弯沉是鉴定旧路强度和补强设计的一项重要指标,但单纯用一个弯沉指标还难以全面地反映路面的工作状态。在同样弯沉时弯沉盆小的,路面弯曲程度就剧烈,路面损坏就要快些。不少实测资料表明在弯沉值虽低于设计要求而曲率半径过小处,路面均已损坏。 Deflection is to identify the strength of the old road and reinforcement design an important indicator, but simply using a deflection indicator is also difficult to fully reflect the working condition of the road. In the same deflection when sinking basin is small, the degree of bending of the road is intense, the road damage should be faster. Many measured data show that although the deflection value is lower than the design requirements and the radius of curvature is too small, the road has been damaged.
