Pavement deflection instrument

product manual

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.

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. Not affected by weather, wind, sunshine and other objective conditions
