Augmenting the Applicability and Efficiency of Ecological Engineering Solutions for Water Quality Improvement
(2010)
The design options available to the ecological engineer were expanded by exploring new sustainable water quality improvement techniques, specifically the applicability of passive treatment of acid mine drainage (AMD) in ...
EVALUATION OF RHEOLOGICAL PROPERTIES OF ASPHALT BINDERS FOR PAVEMENT DESIGN APPLICATIONS
(2011)
More that 90% of the total paved roadways in the U.S. are asphalt concrete (AC) pavements. The annual expenditures for construction and maintenance of these pavements exceed $10 billion. To reduce these maintenance costs, ...
Exploring the Relationship Between Grain Configuration and the Movement Of Capillary-Held Water in Unsaturated Porous Media
(2019)
The air-water interface in porous media has been studied for decades, and is important for understanding the distribution and movement of water, solutes and suspended colloids and nanoparticles in the unsaturated zone. The ...
A STUDY ON THE INFLUENCE OF SELECTED GEOGRID INDEX PROPERTIES ON THEIR IN-AGGREGATE PERFORMANCE
(2013)
Geogrids are polymer-based products which are commonly used to reinforce soil walls, steep slopes and roadway bases. Inclusion of geogrids as aggregate base reinforcement, with proper installation, has been shown to result ...
A LABORATORY INVESTIGATION AND MODELING OF DYNAMIC MODULUS OF ASPHALT MIXES FOR PAVEMENT APPLICATIONS
(2011)
Traditionally, stiffness of hot mix asphalt (HMA) has been used as a measure of the pavement's ability to carry vehicular traffic loads without undergoing excessive deformation. Early deterioration of pavements due to ...
Characterization of Rutting in Asphalt Pavements using Laboratory Testing
(2019)
In asphalt pavements, rutting is one of the main concerns at high in-service temperature, which can occur either through plastic flow or shear in structural layers. Rutting depends on several factors, such as asphalt binder ...
SEISMIC AND QUASI-STATIC LATERAL LOAD BEHAVIOR OF PILE GROUPS IN IMPROVED SOFT CLAY: CENTRIFUGE AND NUMERICAL MODELING
(2015-12-18)
In the design of pile foundations subjected to lateral loading, one of the objectives is to restrict the lateral displacements. Improving the soil surrounding the pile foundation is an innovative and cost-efficient solution ...
DEVELOPMENT OF A PROTOTYPE IN-SITU FATIGUE SENSOR FOR STRUCTURAL HEALTH MONITORING OF HIGHWAY BRIDGES
(2010)
Fatigue damage to bridges has been identified as a threat to bridge safety. Fatigue cracks usually occur at stresses lower than the anticipated design stress levels. Unlike yielding or corrosion, fatigue cracks are seldom ...
Soil-Structure Interaction Studies for Understanding the Behavior of Integral Abutment Bridges
(2013)
Integral Abutment Bridges (IABs) are increasingly being used to eliminate undesirable effects of bridge joints on the long-term performance of bridges. Behavior of abutments in IABs is, however, poorly understood. ...
