    在加速加载试验过程中,采用落锤式弯沉仪测量不同轴载作用次数下路面弯沉,反算沥青层模量,得到路面整个寿命周期的沥青层模量衰减模型.结果表明,累积疲劳损伤下,沥青层模量与加载作用在半对数坐标成线性相关.

    Falling weight deflectometer Was used tomeasure the deflection of surface pavement under different ALF axle loading in accelerated loading test.Back-calculated the modulus of asphalt layer.determined the reduetion in modulus of the asphalt layer during the whole life of pavement are presented.The result shows a linear relationship between asphalt layer modulus and cumulative fatigue damage plated on semilog scales.
