摘　　要：以京港澳高速公路沥青路面为研究对象,采用落锤式弯沉仪(FWD)对不同试验路段路面的弯沉进行检测并分析弯沉盆参数(Deflcetion Basin Parameters,DBP),同时用反算软件SIDMOD、BISAR软件分别进行弯沉盆模量反演、结构受力理论分析,得出典型病害与模量对应关系。Taking the asphalt pavement of the Beijing-Hong Kong-Macao Expressway as the research object,the deflection of different test sections was detected by the falling weight deflection meter(FWD),and the time of the deflection basin parameter(DBP)was analyzed.The software SIDMOD and BISAR respectively carried out the inversion of the deflection basin modulus and the theoretical analysis of the structural force.

关 键 词：沥青路面 落锤式弯沉仪(FWD) 弯沉盆参数(DBP) 斜率 模量反算 模量衰减
