Pavement rebound deflection tester/Pavement Benkelman deflection beam

Measuring range:

(1) This method is suitable for measuring the rebound deflection of various roadbeds and pavements to assess their overall bearing capacity and can be used in the design of pavement structures.

(2) The rebound deflection value of the roadbed and flexible pavement measured by this method can be used for the handover and completion acceptance.

(3) The rebound deflection of the pavement measured by this method can provide a basis for the highway maintenance management department to formulate a road maintenance plan.

(4) The deflection of the asphalt pavement is based on the standard temperature of 20℃. When testing at other temperatures (over the range of 20±2℃), the deflection value of the asphalt pavement with a thickness of more than 5cm should be corrected by temperature.
