TRB’s second Strategic Highway Research Program (SHRP 2) Renewal Project R06D has released a prepublication, non-edited draft version of a report titled Nondestructive Testing to Identify Delaminations between HMA Layers that explores the ability of nondestructive testing technologies to detect the extent, depth, and severity of delamination in hot mix asphalt pavements. The report also examines the development of the technologies to operate full-lane width at safe traveling speed.
The results of Renewal Project R06F will be incorporated into an electronic repository for practitioners, known as the NDToolbox, which will provide information regarding recommended technologies for the detection of a particular deterioration. The NDToolbox is in the process of being created by SHRP 2 Renewal Project R06A, which has released a prepublication, non-edited draft version of a report titled Nondestructive Testing to Identify Concrete Bridge Deck Deterioration that identifies nondestructive testing technologies for detecting and characterizing common forms of deterioration in concrete bridge decks.
Renewal Project R06F is one of seven follow-on projects to SHRP Renewal Project R06 that produced SHRP 2 Report S2-R06-RW: A Plan for Developing High-Speed, Nondestructive Testing Procedures for Both Design Evaluation and Construction Inspection, which examines existing and emerging nondestructive evaluation (NDE) technologies and their current state of implementation to satisfy the NDE needs for highway renewal.
