Wind energy must be commercially competitive to be economically sustainable. Existing wind farms in Ireland must be more efficient to meet the 2009 EU Renewable Energy Directive target of 7% of total energy demand from onshore wind energy farms, which is 45% of the total national renewable energy target of 16%. WindPearl - a Sustainable EnergyAuthority of Ireland (SEAI) funded project is currently looking into improvin operations & maintenance (O&M) of onshore wind turbine farms in Ireland.

Civil Engineering Research in Ireland 2020
Bitumen emulsions are used for a range of road maintenance applications, including surface dressing, gravel seals, slurry seals, tack coating, cold-mix asphalt and in situ pavement recycling. The emulsions used can be classified as being either cationic (i.e. possessing a positive electrostatic surface charge) or anionic (i.e. carrying a negative electrostatic surface charge). The vast majority of emulsions used for such applications in Europe are cationic, while anionic bitumen emulsions are used widely throughout North America and Africa. The aims of the experimental study described in this paper were (a) to investigate why one or the other emulsion type is …

A Review Of Vision Based Methods For Pothole Detection And Road Profile Analysis, Darragh Lydon, Su Taylor, Myra Lydon, Julia Early
Civil Engineering Research in Ireland 2020
This paper is an overview of the development and application of Computer Vision for the detection of pothole, pavement distress and road profile analysis and categorisation. A brief explanation of the traditional methods for determining these factors is given, followed by a chronological description of the evolution and the challenges of using Computer Vision (CV) approaches to determine these conditions. The paper is separated into sections aligned to image capture and analysis methodologies. Qualitative evaluations and comparison of these methods have been provided along with the proposal of guidelines for new computer vision-based road analysis systems.

Analysis And Optimisation Of Tii’S Pams Reset Values And Deterioration Models For Irish Pavement Conditions, James Quinn, Raymond Mcgowan, Tomas O'Flaherty
Civil Engineering Research in Ireland 2020
Ireland has a national road network of approximately 5300km that is managed by Transport Infrastructure Ireland (TII). TII create yearly pavement maintenance and renewal programs from the operation of a Pavement Asset Management System (PAMS). Accurate pavement deterioration models and reset values are an essential part of PAMS and are required for life cycle cost analysis (LCCA). Pavement maintenance and renewal schemes are prioritised based on the LCCA's largest benefit to cost ratio, and therefore optimise the annual pavement maintenance and renewal budget. Currently, TII implement pavement deterioration models and reset values from Austria's and Belgium's PAMS, and are not …

An Analysis Of The Effectiveness Of Bitumen Additives On The Performance Of Pavement Surface Dressings, Alan Anderson, John Casserly, Alan Kavanagh, Jim Campbell
Civil Engineering Research in Ireland 2020
Surface dressing is a maintenance technique that uses thin layers of bitumen emulsion and single sized aggregates. The surface dressing process seals and binds the surface of a road to protect its substructure from water ingress. It also provides increased skid resistance, which improves safety for road users. Early life chip-loss can occur if there is an insufficient degree of adhesion between the emulsion and aggregate used. The range of additives used in bitumen can have an effect on their adhesion properties. The focus of this research project was to investigate if the use of these additives in surface dressing …

The article compares the results of laboratory tests of dispersed soils to determine their strength characteristics. For this purpose, soils were tested on devices with three-axis compression and single-plane cut. In calculations for clay and sandy soils, indicators of their strength properties are used, which include such characteristics as the angle of internal friction φ and specific adhesion c. Based on the results of this work, recommendations on the practical application of the obtained soil characteristics for the geo-information geotechnical database of Astana were compiled.

In the article, based on the basic law of point dynamics with non-ideal connection of theoretical mechanics, the speed of the car movement on each section of the descending part of the marshalling hump. A generalized model of the speed of the car at the calculated point of the marshalling hump is obtained. This model made it possible to calculate the instantaneous values of the speed of the car from the top of the hill to the calculated point in a continuous mode. This made it possible to speed up the process of plotting changes in accelerations, speeds, and time …
