最初的分组讨论确定了与使用现有无损检测(NDT)数据和反计算(BC)程序相关的更常见的问题和限制。这些问题包括(1)如何适应刚性层效果的深度，(2)需要适应材料的非线性行为，(3)无法检测“薄层”的贡献，以及(4)BC模数是反映和包括路面系统影响的“有效”模数的事实，而不是唯一的材料/土壤属性。关于分组讨论中涉及的具体问题的更多细节将予以介绍。
Initial breakout group discussions identified the more frequently encountered problems and limitations associated with the use of existing nondestructive testing (NDT) data and backcalculation (BC) procedures. They include (1) how to accommodate depth to stiff layer effects, (2) the need to accommodate nonlinear material behavior, (3) the inability to detect the contribution of "thin layers", and (4) the fact that BC moduli are "effective" moduli that reflect and include the impact of the pavement system, and are not unique material/soil properties. More details concerning specific issues covered in the breakout group deliberations are presented.
