The objective of this research was to assess the efficacy of various waterproofing sealers applied to pavement joints with respect to limiting water ingress. The measure of water ingress was the chloride concentration profile as measured by scanning electron microscopy and energy dispersive spectroscopy. The fieldwork was conducted at the MnROAD facility....

Part-time shoulder use is the conversion of shoulders to travel lanes during some hours of day as a congestion relief strategy. This strategy is also known as temporary shoulder use or hard shoulder running, and is typically implemented on freeways. Part-time shoulder use is a transportation system management and operations (TSM&O) strategy that uses...

During the last ten years, dry road marking retro reflectivity has been measured by the use of mobile equipment. However, due to a growing interest in the performance of wet road markings, the use of road markings with a profiled surface is common in many European countries today. When measuring this type of marking with the use of mobile equipment in wet...
