Product Name: Pavement Deflection Instrument 1. Overview of the Pavement Deflection Instrument The pavement deflection instrument is a specialized tool used to measure the elastic deflection of road surfaces under static or slow-moving loads. It is particularly effective when testing pure soil or applying very low-speed loading conditions. This device provides a reliable assessment of the overall structural strength of the road, helping engineers and technicians make informed decisions about maintenance and construction. 2. Testing Methods A. Connect the instrument's levers as a single unit and perform checks according to the required specifications. B. Calibrate the rear axle of a single truck according to regulations for road testing. Adjust the pneumatic tire pressure as specified during the process. C. Use a thermal resistance meter with precision of ±0.5°C to measure the surface temperature of the road. Temperature plays a crucial role in determining deflection values, as the deformation of the pavement can vary with environmental conditions. D. Set up three red flags for traffic control and use three small iron bars measuring 700–300 mm in length, with a diameter of 20 mm.
