Description

Technical Field

[0002] Deflection refers to the deformation of the roadbed and pavement before and after the load acts on the roadbed / pavement, and is calculated in 1 / 100 mm. Before a highway is renovated, deflection measurements need to be carried out on the original highway to understand the road conditions of the original highway and serve as a guide for design. During or after highway construction, deflection measurements can be used to verify whether the construction of the roadbed / pavement meets the design strength requirements.
