Electrically-heated pavements have attracted attention as alternatives to the traditional ice/snow removal practices. Electrically conductive polymer-carbon composite coatings provide promising properties for this application. Based on the concept of joule heating, the conductive composite can be utilized as a resistor that generates heat by electric current and increases the surface temperature to melt the ice and snow on the pavement surface. This research investigates the feasibility of applying an electrically conductive composite coating made with a Polyurethane (PU) binder and micrometer-scale carbon fiber (CMF) filler as the electrical heating materials on the surface of Portland cement concrete (PCC) pavements. PU-CMF …

Daily work report (DWR) is a very important data recorded by the inspectors during the construction projects. Although, a lot of time and effort is invested to collect this big amount of DWR data, its use has been limited mostly to the contractor payment and dispute resolution. This study presents the methodological details about utilizing the historical DWR data to automatically generate the schedule for future projects based on the bid data. As a proof of concept of concept, as-built schedules has been developed from the DWR data. The as-built schedule generated can be used as a tool for more …
