Pavement Deflection Tester 5.4m Beckman Beam Pavement Deflection Tester Rebound Deflection Tester 3.6 7.2m

Pavement resilient modulus testing equipment(Benkelman Beam)

The Beckman beam method is a method suitable for measuring the elastic deflection value of the road surface under static loading or very slow speed loading, and it can well reflect the overall strength of the road surface.

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.
