Asphalt pavement structure layer modulus inversion method fusing multi-source information
The invention discloses an asphalt pavement structure layer modulus inversion method fused with multi-source information, which comprises the following steps of: obtaining pavement deflection and load center structure layer strain information within a certain range of a load center under the action of a load through a drop weight deflectometer test; a pavement structure layer modulus initial value is stipulated and substituted into a forward modeling algorithm, and pavement deflection and structure layer stress of the asphalt pavement structure under the load action of the drop weight deflectometer are calculated; comparing the difference value with a specified threshold value according to the measured value and the calculated value; when the difference value is larger than a specified threshold value, the pavement structure layer modulus parameter continues to be optimized until the difference value between the calculated value and the measured value of the optimized structure layer modulus is smaller than an allowable threshold value, and the structure layer modulus at the moment is the actual pavement structure layer modulus. According to the method, the problem of lack of multi-source information fusion in an existing asphalt pavement structural layer modulus inversion method is solved, and the structural layer modulus inversion calculation precision is improved.
本发明公开了一种融合多源信息的沥青路面结构层模量反演方法，通过落锤式弯沉仪试验，获取荷载作用下，在荷载中心一定范围内的路面弯沉和荷载中心结构层应变信息；规定路面结构层模量初始值，并代入正演算法，计算沥青路面结构在落锤式弯沉仪荷载作用下的路面弯沉和结构层应；根据实测值与计算值，将差值与规定阈值进行对比；当差值大于规定阈值时，继续对路面结构层模量参数进行优化，直至优化后的结构层模量的计算值与实测值的差值小于允许阈值，此时的结构层模量即实际的路面结构层模量。本发明解决了现有的沥青路面结构层模量反演方法中缺少对多源信息融合的问题，提高对结构层模量反演计算精度。
