| 摘 要： | 落锤式弯沉仪(FWD)在道路检测领域得到了广泛的应用,但相应的弯沉温度修正关系尚未建立.为此在某试验路段进行周期1 a的路面弯沉盆数据采集及相应沥青结构层温度监测,建立了基于FWD的沥青路面弯沉温度修正关系,并利用等效层理论及Bossinesq弯沉方程将其扩展到任意沥青厚度下的温度修正公式.通过与美国及我国依据梁式弯沉仪建立的温度修正公式比较发现,3种修正关系存在一定的差异.

| Abstract: | Falling weight deflectometer(FWD) has been widely used in the field of road testing,but the corresponding deflection temperature correction relationship has not yet been established.Aiming at the above condition,one year cycle test of the road surface deflection is taken and the corresponding structural layer temperature of asphalt pavement is monitored on the experiment section,then the relevant temperature correction relation between deflection and pavement temperature are developed.According as the above... |
