Deflections measured with a Benkelman Beam for D6.4-Nantes full-scale testing report

Deflections were measured with a Benkelman Beam, the principle of which is similar to the FWD. A load of 65 kN is used to reproduce the passage of a rolling load but a low speed close to 3 km/h (at a frequency close to 1 Hz). During each series of measurements, 4 measurements were made on each pavement section. Benkelman beam measurements were performed at 0, 50 000, 100 000, 200 000, 500 000, 750 000, 1 000 000 and 1 050 000 loads. It is related with deliverable 6.4: Nantes full-scale testing report (https://cordis.europa.eu/project/id/860441/results): figures 36 and 55

本数据集采用贝克曼梁（Benkelman Beam）开展弯沉测量，其工作原理与落锤式弯沉仪（Falling Weight Deflectometer，FWD）相似。试验采用65 kN荷载模拟滚动荷载的作用过程，加载速度接近3 km/h（对应荷载频率约1 Hz）。每一组测量流程中，每个路面测试断面均完成4次测量。贝克曼梁测量分别在0、50000、100000、200000、500000、750000、1000000及1050000次荷载作用后开展。本数据集与交付成果6.4：《南特全尺寸试验报告》（https://cordis.europa.eu/project/id/860441/results）中的图36和图55相关联。
