Description

Technical Field

[0002] Pavement flatness refers to the deviation of the longitudinal concavity and convexity of the road surface. Pavement flatness is an important indicator in pavement evaluation and pavement construction acceptance, and mainly reflects the flatness of the pavement longitudinal section profile curve. When the pavement longitudinal section profile curve is relatively smooth, it means that the pavement is relatively flat, or the flatness is relatively good, otherwise it means that the flatness is relatively poor. A good pavement requires good pavement flatness as well. After the construction of a highway is completed, the pavement flatness needs to be tested, and pavement flatness testing equipment is needed.
