TRB’s second Strategic Highway Research Program (SHRP 2) Renewal Project R06C has released a prepublication, non-edited draft version of a report titled Using Both Infrared and High-Speed Ground Penetrating Radar for Uniformity Measurements on New HMA Layers that explores infrared imaging and ground penetrating radar technologies as non-destructive techniques to assess hot-mix asphalt (HMA) density and degree of segregation. The report also includes suggestions for how these technologies can be incorporated into existing department of transportation specifications for verifying HMA construction quality.
The results of Renewal Project R06C 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 R06C 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.
