Effects Of Aggregate Angularity On Mix Design Characteristics And Pavement Performance, Yong-Rak Kim, Leonardo T. Souza

Nebraska Department of Transportation: Research Reports

This research targeted two primary purposes: to estimate current aggregate angularity test methods and to evaluate current aggregate angularity requirements in the Nebraska asphalt mixture/pavement specification. To meet the first research objective, various aggregate angularity tests were estimated with the same sets of aggregates and were compared by investigating their characteristics on testing repeatability, cost, testing time, workability, and sensitivity of test results. For the second objective, the effect of aggregate angularity on mixture performance was investigated by conducting laboratory performance tests (the uniaxial static creep test and the indirect tensile fracture energy test) of five mixes designed with different …

Investigation And Mitigation Of Driver Confusion At Modern Roundabouts, Aemal Khattak, Gregory Mcknight, Karen Schurr, Ram R. Bishu Oct 2009

Investigation And Mitigation Of Driver Confusion At Modern Roundabouts, Aemal Khattak, Gregory Mcknight, Karen Schurr, Ram R. Bishu

Nebraska Department of Transportation: Research Reports

Construction of modern roundabouts in place of traditional four-legged intersections is becoming common in the United States. Roundabout negotiation can be confusing for drivers who are not familiar with their use. This research was carried out to identify roundabout elements that play a role in incorrect roundabout negotiation, ascertain driver characteristics prominent in incorrect roundabout negotiation, assess the relative potential for incorrect negotiation amongst different groups of drivers, and suggest measures for improving drivers’ abilities to negotiate roundabouts. Potential for incorrect roundabout negotiation was measured by asking questions in a survey questionnaire related to rules of roundabout negotiation and the …
