(ASCE, 2009-02)It is well accepted that the quality of soft clay samples obtained using standard fixed piston samplers can be relatively poor and that block samples are necessary to yield very high quality samples. However for many ...
-
(ASCE, 2011)This paper provides a quantification of the inputs for an existing qualitative foundation project planning model, namely ARUP’s Sustainable Project Appraisal Routine (SPeAR) diagram. The goal is to provide an improved ...
-
(Elsevier, 2007-01)This research develops a weighted integer goal-programming model for prioritising railway projects for investment. The goal of the model is to prioritise the identified projects for investment while maximising the objectives ...
-
(2005-05)A systematic assessment scheme for determining the alkali reactivity of aggregates has been developed for international use. Expansion tests were conducted on Irish aggregates. Aggregates were subjected to a sequence of ...
-
(ENEA, 2010)The assessment of site-specific bridge traffic loading using WIM data is a critical feature of minimizing the cost of rehabilitation and replacement for bridge stock. For short- to medium-span bridges, it is often assumed ...
-
(CRC Press, 2012-07-08)This paper summarises the developments in the dynamic response of bridges to traffic loading based on a large amount of simulations and field tests carried out within the 6th EU framework ARCHES (2006-2009). When assessing ...
-
(Elsevier Science, 1996)This paper highlights areas of inaccuracy in current modelling techniques for bridge decks with wide cantilevers. A 3-D grilllage model known as the upstand grillage is assessed by comparing its behaviour with that of a ...
-
(Elsevier, 2007-05)This paper presents a novel approach to the reduction of short-span bridge dynamic responses to heavy vehicle crossing events. The reductions are achieved through adjustment of the vehicle suspension damping coefficient ...
-
(Elsevier, 2011-10)This paper examines whether regional characteristics can have a significant impact on the engine sizes of the car fleet in Ireland. Disposable income is found to be the dominant factor in determining the purchase ...
-
(American Society of Civil Engineering (ASCE), 2010-06)Despite billions of dollars of annual exposure from claims and litigation related to construction-induced damage, there are no quantitatively based, agreed upon standards or procedures as to what constitutes due diligence ...
-
(Elsevier, 2004-10-29)The fate of ammoniacal-nitrogen (NH4-N) was studied in a lab-scale downflow reed bed system treating an artificial landfill leachate. Individual reed beds were submerged by the leachate, then drained and rinsed by tap ...
-
(Elsevier, 2011-04)This study investigated the glyphosate adsorption by water treatment residual (termed as alum sludge) in dewatered form (DAS) and liquid form (LAS). Batch adsorption tests were carried out with DAS at different pH, particle ...
-
(Taylor & Francis, 2001-10-05)This report gives results of some new studies performed to validate the European road traffic load model proposed by the Eurocode EC1. Weight in motion has developed greatly in the last ten years and confidence in the ...
-
(Taylor & Francis, 2008-06)The purpose of this study is to optimize adsorption conditions of powdered alum sludge (PAS) as low-cost adsorbent for the removal of three P-species (ortho-P, poly-P and organic-P) from wastewater using the response surface ...
-
(Institution of Civil Engineers, 2012-01)Practising engineers in the Dublin, Ireland, area have much experience in dealing with the boulder clay which underlies much of the city. However, significant deposits of estuarine soils, some of them soft, exist along the ...
-
(Institution of Civil Engineers, 2012-01)A good number of deep excavations have been recently completed in Dublin Boulder Clay, Ireland. These have included propped walls up to 25 m deep and permanent cantilevers 7.5 m high. Experience elsewhere in the world was ...
-
(Taylor & Francis, 2007-10)The adsorption equilibrium of a wide range of phosphorus species by an aluminium-based water treatment sludge (Al-WTS) was examined in this study. Four kinds of adsorption-isotherm models, namely Langmuir, Freundlich, ...
-
(Elsevier, 2008-03-01)The aluminium content in dewatered aluminium-coagulated water treatment residual (DAC-WTR) can lead to a high phosphorus (P) removal capacity. Therefore, DAC-WTR has been used as adsorbent/soil amendment to remove P in ...
-
(Elsevier, 2006-02)A cost efficient way of investigating shallow sediments and for collecting soils data for many offshore geotechnical problems, e.g. anchoring of floating structures with suction piles or evaluation of submarine slope ...
-
A review on numerous modeling approaches for effective, economical and ecological treatment wetlands (Elsevier, 2011-03)Constructed wetlands (CWs) for wastewater treatment have evolved substantially over the last decades and have been recognized as an effective means of “green technology” for wastewater treatment. This paper reviews the ...
