测定沥青路面面层的弯沉值,是目前非破坏性评路面结构强度最常用的一种方法。但由于沥青层的劲度受温度变化的影响,所以用弯沉评价原有路面时,选择一个基准温度和标准荷载作为弯沉测定条件是必要的。但由于现场控制这些条件(基准温度和标准 Determination of the deflection of asphalt pavement surface is the most commonly used method of nondestructive evaluation of pavement structure strength. However, as the stiffness of asphalt layer is affected by temperature changes, it is necessary to select a reference temperature and standard load as the condition of deflection measurement when evaluating the original road surface with deflection. However, due to on-site control of these conditions (reference temperature and standard
