Falling Weight Deflectometer (FWD) di Jakarta

The Falling Weight Deflectometer (FWD) is a trailer-mounted, non-destructive, high-precision, testing system used to evaluate pavement conditions and physical properties. It simulates the load when a car passes over the pavement to measure its vertical deflection response to that load. It is convenient, fast, safe and labor-saving, and is suitable for long-distance and continuous measurement.

FWD is mainly composed of the main frame, operating mechanism, falling weight assembly, hydraulic system, sensor system, electrical system, monitoring and safety guidance system, etc. Equipped with data acquisition and processing software, which can record the original data of deflection, load, temperature and relevant pavement information such as pile number, realize data normalization processing, various error calculations, etc., and analyze the data and make them into charts and reports. It can accurately assess the structural condition of highways, local roads, parking lots and airport runways, and can also be applied to roadbeds and subbases during construction. It is widely used in road research, design, reconstruction and pavement management.

STANDARD : ASTM D4694-96

FEATURES:

• Fully automatic "one-touch" operation. A "one-touch" button is installed in the cab. After reaching the test position, the user only needs to press the button and the equipment will automatically run. After the test is completed, the equipment will automatically be locked for transportation.
• The single-point detection and collection time is within 20 seconds (three times of lifting and dropping the hammer and collecting data are completed in accordance with the specifications).
• High measurement accuracy. The FWD system is scientifically designed. High-performance sensors, high-precision and high-speed data acquisition system, and customized digital signal processing algorithms ensure the accuracy and reliability of deflection data.
• Safety interlock protection device. An interlocking joint is installed between the deflectometer and the test vehicle. During the movement of the test vehicle, the equipment is in a protected state and operation is not allowed, which effectively protects the safety of the equipment and the test vehicle.
• It has dual synchronous lifting platforms, which makes data collection more stable and improves data accuracy.
• Each main function has an alternative second solution (or function) to improve the reliability of the whole equipment.

Falling Weight Deflectometer (FWD) di Jakarta

Simulated Load: The FWD is typically a trailer-mounted system towed by a vehicle. It operates by dropping a known weight from a specific height onto a circular load plate placed on the pavement surface. This creates a short-duration load pulse (typically 30-60 milliseconds) that closely mimics the impact of a moving heavy vehicle wheel.

Deflection Measurement: As the pavement deforms under the load, a series of deflection sensors (typically geophones) arranged radially from the center of the load plate measure the vertical deflection at various distances. These measurements create a "deflection basin" profile, which is a curve representing the deformation of the pavement layers.

Data Analysis: The collected data—the magnitude of the applied load and the measured deflections—are then used in a process called backcalculation. This is a complex, iterative computer-based analysis that uses the deflection basin data and known pavement layer thicknesses to calculate the elastic modulus (stiffness) of each individual pavement layer, including the asphalt, base, and subgrade.

Reporting: The output of the FWD test is a comprehensive report on the structural health of the pavement, which helps engineers identify weak layers, detect voids beneath concrete slabs, assess load transfer efficiency at joints, and make informed decisions on maintenance and rehabilitation.

Applications

The FWD is an indispensable tool in pavement engineering and management systems. Its key applications include :

Pavement Condition Assessment : It provides a rapid and accurate way to evaluate the structural integrity and uniformity of existing pavements.

Overlay Design : The FWD data is used to determine the required thickness of a new asphalt overlay to extend the life of a road.

Quality Control : It's used on new construction projects to verify that the compacted layers meet design specifications.

Forensic Studies : The FWD helps in investigating the causes of pavement distress and failure.

Load Rating : It can be used to assess the capacity of pavements to handle super-heavy loads.
