【摘要】 本文以5条试验路的实测数据为基础,对落锤式弯沉仪（FWD）和贝克曼梁式弯沉仪（BB）两种不同性质荷载作用下的路表实测弯沉、弯沉盆进行了较系统的对比分析。结论认为,实测弯沉δ_FWD与δ_BB有一定的差异,但两者存在良好的相关关系。更多还原

【Abstract】 The falling Weight Deflectometer (FWD) and Benkelman beam (BB) were compared side-by-side on five experimental pavements, including four asphalt conerete pavenments and one crushed rock pavement, comparisons of the deflection basins and the deflection variations within pavement test sections were made, Equations correlating FWD deflections with BB measurements were derived.更多还原
