    A falling weight deflectometer is a testing device used to measure the physical properties of pavement. Other testing types are destructive; therefore, they have been used widely to assess pavement properties. The information gathered using the device can be used to determine the capacity of the pavement structure.

     

    Falling weight deflectometer testing!

    Structural evaluation is a study of pavement that enables road owners to develop accurate or realistic programs, allowing for better budgetary requirements to be met. By applying a specific load, we can assess the remaining life of the pavement by evaluating its structural integrity. This helps you determine what traffic patterns require changes or rehabilitation.  

     

    Testing of pavement strength

    Pavement structural integrity can be estimated with testing. A heavy vehicle can pose stress to the pavement structure, which can result in an deformed road structure.

    Key benefits:

    • Automated and rapid structural payment testing is applied to all the pavements according to the requirements.
    • The device not only produces fast readings but also provides accurate readings up to 60 test points.
    • The device easily determines the failure layer.
    • The compact design of the device makes it easy to transport.
    • The device provides immediate deflection data, enabling engineers to assess requirements during any construction surveying or maintenance project easily.
    • The device can be repeated multiple times without changing the measurement answers, making it also a cost-effective cost-effective process to determine structural integrity.
    • A range of options is compared, including plane off and recycling, as well as overlays.
    • Better and more accurate structural data can be collected to improve the accuracy and structure.
    • The device's precision makes it reliable for evaluating road or pavement conditions.
    • The device can be used in extreme temperatures, from the hottest and driest desserts to the humid areas. The device works great, except in extreme temperature conditions or other adverse weather conditions.
    • One of the most significant advantages of the device is that it is a non-destructive test drive that can be efficiently operated by a single person.
    • It can be used in new construction, road maintenance, pavement rehabilitation, and airport pavements.

     

    What is the use of falling weight testing?

    Data collected by the device can be used to check the structural integrity of the pavement or road. It helps in easily understanding the underground conditions. One can obtain accurate information regarding road strength, including layer types, surface layers, subgrade layers, and so on. This information can be used to check the overlay requirements, which helps determine the remaining life of the pavement or if the pavement‘s structure is damaged and is unable to bear more weight from vehicles. The device helps save a significant amount of money, as only the damaged section of the road can be renewed rather than replacing the entire road. Overlay requirements can easily be identified using the tool. During construction surveillance, a pavement engineer could not deny the critical role of the device, as it helps in determining the structural strength without causing any destruction.
