    [Industry news] The application of falling weight deflectometer

    Since the evaluation indicators and standards specified in the current specification are based on the beckman beam test, the data measured by the falling weight deflectometer must be converted into beckman beam data through comparison test before strength evaluation can be carried out. However, the transformation relationship obtained by this simple regression analysis lost a lot of information of the measured data (especially dynamic information), and did not give play to the advantage of the measured sinker data form to evaluate the bearing capacity of the pavement structure.

    [Industry news] The analysis of falling weight deflectormeter

    With the development of road traffic infrastructure construction, more and more attention has been paid to the quality of road construction. Falling Weight Deflectometer has also become an important tool that is increasingly being valued by civil engineers. The falling weight deflectometer is one of the most advanced non-destructive testing equipment for pavement strength in the world. The working principle is as follows: the falling weight deflectometer measures the dynamic deflection of the road surface and inversely calculates the rebound modulus of the road surface. It has become a hot topic in the highway industry around the world.

    [Industry news] How to use an asphalt binder tester?

    Modified asphalt has been an area where the MATC project investigates implementation challenges and shares experiences with the asphalt community. The asphalt binder tester is involved in several field projects evaluating modified asphalt binders and mixtures. The main challenge in describing the properties of modified asphalt binders involves a suitable asphalt binder tester test method. Observations from field studies indicate that the concentric cylindrical geometry provides a promising tool for characterizing the rheological properties of modified asphalt binders.
