• Abstract:
  Rubberized Asphalt Chip Seal (RACS) has been used for several decades to protect the bridges in South Dakota. RACS, among other things, prevents South Dakota Department of Transportation from evaluating the integrity of the bridge decks in an efficient and accurate manner. This study investigated methods to remove the RACS layer from the bridges in South Dakota. The procedure followed during the investigation was to first examine numerous options available for RACS removal. These were organized into a "decision matrix" and a formal procedure was followed to extract the most likely candidate methods for further investigation, namely, scraping, high pressure washing, and melting. Scraping with heating was deemed to be the method with the most potential for success, and a full-scale field test was conducted on an I-90 bridge deck. The report concludes with a recommended implementation procedure.
