This document is a technical summary of the Federal Highway Administration (FHWA) report, Pavement Structural Evaluation at the Network Level (FHWA-HRT-15-074). It addresses the use of traffic speed deflection devices for the structural evaluation of pavements at the network level. Highlights from three major efforts—gathering information to identify...

Mobility is central to living an independent life, to participating in society, and to maintaining well-being in later life. The point of departure in this thesis is that retirement implies changes in time-space use and interruption in routines, which influence demands and preconditions for mobility in different ways.  The aim of this thesis is to explore...

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...

The National Academy of Engineering has released a report that presents 25 activities and programs that are considered exemplary in their approach to infusing ethics into the development of engineering students. It is intended to serve as a resource for institutions of higher education seeking to enhance their efforts in this area. Ethical practice in...

Seal coats are one of many techniques commonly used for asphalt pavement preservation and chip seals are the most commonly used in Minnesota. In some applications, chip seals are not the best surface treatment alternative, such as in areas with frequent or high stress turning movements like cul-de-sacs or intersections, and can suffer chip loss and/or bleeding...

Intersection conflict warning systems (ICWS) are intended to reduce the frequency of crashes by alerting drivers of conflicting vehicles on adjacent approaches at unsignalized intersections, particularly those with one-way or two-way stop control. Few studies have explored the safety effectiveness of ICWS; the effectiveness has not been shown for four-legged...

Engineered fills, including compacted granular fill and reinforced soil, are a cost-effective alternative to conventional bridge foundation systems; however, limited guidance exists on estimating the settlement and lateral deformation of these features under service conditions. Additionally, the stress distribution within these features is not well understood,...

To improve the safety at school bus stops, the Ohio Department of Transportation (ODOT) conducted a study to identify available technologies or methods that could actively warn motorists of the presence of a school bus at an upcoming school bus stop. A scan of the current practice found that all States use static School Bus Stop Ahead signs similar to Ohio...

This guide provides information and resources to help transportation management, operations, and maintenance staff incorporate climate change into their planning and ongoing activities. It is intended for practitioners involved in the day-to-day management, operations, and maintenance of surface transportation systems at State and local agencies. The guide...

Accurate traffic counts are important for budgeting, traffic planning, and roadway design. With thousands of centerline miles of roadways, it is not possible to install continuous counters at all locations of interest (e.g., intersections). Therefore, at the vast majority of locations, MnDOT samples axle counts for short durations, called portable traffic...
