The Pavement Preservation Research Roadmap, originally developed between 2006 and 2008 as the Transportation System Preservation (TSP) Research, Development, and Implementation Roadmap and including both pavements and bridges, was updated under a contract with the Federal Highway Administration (FHWA). The Roadmap is intended for use by State, loca

HFST is a pavement surface treatment consisting of a polymer resin binder used to bond a 1‒3 mm nominal-size polish- and abrasion-resistant aggregate to the pavement surface. HFST is a safety treatment used specifically to restore or enhance the friction of virtually any pavement surface in order to reduce roadway departure crashes. HFST provides a

There is a lot of global experience with fixed fire fighting systems in road tunnels, particularly in Australia and Japan, but also in several recently constructed tunnels in the United States and Europe. The U.S. first implemented FFFS in their tunnels in the 1950s, however, this approach did not become routine, partly due to unsuccessful tests of

According to the 2017 National Household Travel Survey (NHTS), Americans ages 5+ reported more than 42.5 billion trips by walking or biking. These trips averaged 1 mile in length and 16 minutes in duration and comprised almost 12% of all trips annually (across all modes and purposes). Definitionally, non-motorized trips (i.e., walking and biking) i

Work zones are a necessary part of the life cycle of our streets, roads, and highways. They provide a safe area for workers and a safe route for road users around needed road work activity (construction, maintenance, utility). Although work zones play a critical role, they can also be a major cause of congestion and delay. Every spring, the Federal

Inertial profilers can produce valid measurements of longitudinal road profile when they are operated under favorable conditions. However, their performance deteriorates when the host vehicle travels at low speed, decelerates, or comes to a stop. These limitations have hindered the application of inertial profilers for measurement of roughness on l

Nondestructive deflection testing has played an important role in pavement evaluation, design, and management for several decades. During this period, the tool of choice for structural evaluation has been the falling weight deflectometer (FWD), due to its ability to accurately measure very small pavement deflections by means of a nondestructive loa
