Comparative Damage Of Different Truck Configurations On Jointed Plain Concrete Pavement
(Civil & Environmental Engineering, 2009-09-16)
This study estimated the damage done by trucks with 35 different configurations on a typical structure of a Jointed Plain Concrete Pavement. The configurations were proposed by New York Department of Transportation, the ...
Studies On Field Stabilization Methods To Prevent Surficial Slope Failures Of Earth Fill Dams
(Civil & Environmental Engineering, 2009-09-16)
Surficial failures are occurring frequently on the slopes of earthfill dams which are predominantly rainfall induced. Desiccation cracks form on the slope surface during dry environment which accelerates infiltration during ...
Clay Mineralogy Effects On Long-term Performance Of Chemically Treated Expansive Clays
(Civil & Environmental Engineering, 2009-09-16)
Stabilization of expansive soils using chemical additives such as cement and lime had been in use for several decades and these treatments provide riding comforts to travelers. However, many state Departments of Transportation ...
Performance Of Large Scale Steel Fiber Reinforced Concrete Deep Beam With Single Opening Under Monotonic Loading
(Civil & Environmental Engineering, 2009-09-16)
The design of complex, discontinuous stress trajectory regions (D-regions) is complex in natureand cumbersome to design. The performance of a large scale steel fiber reinforced concrete (SFRC)deep beam with single opening ...
Multi-criteria Assessment For Supporting Freeway Operations And Management Systems
(Civil & Environmental Engineering, 2009-09-16)
Freeway traffic congestion represents an increasing concern for urban areas throughout the United States. In addition, faced with limited roadway expansion alternatives, transportation agencies are considering investment ...
Statistical Approach To The Development Of A Microscale Model For Estimating Exhaust Emissions Of Light Duty Gasoline Vehicles
(Civil & Environmental Engineering, 2009-09-16)
Today, air pollution is taking a growing toll on human health, the environment and the economy, despite decades of efforts to combat it. Although it was once a primary urban phenomenon in industrialized countries, today ...
Assessing Control Strategies For Ground Level Ozone
(Civil & Environmental Engineering, 2009-09-16)
Developing cost effective control strategies for ozone has been a challenge to air quality modelers. Conventionally, the control strategies are applied across-the board to the region. The main aim of this research was to ...
Capacity Of Two-sided Type C On Freeway With Four Lanes
(Civil & Environmental Engineering, 2009-09-16)
Weaving segments are categorized based on weaving length, configuration, number of lanes, free flow speed and weaving ratio. All these parameters affect weaving capacity. One of the objectives of this research was to extend ...
Adsorption Curve Fits For Landfill VOCs On Bituminous Coal Based And Coconut Shell Based Activated Carbon
(Civil & Environmental Engineering, 2009-09-16)
This study explores adsorption as a method of controlling hazardous gas emissions from Municipal Solid Waste Landfills (MSWL). In particular, the hazardous air pollutants (HAPs) para, meta, and ortho-xylene, ethylbenzene ...
