Evaluation of Epoxy Compounds as a Material for Patching and Protecting Concrete


Book Description

The final report summarizes the results of a study of the use of epoxy compounds in the shallow surface repair and sealing of concrete bridge decks. The research effort concentrated on the use of epoxy resin systems as bonded overlays and included evaluations of test strips of seven materials on two structures in Northern Virginia, supplemented by observations of approximately fifty full-scale applications. The wearing of a thin bonded epoxy overlay exposed to traffic, as manifested in the loss of both skid resistance and protection afforded the underlying concrete, is the definitive factor in the service life of the application. The resistance to wearing of the exposed overlays observed in this study was generally disappointing and the use of an asphaltic wearing course to protect the epoxy seal coat was considered essential.

Evaluating Applications of Field Spectroscopy Devices to Fingerprint Commonly Used Construction Materials


Book Description

"TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R06B-RW-1: Evaluating Applications of Field Spectroscopy Devices to Fingerprint Commonly Used Construction Materials documents evaluation results of practical, portable spectroscopic equipment for in-situ analysis of a wide range of commonly used construction materials. The report also includes proposed American Association of State Highway and Transportation Officials (AASHTO) standards of practice for the analysis of titanium content in traffic paints by X-ray fluorescence and identification of chemical admixtures by attenuated total reflectance. The results of Renewal Project R06B, which produced SHRP 2 Report S2-R06B-RW-1, 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 SHRP 2 Report S2-R06A-RR-1: 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 R06B 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"--TRB Website.
