| 摘 要： | 通过落锤式弯沉仪检测并计算出路面各层的动态模量,可得到路面各结构层的承载力状况,从而评价路面各层的强度。现场检测实例表明：FWD检测能较为准确和快速地判断出在道路交叉口这个特殊受力路段中车辙发生的原因与位置,这将避免后期维修处治的盲目性,提高维修处治的效率和效果。

| Abstract: | Falling Weight Deflectometer(FWD)is used to detect and calculate the dynamic module of each layer of pavement,deducing the bearing status of each structure layer of pavement to evaluate the strength of each layer of pavement.Field detection shows that FWD can identify the rut's cause and position correctly and quickly at the intersection which is a special bearing section.It can avoid the blindness of later maintenance and treatment and improve the efficiency and effect of maintenance and treatment. |
