    [Industry news] The functions of road surface profiler

    The result of road surface profiler is almost continuous data. The road surface profiler generates far more data than the normal rut bar with 3, 5, or even 10 sensors. The road surface profiler can generate indicator statistics for an operator defined interval. The economic practicability of this technology is more reflected in the data obtained can be used to calculate Ride comfort indicators.

    [Industry news] The functions of an asphalt binder tester

    Chocolate pudding, synthetic rubber, toothpaste and asphalt… At first glance, these items seem to be randomly selected. Although it may not be obvious, these products have a common, basic characteristic-their rheology, or flow and deformation, can be measured with one instrument.

    [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] Should you buy a retroreflectometer?

    Many people know that retroreflectors can make a great contribution to ensuring road safety, but because retro reflector s are not really cheap, many people will hesitate: Should I invest in retroreflectors? Is this a cost-effective business?
