Performance of Cement Treated Recycled Aggregates under Wetting-Drying Cycles in Pavement Base
(2017-06-08)Resilient Modulus (MR) is one of the most important stiffness parameter to determine the thickness of a pavement layer (AASHTO 2003 pavement design guideline). Recent studies conducted by researchers on the variability of ... -
PERFORMANCE OF CONCRETE SLABS WITH EMBEDDED HYDRONIC LOOPS FOR GEOTHERMALLY BASED BRIDGE DE-ICING APPLICATIONS
(2019-05-14)Geothermal energy has always been available as a renewable thermal reserve, however, only recently has it been unlocked as a potential source of energy to de-ice bridges and roadways. The ability to efficiently extract the ... -
Performance Of Full-scale Ultra-high Performance Fiber-reinforced Concrete Column Subjected To Extreme Earthquake-type Loading And Effect Of Surface Preparation On The Cohesion And Friction Factors Of The AASHTO Interface Shear Equation
Buildings in areas of high seismicity may be subjected to large axial stresses as well as severe earthquake loading. In order to protect the integrity of these buildings, concrete columns must possess high compressive ... -
Performance Of Large Diameter Polyvinyl Chloride (PVC) Pipes In Water Applications
(Civil & Environmental Engineering, 2014-03-10)Polyvinyl chloride (PVC) pipes with diameters greater than 24" make up a small fraction of water utilities. Most of the research done on PVC pipes in water utilities focuses on diameters less than 24". Therefore, this ... -
