Reclaimed asphalt pavement (RAP) is already being recycled as a construction and building material. One of the commonly considered applications is to create an unbound aggregate from this material. However, since the particles of RAP have binder coatings, traditional quality control procedures applied during construction such as use of a nuclear density gauge does not provide accurate results. Therefore there is a need to find another method that can be applied during construction to confirm that the placement in the field meets the design criteria. For this reason, in this study, the suitability of using light weight deflectometer (LWD) has been investigated. The presented methodology outlines how to implement the use of LWD to create a target modulus in the laboratory as part of design criteria and compare with the field measurements. In the field, depending on the thickness of the constructed aggregate layer, the LWD measurements may be influenced by more than just the layer of interest. The presented methodology also provides a solution for such multilayer conditions. Although the study primarily focuses on using RAP as the investigated material, the methodology developed in this study can be applied to any type of unbound aggregate as demonstrated in this study.

再生的沥青路面（RAP）已作为建筑和建筑材料进行回收。普遍考虑的应用之一是用这种材料创建未绑定的聚合。但是，由于RAP的颗粒具有粘合剂涂层，因此在施工过程中采用的传统质量控制程序（例如使用核密度计）无法提供准确的结果。因此，需要找到另一种可以在施工过程中应用的方法，以确认现场的布置符合设计标准。因此，在本研究中，已经研究了使用轻型偏转计（LWD）的适用性。提出的方法概述了如何将LWD的使用作为设计标准的一部分在实验室中创建目标模量，并与现场测量结果进行比较。在现场，取决于所构造的骨料层的厚度，随钻测井的测量结果可能不仅受感兴趣层的影响。提出的方法还为这种多层条件提供了解决方案。尽管该研究主要集中于使用RAP作为被调查材料，但本研究中开发的方法可以应用于本研究中证明的任何类型的未结合骨料。
