Universities and transit agencies across the United States have been finding innovative new ways of providing and financing mobility services on and around university campuses. Many transit agencies are providing substantially more service and moving substantially more riders than their counterparts...

 

In this study, the researchers evaluated the effectiveness of quality control/quality assurance (QC/QA) specifications in decreasing hot mix asphalt (HMA) variability. A questionnaire was written to gather general information about the QC/QA specification programs that are being used in the United States...

 

A variety of portable safety and security barriers for directing traffic (public events, sports facilities, etc.), and securing private and public locations against access (court houses, schools, etc.) have been developed. Some higher capacity systems have been developed for use on and around high speed...

 

The study examined organizational issues that affected employee motivation and retention. To obtain information about these issues that could be qualitatively analyzed and compared from state to state, face-to-face interviews were conducted with two or three individuals at the Minnesota, Iowa, North...

 

This research investigates moisture susceptibility of asphalt mixes; evaluates the effect of various numbers of freeze-thaw cycles on the mechanical properties of asphalt and determines if the Georgia Loaded Wheel Tester can be used to test for moisture induced damage.

 

State Highway Agencies (SHAs) in the United States use smoothness specifications to insure that they are providing the public with quality roads. Monetary incentives / disincentive policies based on the initial roughness values are used by SHAs to encourage contractors to build smoother roads. To justify...

 
Factors Affecting Rail Car Supply (Mar 2001, MPC-01-121)

Depending on your situation, a combination of different programs may have the best return for each organization. By providing descriptions of programs, decision makers are able to better...

 

The objectives of this research were to determine if fly ash has an effect on the field performance of cement-treated bases, determine if cement-treated bases perform similarly to other base types, and develop pavement performance models for interstate and non-interstate roadways in the state of Wyoming.

 

This project used field and laboratory evaluations to study the possibility of incorporating bottom ash in asphalt mixes. A pavement test section was constructed for the field portion of the project. The laboratory evaluations involved design and accelerated testing of control and bottom ash asphalt...
