EVALUATING APPLICATIONS OF FIELD SPECTROSCOPY DEVICES TO FINGERPRINT COMMONLY USED CONSTRUCTION MATERIALS(R06B)
Products from this research inlude:
1) Proposed American Association of State Highway and Transportation Officials (AASHTO) standards of practice for the analysis of titanium content in traffic paint by X-ray fluorescence (XRF) and identification of cement admixtures and RAP-modified asphalt by attenuated total reflectance (ATR),
2) A spectra database for the tested materials aField operation manuals for ATR and CRF instruments,
3) A Final report, and
4) A Pilot report.
|
The library of spectra for the tested materials can be used to identify these materials in the field.
The proposed AASHTO standards will be useful to quality assurance and quality control personnel and research and material divisions in transportation agencies.
The field operation manuals were developed for ATR and XRF instruments to supplement the standards. These manuals will be useful to field personnel who will conduct spectroscopic testing; however, the variability in the available instruments requires that the specific technical manual for each instrument should also be consulted.

This project is now complete. The report and associated materials are all available here.
