Laboratory And Field Investigations To Address Erosion, Volume Change And Desiccation Cracking Of Compost Amended Expansive Subsoils
(Civil & Environmental Engineering, 2007-08-23)Desiccations cracks are formed during drying process of fine grained cohesive soils in summer and these cracks often appear on unpaved subgrades due to direct exposure to sun. These cracks allow surface runoff infiltration ... -
Laboratory tests and numerical model of geothermally heated bridge deck with attached hydronic loop
(2020-12-17)An accumulation of ice and snow on pavement slabs and bridge decks always adversely impacts driving conditions and results in motorist accidents. The use of the more popular deicing methods, including plowing, salting, and ... -
Life Cycle Assessment Of Bio-material Stabilized Expansive Soils
(Civil & Environmental Engineering, 2008-09-17)Pavement cracking is one of the major maintenance works that requires millions of dollars in repair costs annually. Pavement cracks are formed due to moisture and temperature fluctuations in the soil. Stabilization of ... -

(2017-01-18)¶One renewable energy source that has witnessed a significant growth in the recent years is wind energy, with the installation of new wind farms around the globe as well as the innovations in wind power technology, which ... -
Long-term Performance Of GFRP Reinforced Concrete Beams And Bars Subjected To Aggressive Environments
(Civil & Environmental Engineering, 2012-07-25)The use of fiber-reinforced polymer (FRP) bars in reinforced concrete (RC) structures has emerged as an alternative to traditional steel reinforcement environments and other applications where steel has shown greater ... -
LONG-TERM SHEAR INVESTIGATION OF POLYPROPYLENE FIBER-REINFORCED CONCRETE BEAMS
(2017-03-02)This study investigates the long-term influence of polypropylene fibers on the shear strength and failure behavior of longitudinally reinforced concrete beams, with or without stirrups, subjected to accelerated aging ... -
MAKING PUBLIC HEALTH PERFORMANCE MEASURES FOR TRANSPORTATION ACCESSIBLE TO PRACTITIONERS
Pollutants emitted into the atmosphere from static and mobile sources pose a threat to human health. The detrimental impact associated with air pollution varies by the type of pollutant, the magnitude, frequency and duration ... -
Managed Lanes Weaving And Access Guideliness
(Civil & Environmental Engineering, 2010-03-03)To maximize the potential for successful managed lanes (MLs) operations, there are critical design issues that require special attention. Adequate ML access spacing and length of the ML access opening are required for the ... -
MECHANICAL RESPONSE OF CHEMICALLY TREATED SULFATE-RICH CLAY UNDER MULTIPLE TRIAXIAL STRESS PATH
(2021-07-21)Expansive clayey soils, which are abundant in arid and semi-arid areas, including the state of Texas, can lead to excessive distress in pavements, foundations, embankments, earth retaining systems and other civil infrastructure ... -
METHANE OXIDATION POTENTIAL OF UNCOMPOSTED YARD WASTE AS A LANDFILL BIOCOVER
(2018-12-18)Biocovers are widely used in landfills to oxidize emissions of the greenhouse gas methane. Biocovers used till date are fully or partially made of composts. Compost takes time and effort to create, and costs about $10 per ... -
MICROPLASTIC RISK CHARACTERIZATION OF PLASTIC ROAD
(2022-12)In recent past, the act of waste recycling has been diversified in manifolds across the world leading to evolution of newer recycling technique and fresh recycled product. Albeit plastic is one of those waste materials ... -
Mode Choice Models For Long Distance Travel In USA
(Civil & Environmental Engineering, 2007-08-23)The influences of technology and economic development on human activity are increasingly taking place on larger spatial scales. As a consequence, complementary interactions between urban regions are getting stronger, which ... -
Model Development for User Behavior While Adopting Autonomous Vehicles as Their On-Demand Transportation Mode
(2022-08-15)Shared autonomous vehicles (SAVs) are a new technology that allows passengers to skip hailing a cab using a smartphone app to summon an autonomous shuttle that does not require a human operator. SAVs are anticipated to ... -
