• 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.

• 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.

• 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.

• How does an falling weight deflectometer work

  Pavement structure and Bridges, DAMS and other civil structures are different. Its service life is relatively short. After a period of time, the road will be damaged, resulting in a decline in pavement performance. It affects the driving safety and comfort. It will also affect residents along the way. Therefore we must take appropriate repair method to restore the use of the pavement quality. The choice of suitable repair method depends on the accurate evaluation of pavement condition, among which the evaluation of pavement structure's bearing capacity is an important part of pavement condition evaluation.
