TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-R06D-RW-2: Nondestructive Testing to Identify Delaminations Between HMA Layers, Volume 2 describes the theoretical models used in the development of nondestructive testing (NDT) techniques capable of detecting and quantifying delaminations in HMA pavements. SHRP 2 Report S2-R06D-RW-2 was developed as part of SHRP 2 Renewal Project R06D that generated a sizable amount of documentation regarding the findings of evaluations and equipment development. The report for SHRP 2 Renewal Project R06D is therefore divided into five volumes. Volume 1 is a comprehensive summary of the study. Volumes 2 through 5 provide more detailed technical information and are web-only. The topics covered in other volumes are: Volume 3: Controlled Evaluation Reports (http://www.trb.org/Main/Blurbs/168812.aspx), Volume 4: Uncontrolled Evaluation Reports (http://www.trb.org/Main/Blurbs/168813.aspx), and Volume 5: Field Core Verification (http://www.trb.org/Main/Blurbs/168814.aspx) (Author/publisher)
