A periodic monitoring of the pavement condition facilitates a cost-effective distribution of the
resources available for maintenance of the road infrastructure network. The task can be
accurately carried out using ...
Phosphorus (P) in agricultural runoff is a major pollutant in many of Ireland's surface waters. Identification of areas that are at a high risk for P loss to surface waters is a critical component of river basin management. ...
There are numerous studies on the dynamic amplification factors caused by traffic
flow on a bridge. For short- and medium-span bridges, the road profile appears as a
dominant parameter on the bridge dynamic response. In ...
Upland headwater streams are dynamic systems, responding rapidly to changes in climatic conditions. This study examined the effects of a catastrophic rainfall event, that occured on 24 October 2011 on the east coast of ...
Jet grouting is a ground improvement technique that has become widely adopted over the past three decades, yet relatively little data has been published about performance characteristics of mixes under adverse conditions, ...
To predict characteristic extreme traffic load effects, simulations are sometimes performed of bridge loading events. To generalize the truck weight data, statistical distributions are fitted to histograms of weight ...
In line with the increasing studies on the beneficial reuse of alum sludge from a “waste” into useful raw material, this paper reports an in-depth investigation of the effects of ageing time on the structure and the phosphate ...
Accurate traffic loading models based on measured data are essential for the accurate assessment
of existing bridges. There are well-established methods for the Monte Carlo simulation of single lanes
of traffic, and this ...
Critical static bridge loading scenarios are often expressed in terms of the number of vehicles that are present on the bridge at the time of occurrence of maximum lifetime load effect. For example, 1-truck, 2-truck, 3-truck ...
This paper presents the results of ongoing research on the mechanical performance of a 20mm binder course asphalt pavement mix incorporating recycled asphalt pavement (RAP). A series of binder course mixes were designed ...
This paper presents the physical properties of Recycled Asphalt Pavement (RAP) and its influence on the mechanical performance of a binder course asphalt pavement mix. A series of binder course mixes were designed containing ...
A road develops permanent deformation and fatigue damage because of the strains induced in its
structure by surface loading and environmental change. A mechanistic-empirical approach is
implemented here to simulate the ...
This paper reports results from a numerical model to calculate subgrade settlement
in railway tracks due to repeated dynamic loading. The trains are modelled as rigid
body 2-axle carriages on two layers of springs. The ...
This study explores influences on flood frequency distributions in Irish rivers. Generalised Extreme Value (GEV) type I distributions are recommended in Ireland for estimating flood quantiles. This paper presents the ...
A three-tiered, enterprise, GIS architecture offers a robust, efficient, and secure platform to potentially revolutionize disaster management by enabling support of all of the phases of governmental activity that must occur ...
Waterworks sludge continues to be an inescapable by-product of the potable water treatment process. Accordingly, final disposal of the sludge remains one of the most significant pressing problems for the potable water ...
The Multichannel Analysis of Surface Waves (MASW) technique, used
to determine shear wave velocity (Vs) and hence small strain stiffness (Gmax), has
recently generated considerable interest in the geophysics community. ...
Full-flow penetrometers have been shown to overcome problems experienced with the cone penetrometer when measuring resistance in very soft peat and organic soil, and give a much more uniform measure of resistance than the ...
Sustainability in the construction industry can only be achieved through a radical rethinking of building construction and reuse. This paper outlines the problems and offers innovative solutions that embrace technological ...
Third level educators are increasingly being called on to clarify the nature of the education they provide and the contribution of their graduates to society. There is therefore considerable interest in the generic attributes ...
