This article outlines the ultrasound data employed to calibrate in the laboratory an analytical model that permits the calculation of the depth of partial-depth surface-initiated cracks on bituminous pavements using this non-destructive technique. This initial calibration is required so that the model provides sufficient precision during practical application. The ultrasonic pulse transit times were measured on beam samples of different asphalt mixtures (semi-dense asphalt concrete AC-S; asphalt concrete for very thin layers BBTM; and porous asphalt PA). The cracks on the laboratory samples were simulated by means of notches of variable depths. With the data of ultrasound transmission time ratios, curve-fittings were carried out on the analytical model, thus determining the regression parameters and their statistical dispersion. The calibrated models obtained from laboratory datasets were subsequently applied to auscultate the evolution of the crack depth after microwaves exposure in the research article entitled "Top-down cracking self-healing of asphalt pavements with steel filler from industrial waste applying microwaves" (Franesqui et al., 2017) [1].
本文概述了在实验室中用于校准一个分析模型的超声数据，该模型允许使用这种无损技术计算沥青路面部分深度表面引发裂缝的深度。需要进行这种初始校准，以便该模型在实际应用中提供足够的精度。在不同沥青混合料（半密集沥青混凝土AC-S；超薄层沥青混凝土BBTM；以及多孔沥青PA）的梁式样本上测量了超声脉冲传播时间。通过不同深度的切口模拟实验室样本上的裂缝。利用超声传播时间比的数据，对分析模型进行曲线拟合，从而确定回归参数及其统计离散度。从实验室数据集获得的校准模型随后被应用于听诊在题为《利用工业废料中的钢填料通过微波实现沥青路面自上而下裂缝的自愈》（弗拉内斯基等人，2017年）[1]的研究文章中微波暴露后裂缝深度的演变情况。
