Abstract: The plastic sheeting approach for negative skin friction reduction in end-bent piles behind proprietary mechanically stabilized earth walls was investigated along with the conventional bitumen coating method. A number of ...

Abstract: An analysis, supported by experiment, is presented of the performance of a typical critical flow meter having a restriction in the form of another nozzle or orifice downstream of its discharge. ...

Abstract: This study was concerned with vibrations induced during drilled shaft construction on green concrete in adjacent drilled shafts. To characterize the types of vibrations, a full-scale field test was conducted using a 0.9-m ...

Abstract: There is risk involved in any construction project. A contractor's quality assurance system is essential in preventing problems and the reoccurrence of problems. This system ensures consistent quality for the contractor's ...

Abstract: Alternative earthen final covers are being considered throughout North America as cost-effective alternatives to prescriptive covers. Regulatory agencies typically require field testing to demonstrate the equivalency of ...

Abstract: Out-of-plane stresses due to the wedging effect of the strands caused high stress concentration at the end of the transition zone of Florida bulbtee girders. Adding the hydrostatic stresses due to grout pressure in the ...

Abstract: The precision of pavement moduli values is affected by the selection process of the signals from the seismic pavement analyzer (SPA). If improper signals were selected, moduli values from the SPA were lower than those ...

Abstract: The secondary spiral and skin reinforcement in the anchorage zone of prestressed posttensioned girders causes congestion and poses difficulty in the placement of concrete. It is also labor intensive to produce and place ...

Abstract: A gaseous flow is employed as heat transfer fluid (HTF) in a parabolic trough solar collector (PTSC) for simultaneous production of cooling at three different levels of temperature to meet the demands of air conditioning, ...

Abstract: Thermal energy storage (TES) plays a pivotal role in a wide array of energy systems, offering a highly effective means to harness renewable energy sources, trim energy consumption and costs, reduce environmental impact, ...
