Recommendation of RILEM TC237-SIB on cohesion test of recycled asphalt
2018
This recommendation describes how to evaluate the presence of potentially active bitumen in recycled asphalt (RA) materials through the cohesion test. The experimental protocol is designed according to the research performed by the RILEM Technical Committee 237-SIB ‘‘Testing and characterization of sustainable innovative bituminous materials and systems’’ with the purpose, to develop a new, simple and fast method for the characterization of RA while limiting the need for conventional rheological tests. The guidelines in this recommendation focus on the testing procedure including specimen preparation, data analysis and provide information on the preparation of a tests report.
Constructive Variants for Personalised Formwork
2018
Abstract The aim of this paper is to explore the possibility of working with a personalized reusable composite formwork in order to obtain architectural shapes for roof and wall elements without material loss. Starting with the analysis of the market needs, the definition of the functions and continuing with the conceptual and technical solution proposals, we created a formwork variant that can be reused for different complex shapes. The researches set on sight different variations of the material used, their thickness and the contact surface given by the support elements.
Compression Garments in Sport
2019
Abstract In this chapter we summarize the main scientific information regarding the applications of compression garments in sports. This chapter covers the discussion from the clinical compression’s application in patients to how its use has been extended to sport. In addition, the composition and different kinds of textiles are considered regarding the level of compression and methodologies/standards for its classification. The chapter is organized in sections considering the effects of compression garments on physiological, psychological, strength, power, endurance, and muscle activation parameters, and ends with indications of future research directions and methodological aspects regardi…
A HOLISTIC MULTI-METHODOLOGY FOR SUSTAINABLE RENOVATION
2019
A review of the barriers for building renovation has revealed a lack of methodologies, which can promote sustainability objectives and assist various stakeholders during the design stage of building renovation/retrofitting projects. The purpose of this paper is to develop a Holistic Multi-methodology for Sustainable Renovation, which aims to deal with complexity of renovation projects. It provides a framework through which to involve the different stakeholders in the design process to improve group learning and group decision-making, and hence make the building renovation design process more robust and efficient. Therefore, the paper discusses the essence of multifaceted barriers in buildin…
Improving data quality in construction engineering projects : an action design research approach
2014
Aurthor's version of an article in the journal: Journal of Management in Engineering. Also available from the publisher at: http://dx.doi.org/10.1061/(ASCE)ME.1943-5479.0000202 The topic of data and information quality (DQ/IQ) is a longstanding issue of interest in both academia and practice in the construction engineering field. Poor DQ/IQ has led to poor engineering drawings that, in turn, have led to delays and, eventually, cost overruns. In this paper, a study is reported that took an action design research (ADR) approach to develop and evaluate a DQ/IQ assessment tool, which is called the information quality system (IQS), in a large global engineering and construction company. The eval…
Action Research as a Proactive Research Method for Construction Engineering and Management
2010
Academic research in applied disciplines such as construction engineering and management (CEM) has the dual mission of simultaneously contributing to the solution of practical problems and creating theoretical and conceptual knowledge. To do so, appropriate research approaches are needed. However, extant literature in the field has paid little attention to this issue and research methods used have been almost entirely either quantitative surveys or case studies. In this paper, action research (AR) is proposed as an answer to this knowledge gap. AR aims at building and testing theory within the context of solving an immediate practical problem in a real setting. The paper describes the under…
Investigation of Wood Materials by Combined Application of X-ray and Neutron Imaging Techniques*
2014
Abstract Conservation of cultural heritage is extremely important not only from a cultural point of view, but also from a practical one. It is our duty to pass on to future generations the cultural heritage left to us by our ancestors. Wood is one of the most common materials used to generate works of art which are in a state of constant change and/or deterioration. In order to optimize the knowledge of artworks together with their conservation, it is necessary to use the most advanced scientific and technological tools. In the following paper, we will show the tomographic results which can be achieved by application of complementary techniques based on the combined use of X-ray and neutron…
Implementing climate impacts in road infrastructure in the design phase by combining BIM with LCA
2019
Abstract Building information modelling (BIM) software is increasingly being used in as a visual road design tool and offers real-time information on material demands as designs change. Life cycle assessment (LCA) is a tool that is used to measure the lifetime environmental impacts of systems, materials and processes. LCA data sets are organized according to process or product, which is ideal for implementation as a parameter in BIM. This paper seeks to explore how BIM and LCA can be used together in road design by analysing existing literature, creating a Norwegian test case on a road designed in a BIM model and adding LCA data to the model before comparing to a standard LCA study of the s…
Sustainability for 3DP Operations
2020
Sustainability is an essential consideration in manufacturing, and within this chapter a detailed appraisal is given to sustainability for 3D printing. An in-depth review of existing research is provided, and a cradle-to-grave assessment technique is shown to assess the environmental impact of 3D printed part.
