deflection of flexible road surfaces under a specified wheel load.

2. What is a Benkelman Beam used for?

It is used for pavement deflection surveys, road condition assessment, pavement evaluation, maintenance planning and highway rehabilitation investigations.

3. How much is a Benkelman Beam in Nigeria?

Available Nigerian listings indicate approximately ₦450,000–₦1,500,000, with one advertised apparatus listing at ₦1,200,000. The final price depends on the model and accessories.

4. What is the principle of a Benkelman Beam?

It works on the lever-arm principle. The probe rests on the pavement, and pavement movement is transmitted through the beam mechanism to a dial gauge or digital indicator.

5. What is the standard for Benkelman Beam testing?

Commonly referenced standards include AASHTO T 256 and ASTM D4695. The correct procedure should be confirmed against the applicable project specification.

6. What is the lever ratio of a Benkelman Beam?

Many standard models have a 2:1 lever ratio. This means the dial indicator movement is twice the pavement movement, so the reading must be interpreted according to the instrument design and test procedure.

7. What is the length of a Benkelman Beam?

The dimensions vary by model. A common design has a 2.44 m probe section and a 1.22 m rear extension, with an operating length of approximately 3.7 m.

8. How does a Benkelman Beam test work?

The probe is positioned between the dual tyres of a loaded test vehicle. The dial reading is observed as the vehicle moves forward and the pavement rebounds.

9. What load is used for a Benkelman Beam test?

A commonly referenced test arrangement uses an approximately 80 kN (18,000 lb) single axle load. The exact axle load and tyre pressure must follow the specified test method.

10. What is the difference between a Benkelman Beam and a Falling Weight Deflectometer?

A Benkelman Beam measures pavement rebound under a slowly moving or static wheel-load test arrangement. A Falling Weight Deflectometer applies an impulse load and uses sensors to measure pavement response, often at multiple offsets.

11. What type of dial gauge is used with a Benkelman Beam?

Depending on the model, a mechanical or digital displacement indicator can be used. Common examples include 25 mm travel gauges with graduations or resolutions specified by the manufacturer.

12. Is a Benkelman Beam used for flexible pavement?

Yes. Its main application is measuring the deflection response of flexible pavements under wheel loading.

13. Can a Benkelman Beam measure rigid pavement deflection?

It is primarily designed for flexible pavement deflection testing. Other instruments and test methods may be more suitable for particular rigid pavement investigations.

14. How do you calibrate a Benkelman Beam?

Calibration should follow the manufacturer’s procedure, using an appropriate calibration device or reference arrangement to verify the gauge and lever mechanism. Keep calibration records for quality assurance.

15. Where can I buy a Benkelman Beam in Nigeria?

You can contact laboratory and civil engineering equipment suppliers, including IFYTEX INDUSTRIAL EQUIPMENT at F96Up, Alaba International Market, Lagos, for availability and quotations.

16. Where can I download a Benkelman Beam manual PDF?

You can consult the manufacturer’s operating instructions, the Bangladesh Roads and Highways Department Benkelman Beam survey manual and the NZ Transport Agency test procedure. Ensure the document matches your equipment and required testing method.
