Developing Performance-Based Specifications to Improve the Fatigue Life of Asphalt Pavements in Oregon

Creator:: Sreedhar, Shashwath
Abstract:: Asphalt concrete fatigue cracking is recognized as a major distress mode in the U.S. The widespread nature of this distress and the data from agency Pavement Management Systems (PMS) suggest that it is an issue with asphalt mixture design and production processes and is not a problem specific to certain...

Moving towards sustainability and increasing user safety by improving performance of RAP mixtures and developing a network-level decision-making tool for pavement maintenance

Creator:: Haddadi, Sogol Sadat
Abstract:: Due to a general reduction in pavement program funding levels over the past decade, the current budget is not sufficient to maintain roadways at a high level of service with acceptable roughness levels. Rough roadways with poor ride quality increase drivers’ vehicle operating costs (fuel consumption, vehicle maintenance, and tire-wear)...

Consideration of Driver Behavior in the Design of Red Light Extension Systems

Creator:: McCrea, Sarah Anne
Abstract:: Red Light Running (RLR) is a safety hazard at signalized intersections in Oregon and throughout the United States. Various methods of mitigating factors contributing to RLR have been implemented but few protect against a conflict when a vehicles runs a red light. Additionally, current prediction algorithms are complicated; there is...

Consistency and effectiveness of advisory speeds: an evaluation of current posting techniques

Creator:: Rohani, Joshan W.
Abstract:: Crash rates are said to be nearly three times higher on curved sections than those on straight sections of rural roadways. As a result, advisory curve/speed signs are standard practice to mitigate these risks on sharp horizontal curves. The industry standard for determining appropriate and uniform speeds for such signs...

Determination of structural layer properties of aggregate and asphalt surfaced roads

Creator:: Rwebangira, T.
Abstract:: This study involved the determination of the structural layer properties of aggregate and asphalt surfaced pavements for use in the evaluation of pavement load carrying capacity and the seasonal effects of moisture. This was achieved by the use of Nondestructive Testing Methods (NDT) and backcalculation techniques. Pavement surface deflection measurements...

Development of a test procedure for water sensitivity of asphalt concrete mixtures

Creator:: Al-Swailmi, Saleh H.
Abstract:: Environmental factors such as temperature, air, and water can have a profound effect on the durability of asphalt concrete mixtures. In mild climates where good quality aggregates and asphalt cement are available, the major contribution to deterioration may be due to traffic loading and the resultant distress is manifested in...

Evaluation of Oregon Tack Coat Performance to Reduce Tracking and Increase Interlayer Shear Strength of Asphalt Pavements

Creator:: Covey, David J.
Abstract:: CSS-1H is the most commonly used slow-setting emulsion grade in Oregon. “New” engineered emulsions were recently developed in Oregon to reduce tracking, the pick-up of tack coats by construction vehicle tires during construction activities, and increase interlayer shear strength (ISS), the amount of adhesive bond present between layers of asphalt...

Finite element modeling of gusset plate failure using OpenSees

Creator:: Walker, Andrew J.
Abstract:: The collapse of the I-35W Bridge in Minneapolis, MN in 2007 prompted an investigation into the design and inspection of the steel truss bridges. Further investigation into the collapse revealed that a gusset plate experienced sway buckling, causing the bridge failure. This bridge failure motivated research into the analysis and...

Driving simulation : a mechanism for understanding driver response to mobile barriers in work zones

Creator:: Swake, Joshua
Abstract:: Highway construction projects require temporary changes in roadway characteristics, such as the number of operational lanes, lane path, lane width, shoulder width, and posted speed limit. These modifications which are often temporary in nature have the potential to impact driving performance. Many research efforts have focused on developing standards to...

Field and Numerical Investigation of Pavement Vehicle Interaction Related Excess Fuel Consumption and Delamination

Creator:: Estaji, Mostafa
Abstract:: With ever-increasing number of vehicles actively using the state and national roadway network, transportation-related fuel consumption and consequent pavement structural damage rises. In this dissertation, the impact of material-induced dissipated energy mechanisms in asphalt and concrete pavements were analyzed using field measurements in California and finite element modeling of pavement...
