Life Cycle Cost Analysis Rehabilitation Costs
The purpose of this study is to evaluate the cost of rehabilitation techniques used on interstates, state highways, and principal arterials dating back to 2009 for use in LCCAs. The rehabilitation techniques used in this study include cold in-place recycling, hot in-place recycling, full-depth reclamation, hot-mix asphalt overlays, hot-mix asphalt mill-and-fill, and portland cement concrete pavement. Hot in-place recycling was further broken into three categories; heater remixing, heater repaving, and heater scarifying.This study evaluates data from CDOT’s Cost Data books and Pavement Management Program. Cost indices were used to normalize project data to year 2014. Data analyzed in the study was obtained from the CDOT’s Cost Data books and the Pavement Management Program. Cost indices were used to nominalize project data to year 2014. The results were obtained for heater remixing (process mat, rejuvenating agent, and furnish hot-mix asphalt), heater scarifying and its rejuvenating agent, cold in-place recycling process (rejuvenating agent and hydrated lime), and full-depth reclamation. Concrete, hot-mix asphalt overlays and hot-mix asphalt mill-and-fill projects were categorized by quantities less than or greater than 10,000 square yards or tons. Subcategories of thickness were made for concrete and product type for asphalt.
