Across the United States, state and local transportation agencies are tasked with collecting transverse profile measurements. Collection of the data is carried out with a variety of systems that operate at the prevailing speed limit. With the wide range ofsystems used to collect data it is critical that transportation agencies know the system used

Stringless paving is the process of constructing a pavement using non-contact, electronic guidance systems to control the paver elevation and steering without the aid of string lines. Contractors across the United States are switching their primary method of paving from string line to stringless control. The differences between the two processes sh

Reusing old concrete pavement as an aggregate source for new pavement construction can lead to significant cost savings, reductions in virgin material usage, and overall sustainability benefits. This was demonstrated on a concrete pavement reconstruction project on I-10, a ten-lane divided interstate located on the west side of Houston, Texas.
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

The Federal Highway Administration (FHWA) with the assistance of the Volpe Center Acoustics Facility conducted a study to quantify the agreement of FHWA’s Traffic Noise Model Version 3.0 (TNM 3.0) with measured highway noise data and with predictions from TNM 2.5. Forthis phase of validation, 281 hours of traffic noise data were collected at 14 hig

Travelers depend on the U.S. transportation system every day to meet commitments for work and friends and family, acquire/deliver goods and services, and respond to emergencies. If the system operates as expected and enables travel within a predictable amount of time, we can rely on it. When it doesn't, we can't. This lack of reliability affects ou
