Pavement deflection instrument

Test methods

Suitable for determining the elastic deflection value of pavement when loading pure soil or loading at very slow speed.

,

Can reflect the overall strength of the road well.

A. Connect the instrument levers back and forth in one piece and check them as required.

B. One truck, the single axle of the rear axle shall be calibrated according to the regulations, used for road loading, and the pneumatic tire pressure is also adjusted according to the regulations.

C, thermal resistance test a ~ accuracy ° C, used to determine the road surface temperature (due to the deflection value with temperature).

D. Three sides of the red flag for traffic control, three small iron bars 700~300mm, diameter 20

It is made by the principle of leverage and is used to measure the deflection of the road between the two wheels of the rear axle of the car. The instrument has the characteristics of simple structure, convenient use, high sensitivity, and light and fast structure. It is not affected by objective conditions such as weather, wind, and sunshine.

Can reflect the overall strength of the road well.

The pavement deflection instrument is an essential tool for assessing the structural integrity of roads. It helps engineers and technicians evaluate how much the road surface deforms under load, which directly relates to its long-term durability and safety. This device is particularly useful in areas where heavy vehicles are common, as it ensures that the road can withstand continuous stress without significant damage.

Its design allows for easy handling and accurate readings, making it ideal for field applications. The calibration process ensures reliable results, and the ability to adjust for environmental factors like temperature increases the precision of measurements. Whether conducting routine maintenance or preparing for new construction projects, this instrument provides valuable insights into the condition of the pavement.

With its robust build and user-friendly interface, the pavement deflection instrument is a must-have for any transportation or civil engineering team looking to maintain high standards of road quality and safety.
